Placed jpgs - pdf much bigger then jpgs filesize - why !?

Hi,
i can't understand what exactly indesign doing, hopefully someone got an idea..
thanks in advance..
I placed a few jpgs, which are overall about 1.4 mb. The final Pdf, which only includes these jpgs is much bigger, 3.3 mb. I tried different export settings (best quality, smallest filesize, played with image compression ..) but the pdfs filesize always was between 2.8 (bad quality..) and 3.9.
In another test i printed the jpgs directly in a pdf file with Adobe PDF Printer directly from Windows Photo Viewer. Filesize was a few percent smaller than the original jpgs, Quality was pretty the same.
Finaly i placed these Pdfs in indesign and export the whole document as Pdf -> 2.3 mb
whyy ?!

Exported PDF supports a large number of features not supported in distilled PDF and contains information beyond just the text and images you place on the page, like color management information as one example. Some older versions of ID also tend to export overly large PDF, but that has mostly been corrected in CS5 and later. You can try running the PDF Optimizer in Acrobat Pro to reduce size.

Why is the saved JPG file much bigger than the original JPG file??

I used Image Processor in Bridge CS5 to open a jpeg, apply sharpening action and save as a jpeg. The bit size, color space and pixel dimensions are identical. However, when I save at Quality 12 I get a Jpeg file that is nearly DOUBLE the size of the original jpeg Only if I drop it to Quality 10 do I get a file that approximates, but doesn't equal, the original jpeg.
1) Isn't 12 the same as saying 100% and as such the file size should be the about the same?
2) why would it increase so much? Example about 6 mb to about 12mb???
Does this sound right? I am sure I am doing the steps and setting the parameters correctly. The action simply applies unsharp mask:
I can set the quality to 10 and get an approximate equivalent file size...but I want the higher quality of a 100%/12 setting.
WHAT AM I MISSING???
Thanks - Kevin

WHAT AM I MISSING???
The simple fact that JPEG is always a fully re-compressing format. Your newly created files bear no relationship to the original ones - no binary data structures are retained; the compression algorithm is always applied fresh upon the fully decoded original image and if you use different settings, the result is different. Moreover, since the initial compression artifacts become "valid pixels" once decoded, the successive compression has no way of knowing that they actually are "bad pixels" and those fine disturbances agfain result in different compression patterns. That is, after alll, why consecutive saves to JPEG will always degrade quality even at the best settings...

Database MUCH bigger then original photo's

I'm having problems with the fact that the database is growing too fast. I just started over again after installing version 3. I added photo's with a total size of 7GB. I added geo and face info and after that the database was already 30 GB in size. What am I doing wrong?
Thanks for the help!

The answer is Previews and pre-generated thumbnails, and possibly photos you sent to plug-ins as they are now TIFF files. If you shoot JPEG's and they are you masters Your library is ALWAYS going to be bigger than your original photos by a large extent. If you turn off previews, change the dimensions of your preview settings - or get rid of previews you don't want that helps somewhat but...
Here is the deal if you shoot large res RAW files and take away the size of the actual RAW files your library is usually smaller. If you shoot JPEG's and have previews it will ABSOLUTELY be bigger than your original images even taking into account your original images. Most likely it will even be bigger with thumbnails and overhead that the original files as well.
Check this out to fine tune it a bit.

Ps. if your RAWs are compressed and not high res the library may be bigger to but it sounds like you shoot JPEG if you only have 7Gigs of images - I shoot more than that in a day.

Image covert to PDF then file size become much bigger. [iOS]

When I use picture covert to PDF then converted PDF file size become much bigger. Original picture file size is 2MB but PDF file size become 5.2MB. I'm using iPhone6.
however when I using desktop acrobat to covert the same image then PDF file sizw almost the same as original image file size.

Hi Brian,
I have created a bug report for this issue. We will try to address the issue in a future release of Acrobat DC for iOS.
In the meantime, would you use the web interface to convert your photos to PDFs?
Open Safari on your iPhone.
Go to https://cloud.acrobat.com
Sign in with your Adobe ID.
Select the Create PDF tab.
Tap "Select Files to Convert to PDF".
Tap "Choose Files from My Computer".
Select the photo(s) that you want to covert.
Tap Done.
The converted PDF document(s) will be stored in the Document Cloud.
Please see the following document to switch the file location to Document Cloud in Acrobat DC for iOS.
How to manage files in Acrobat DC for iOS
Sorry for the inconvenience. Hope that the Create PDF option via the web interface is a feasible workaround for you.

Adobe X PDF files converted to jpg, edited and converted back to PDF have ragged, unclear text. I didn't have this problem with Acrobat 9 standard. What is the remedy for this. If this is the best I can expect, I won't be able to use X standard.

I can't imagine any worse workflow than converting to JPEG to edit text, then back to PDF. Text in a PDF is a vector thing, smooth at all resolutions. And JPEG is made for photos. EVERY conversion to JPEG and back loses quality but how much loss there is will vary.
If you must go to an image format, try PNG.

How to make screenshot/jpg/pdf of ENTIRE long Safari window (not just visible part)?

I want to get a "screenshot" (i.e. an image in any format -- PNG, JPG, PDF, whatever) of a looooooooong Safari window diplaying a Web page that entends far below the bottom of the visible screen area and has to be scrolled down to see all of it.
I know about the standard screenshot keyboard tricks in 10.6 -- Command-shift-4, Command-shift-4 then spacebar/click, Command-shift-3, etc. But not any of them allow the user to get a screen shot of the entirety of a long/deep window -- they only capture what is visible on the screen.
Also, another trick people often mention is to "print" (command-P) the Safari page, but instead of sending it to a printer choose "Save as PDF." Brilliant -- except that for some reason I've never been able to "print" a Safari page -- as soon as I hit the command-P keystrokes in Safari, I immediately get a spinning beachball that will only go a way with a force-quit of Safari. This has always been true on this computer (MacBook Pro) -- not sure if it's a common bug or if it's just an eccentricity of my particular machine. Either way, that option is off the table because "printing" is impossible with my Safari.
I also searched around for various third-party freeware applications, and despite a lot of grandiose promises, none of them actually was able to capture an entire window including portions not currently visible on the screen.
I did find a commercial application called SnapWeb that does have the capability to do exactly what I want -- but it doesn't produce usable images in demo mode and requires $$$ to unlock and work properly, something I'm currently unwilling to pay for a simple one-use gimmick that simply must be part of the OS already.
So my question is:
Is there any native way within the 10.6 OS that allows users to capture an entire long Safari window as an image file (not as a Web Archive, but as an image file composed of pixels), which includes the entirety of a Web page no matter how "long" it is, even if it extends far below the visible screen footprint?
And if there is no native way in 10.6, if there a freeware/shareware application/widget/plugin/whatever which does the same thing?
I already know about a commercial software that does it (SnapWeb), so I don't need more recommendations for paid apps. And I know that I can laboriously construct a JPEG by hand with Photoshop by taking a screenshot of the visible window, scrolling down a little, taking another screenshot, etc. etc., and then
"stitching" them together. Yeah, it's possible (and in fact is what I've done in the past), but it's a time-consuming hassle that shouldn't be necessary.
Help! I've wondered about how to do this for years, and have never yet found a satisfactory answer.

Woo-hoo!
After fiddling with Paparazzi! for another 40 minutes, I finally deciphered (through trial-and-error) how to maneuver through its awkward user-interface to an extent that I was finally able to make it "work" -- at least work sufficiently for my purposes. And lo and behold, it does indeed have the capacity to capture a screenshot of an entire long Web page, including the portion not visible on the screen. In fact my first attempt was to experiment with this very page of our thread on Apple "Discussions" about how to solve this problem -- and I got Paparazzi! to save it as a jpeg!! The whole thread, top to bottom, exactly as on the screen, not re-formatted for printing. The final file size was 985 pixels wide by 4,204 pixels long (1.2mb).
I have since experimented with a couple other pages and had success with them as well.
HOWEVER, I can't guarantee that Paparazzi! will work with every page on the Web, because I think one of the problems when I first attempted to use it was that the page I was trying to get a screenshot of contained a lot of Flash elements and other data-heavy widgets, and I think those messed up Paparazzi!'s memory or overwhelmed it or something. But perhaps such huge and problematic pages are rare enough to not be much of an issue using Paparazzi! under normal circumstances.
So, I'll consider this problem "solved," and give user "jsd2" a "This helped me" star, since even though I already had Paparazzi! he encouraged me to revisit it.
And for the record to help those who might stumble on this thread in the future seeking a solution to the same problem:
The freeware program to get is called "Paparazzi!" and is available directly on the developers site here:
http://derailer.org/paparazzi/
Also, note that the current version only works with 10.6.8 or later, but if you have a previous version of the Mac OS, the developer helpfully maintains an archive of older releases that work with older OS versions -- you can access the old (and new) versions here:
http://derailer.org/paparazzi/downloads
It's also available for free download on various popular third-party sites, like:
http://www.macupdate.com/app/mac/15966/paparazzi!
Be warned that Paparazzi! does not have a very intuitive user interface, nor a user manual, so be patient with it and you should be able to figure out how to make it work.
If you want another application that also does the trick and which has a simpler and better user experience, but you don't mind paying money to buy it, you can purchase and download "SnapWeb" on its developer's site here:
http://www.tribalmedia.com/bts/snapweb/snapweb.html
And if anybody seeing this in the future knows whether or not there is a native way to capture entire Web pages built in to 10.6, please post the info here. Thanks!

Difference b/w eps/jpg/pdf

I work for a newspaper and for several months we have had sporadic issues when it comes to making our plates for the press. By issues, I mean those including pages that suddenly print upside down with the text appearing backwards and other instances where the text and images on a page are partially cut off or jagged.
Today I pin pointed the issue, discovering it had to do with the way some of our advertisements are being made in house.
It appears that when our ad designers go to a third party image site (Creative Outlet, which we subscribe to), they are sometimes downloading entire ads (which include several .eps files) and then pulling one piece of artwork from the ad to use in an entirely different ad.
I was able to locate a particular piece of said artwork that was utilized in one of our ads this past week. It was a .eps. I, instead, re-saved it as a .jpg, then relinked the file in Indesign, where our in-house ad had been built. I then exported as a .pdf and then placed that .pdf in our newspaper layout and exported the entire document to .pdf.
When we went to "roam" the page/pdf, the page was fine, except this ad did not have this piece of artwork showing.
I then went back and instead of exporting the ad as a .pdf, I exported it to .jpg. I then brought it into our newspaper layout, and exported it to .pdf.
When we roamed this page, the page was fine AND the ad now showed up in its entirety.
So, my question or questions, is/are:
1. What are the differences between .eps and .jpg and why would their distinction have an effect on the RIP process or computer to plate process?
2. What are the differences between .pdf and .jpg and why would their distinction have an effect on the RIP process or computer to plate process?
At the end of this, what I really just want to understand is why did the process I eventually came to (saving .eps file/artwork as .jpg, then after placing it in my ad document, exporting said document as a .jpg) work?

I can give you my non-expert opinion, and I'm sure that if I get something wrong, someone will be along shortly to correct me.
Jpeg (Joint Photographic Experts Group) is a file format that uses a grid of pixels to represent an image, so it's a bitmap format. There are several bitmap formats that make them more or less useful in different circumstances. Because the amount of detail in a bitmap image is dependent upon the number of pixels it has, bitmap images can have very large file sizes.
One way to reduce the file size is through compression. Compression can be done by at least two methods: Lossy and Lossless. With lossless compression, contiguous ranges of same-colored pixels that may be described as white, white, white, white, white, black, black, white, black without compression can be described as 5-whites, 2-blacks, white, black with lossless compression. No data is lost, but the reading device needs to be able to read the compressed data and uncompress it.
The other way is called Lossless, in which groups of similarly-colored pixels are changed to a different color in order to create contiguous areas of same-colored pixels. So, if 100 was black and 0 was white (and numbers in between being shades of gray), you might get something like 100, 0, 100, 48, 49, 47, 48, 49, 100, 0, which when compressed might change to 100, 0, 5-47s, 100, 0, and the detail of the different colors is discarded from the file and lost (therefore, "lossy).
With Jpeg, there is also the matter of areas of high compression leaving visual artifacts, which can be seen in the cat image in the Wikipedia page on Jpegs that I linked to above. Many people feel that jpeg is useful for situations where you need smaller file sizes (like low-capacity cameras and slow-connection web viewing), but are not good for printing where file size may be less of a concern than image quality.
Tiff is a bitmap format that offers lossless LZW compression as an option, and Jpeg offers lossy compression that can be set on a scale from 0 to 12. The lower the number, the more data is lost.
EPS (Encapsulated PostScript) is PostScript code (PostScript was originally designed as a protocol for computers to talk to certain types of laser printers) that has been encapsulated with the addition of extra data in order to allow that code to be used as a graphic format. PostScript data can contain bitmap data as well as Vector data (describing shapes with points and connecting lines and curves rather than a grid of pixels). If an eps contains only bitmap data, there is little reason to save it as eps, because modern workflows don't benefit from anything that eps could add, and other formats are usually recommended instead. Even if you have vector and bitmap data in the same image, eps is considered an older format that is better to avoid. PDF Tiff and PSD (Photoshop Document) are formats that can contain vector data and bitmap data.
So, if your team are using eps files of whole ads, how are they doing it? Are they placing the eps into an image frame and using the frame's edges to crop out the unwanted areas? Are they opening the eps in another program and either cropping or removing parts of the ad and then saving? And if the latter, what editing programs are they using and what file format(s) are they saving as? As far as the images shifting, there could be reasons why it's doing that, but I could only speculate without seeing your files and your workflow, which I can't really do over a forum.

I deleted files coldnt open like .jpg,pdf.part

file name unknown and couldn't open or (didnt realize they may have been important )so like a fool i deleted them .jpg,pdf.part,png,gif,ps exe and so forth now i am afraid these were part of the computers programming.. i am new and am so worried, thought i was cleaning junk what do i do now? trash emptied will i ever know what i deleted?

Hi,
Some Info.
First click anywhere on the Desktop that might be visible around anything you have open.
The word Finder should now appear in the menu bar.
Click and hold this to see the menu and select Preferences.
In the Preferences Window that shows up select Advanced.
Select (Tick the check box) the option to Show All File Extensions.
When this is done all the files on the computer will display their relevant .something ending (Extensions).
So most things in the Application folder will now show ApplicationName.app
In the Pictures Folder you will see different ones (if that is where your Picture files are)
.jpg .tif, .png .gif
Some of these such as .jpg or .gif and .tif are fairly universal meaning many apps can open them
.pdf files can be opened by Preview and Adobe Reader as they are Portable Document Files (PDF) and needs a PDF reader. (they can be a mixture of Picture and Text like a word processing cocument)
You will notice in my Pic I have ones ending in .psd
These are saved from the Photoshop Graphics app.
This leads on to the next point.
Most apps will save Files with an ending that in most cases only they can open.
For instance iChat can be set to Save Transcripts.
these are stored in your Home Folder/Documents/iChats in dated sub folders.
You will find they end in .ichat
TextEdit can save in two formats (file Extensions)
.rtf (Rich Text File) or .txt (Plain Text FIle)
Ususally in a file name there is only one . (dot) before the end.
So the way you wrote .jpg.pdf etc. would not exist (there are of course exceptions)
Double Clicking a file will normally get the App that created it or the nearest thing you have that can open it to Launch and then show you the file. (There are ways to Control which app opens which files but that is another lesson)
If this does not work you can go to the Finder's File Menu and use Open With - which will present you with a list of apps that can open a file. (Often this will include Browsers as they often have Plug-ins that deal with the Pics on web sites - Safari for instance includes a PDF reader)
.js does stand for Javacsript.
This is used on Web sites to help with functionality.
It would be unusual to download this unless you were downloading something for a web site about building web sites.
On most web sites the Javascript is a separate file that the page accesses when needed to do a specific thing. Sometimes though small short exerts of javascript may actually appear on the page (When looked at in Source view).
It is similar with .css (Cascading Style Sheets) that many web sites use to change basic HTML into the layout and colours you want. (Again it would be unusual to download such a file)
If you want to know what created or might open a file search here (Common File Extensions)
I would be cautious about deleting anything that you don't know what it is.
The exception to that would be anything that is in your Downloads Folder or has been placed on the Desktop.
Anything that is in Your Home Folder (the Little House icon) is yours.
However deleting stuff in the Library that is inside there may cause problems with apps running properly.
In may cases the Preferences you set are stored there. In some cases the results of you choices cause other things to be stored that are needed when the app runs.
Deleting things in Documents, Pictures, Movies only deletes things you might want to Keep.
I would also leave iTunes and iPhoto files alone in their relevant places.
If in doubt post and ask. Be clear about where the file is located and what you know about how it got there.

I can't open attachments on my iPad 2t and I can't open jpgs, PDFs, docs. or movie files now.

Obviously, you are talking about the mail app, so force close the mail app and reset your iPad. If that fails, reset all settings.
In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
When you reset all settings, you will not lose any data, but most of the device settings will have to be entered in the settings app again. Settings>General>Reset>Reset all Settings.

Is it possible to import a pdf instead of a jpg to put in the base "photo layer?"

Is it possible to import a pdf instead of a jpg to put in the base "photo layer?"
I start with a pdf document convert it to a jpg
     mark it up in ideas
     then finish up with a marked up jpg document
     then reconvert it back to a pdf
I can only use jpgs in ideas. Converting the pdf to a jpg and them re convert it back after marking it up but this seems like an awfully round about way of doing things especially as it should all be inhouse adobe products .
An alternative would be to use adobe reader to mark up the document, but this does not allow me enough control as compared with marking it up Ideas, particularly with layers and control of the tools.
What I am trying to do is mark up and scribble over my architectual CAD drawings which are exported as a pdf document.
Any one got any bright ideas?
thanks

Hi Brian,
Saving as PDF it is not currently possible.I created the following feature request on your behalf. Please add your vote and any comments you would like see included
http://forums.adobe.com/ideas/1973
I also considered recommending Adobe Debut, it is currently only available on Android and might only work if you presenting the markup data from the tablet itself. You can import a multi-page PDF and add markups to the various pages and present the document to someone from the tablet, not sure if that would be useful for you or not?

System or Safari renaming .jpg to .jpg.pdf and pictureviewer fails

Hello all.
When using webmail (on Safari 2) I ran into this:
File attachments using .jpg extension is being downloaded and renamed to .jpg.pdf when clicked on. The file gets downloaded to desktop and when pictureviewer trys to open it it fails, as the file is not pdf.
Any suggestions?
Yours Sincerely
Martin

Hello andyball_uk
Thankyou for your advise. I do agree that the problem on the server end and when trying to ctrl-alt click on the link I get a Download.php file. THe webmails Costumer service basically told me to f* o** since they didnt and wouldnt support OSX.
But i found another workaround:
Since my OS is the danish version some translations might be wrong, pls correct if so.
Created Download folder on desktop, set Safari to use that as a download folder. Unchecked "Open safe files..:" too. the file now saves in that folder.
Created an Automater workflow who is to rename finder items from .jpg.pdf to .jpg. AND then open finder item.
Saved as accessory to foldercommands, applied the folder and voila.
Its works.
Thx for the reply, I consider this solved.

Email attachments download as ashx for Microsoft Outlook, instead of jpg, pdf, doc, etc. Tried to fix in Preferences Applications but still doesn't work.

Using MacBook Pro running 10.5.8. Downloaded Firefox 8 on 11/9/11 and now Microsoft Outlook Web App 2010 downloads all email attachments as "attachment.ashx" instead of jpg, pdf, etc. This was not a problem with previous Firefox releases which I've been using for the past couple of years. Can open files if I edit the extension to the proper variety (ashx to jpg for example), but no longer initially automatically opens. Instead I first get a "can't open this file" message. Attempted to fix in Firefox > Preferences > Applications by indicating the proper "Actions" for various "Content Types" but this had no effect. Chrome and Safari browsers still work properly. How can I fix this?
