Reduce file size of image a user loads into image field in form

Hello,
I'm a Mediadesigner from Germany and I started to work with Lifcycle Designer about a year ago.
I already made some smaller forms with different fields.
Now I have a special form with empty image fields, that allow the user to put in his images.
For the form goes out to so many different people, some of them just take the images as they are, load them into the form and so the filesize of the pdf grows. For your information: the filled out pdf will be sent back to us by e-mail.
So here is my question: is it possible to reduce the filesize of that images when it is loaded into the fild or when the filled in form is saved.
For example that I can say: "Take all images and make them 72dpi and max. height 500px"?
Thanks for your help in advance!

Hi,
there is now way to reduce the real file size or dimension of an imported image.
But you can checkt the file size and show a warning to the users to use a smaller file.
Here's a sample which describes how to do so:

Reduce File Size causes images to be blurry

I created a document in Pages '09 that contains several masked images, resulting in a really large file size. I clicked Reduce File Size to get rid of the cropped parts of the images. Unfortunately, the images are now blurry. Any way to mask or crop a picture, or use Reduce File Size, without loss of image quality?

The images are being reduced to 72dpi with no sharpening that I can see and the excess image outside the masking shape doesn't seem to get trimmed. I suspect you then saved to a pdf with a lower quality setting which would have given a 2nd reduction in quality on top of the first.
So the best option is to take your images into Preview, crop them, reduce their resolution and sharpen them then bring them back into your Pages layout before exporting to pdf.

Reducing file sizes going from LR to PS

Hi - just wondering how to reduce file sizes when I edit from LR4 into PS 5.
I was working on some jpg files and they are around 5mb but when I open them in PS it shows them to be 50mb. ... Just wondering why and how to open them so they are not 10 times bigger?
Thanks
Rob

What Dde said. I'll add that if you have a new camera supported in ACR 7 or 8 that isn't in ACR 6, I think "Open Anyway" will open Photoshop if it's not already open, but then might not do anything after that becaus PS/ACR can't open the raw file. Figured that out after a lot of confusion about why Photoshop just sat there.

Images load really slow after using Reduce File Size...

After using the "Reduce File Size..." feature in Acrobat 9 on Windows Vista, some of the images load really slow as I page through the document. Is there some kind of compression setting that I should look for to prevent the images from be affected by this?
For some of my documents it will take 30 to 60 seconds to load an image. Sometimes I can't do anything with the document until the graphic loads entirely.

Can you post an example of a file that has this issue? Personally, I recommend using the PDF optimizer, it gives better control of the final pdf file.

Reduce File Size in Acrobat Pro (9.5.5) Corrupts Graphics in PDF Documents - shows up as black image

Whenever I use Reduce File Size in Acrobat Pro (9.5.5), sometimes some of the images (not all) get corrupted and show up as a black image in the new document.
Actually, the new reduced document looks okay when viewed in Acrobat, but the problem shows up when viewed in the Preview application on the Mac.
I'm using Acrobat 9.5.5 with Mac OS 10.8.6
I've tried re-importing the graphic into a new graphic box, which didn't work. Thinking there may be some type of corruption with the actual graphic file, I then tried viewing the graphic, then taking a screenshot of it to create a completely new file, and then re-importing the new graphic file into the original document (created in Adobe In Design 5.0.4). I then export the new document as a pdf, and brought it into Acrobat Pro to do the Reduce File Size. Same thing happens - black box appears where the graphic was.
I then tried using the Reduce File Size within the Save As function of the Preview application on the Mac - while the graphic remains intact, many of the other graphics in the document are "reduced" too much, to the point where the image quality is seriously degraded, and therefore not usable.
Any other ideas?

Hi Anoop,
I can share the graphic file, but not the pdf which contains it (as it contains confidential information) - thanks!

Reduce file size w/o blurring up my images?

I have a Pages (iWork '09) document with a lot of images (screenshots) in it. Many of these are large shots where I've used the mask option to hide what I don't need. The file is pretty large, even when I export it to PDF. Using the Reduce File Size option turns my screenshots into a blurry mess. Is there are way to get rid of the cropped areas w/o mucking with the image resolutions? Most of the pics were screenshots from Evernote dropped into the Pages file.
Short of that, will exporting to PDF and using Adobe Acrobat Pro's file optimization do the trick w/o blurring things up too badly?

Thanks for that. I was hoping I had independent control of cropping. I'll just have to do the cropping manually and rely on masking for trimming out little bits of things. I'm coming to Pages after years with Word, which allows more control when it comes to dumbing down images. I really like composing things in Pages. Now I just have to learn the best ways to get quality output w/o huge file sizes.
Thanks,
Wheat

Trying to reduce file size of my opening page in a flash site

I'm using the Flash CS4 IDE, and the first page of my site takes a lot longer to load than I want it to. So I wanted to go through the varied images / symbols / movie clips / sounds and so on to see where all the memory is being chewed up.
When I go into my library, however, I can see the Name, LInkage, usecound and Type of my elements, but no mention of file size and I can't seem to find any right click menu that lets me add file size to the list of details being displayed.
Is there a way to make it show file size? Or some workaround?
And are there any best practices to reduce file size aside from using symbols for anything that's used more than once and reducing image and sound quality?
Thanks

I was actually using the term pretty loosely. I'm building a Gaia site which works by loading an Index page, then a Nav (navigation) page on top of that, and then lets you load and unload pages as necessary on top of those.
Since the Nav page never gets unloaded it's a good place to park certain content. So it's actually my Nav page that's gotten too bloated. And the coding is handled through a separate Nav.as file (so it's not the first frame of my nav.swf, it's all the varied movie clips I had to incorporate into my Nav.fla
I'm just looking for a way to identify which MovieClips & sound files (only have a couple of short ones) and other assets are taking up the most memory so I can see if I can cut those down.
Also, do unused symbols use up memory or is it only the assets you actually end up adding that count toward file size?
Thanks

Reduce file size of Movie Clip

My swf file is 1.3 MB. It contains a dozen 72dpi images with
alpha tweening. It is taking awhile to load. Is there a process to
follow of a free software to reduce the file size?

The proper way to reduce file size is keep your images
external and load
them on demand.

Reduce file size with action wizard

(German version below)
Hey,
I got two questions for action wizard in Acrobat XI Pro.
I try to reduze file size of many PDFs using acion wizard. My tests worked fine but now I got some problems I try to explain now:
1. I add a directory with many subdirectorys to my process list. Adobe now adds not only PDFs to my list, it also adds JPGs, DOCs etc. That means I have to delete every single file I not want to convert to PDF cause I only want to reduce file size of excisting PDFs. Is there any possibility to only add PDFs in my processing list?
2. If a PDF is opend by any other user I get a information about it. This info I need to acknowledge every time it pops up cause my process interrups. Is there any possibility to ignore this info?
I´m happy for any help i can get here. Thx.
Regards
(Sorry for bad english, it´s not my favorite language )
Hallo Leute,
ich benötige Hilfe beim Benutzen des Aktionsassistenten im Acrobat XI Pro.
Ich versuche bei sehr vielen PDFs die Dateigröße zu verringern. Dazu habe ich mir eine Stapelverarbeitung per Aktionsassistent erstellt die bei meiner Testumgebung auch super funktioniert. Leider habe ich noch einige Probleme für die ich Hilfe benötige:
1. Wenn ich einen Ordner mit sehr vielen Unterordnern und verschiedenen Inhalten einfüge möchte ich eigentlich nur die PDFs verarbeiten. Leider fügt Acrobat auch alle JPGs DOCs etc. hinzu. Ich muss also alle unerwünschten Dokumente herausfiltern, da auch keine sortierung vorhanden ist. Bei mehreren Tausend Dokumenten nicht leistbar. Gibt es hier eine Möglichkeit nur PDFs in die Stapelverabeitung aufzunehmen?
2. Sollte die Verarbeitung mal laufen kommt es hin und wieder vor das die PDFs durch einen Benutzer geöffnet sind. Ich bekommen hier eine Meldung von Acrobat die ich erst bestätigen muss bevor es weiter geht. Da das Programm eigentlich über mehrer Tage/Wochen im Hintergrund laufen soll passt mir das gar nicht wenn ich alle Stunde überprüfen muss ob die Stapelverabeitung noch läuft.
Ich hoffe es gibt jemanden der mir helfen kann. Ich bin über jede hilfreiche Antwort glücklich.
Gruß

For starters, let's refer to your original post: "this is indeed a serious problem and step back in functionality..." This statement is a quite ridiculous assertion, unnecessarily dramatic, wholly inaccurate, and unhelpful. Your statement "is this a joke" and "I know Acrobat tends to choke...etc..." is just pure gibberish and polemical. It is quite easy to feed any application enough data to cause a performance failure, but one would really need to question one's motive and prudent use of one's time at this point - unless you are tasked with stress and load testing the software to determine minimum working requirements.
'Batch Processing' is, since Acrobat 9.x, dead and gone, Acrobat 11's approach is to aggregate many hitherto unavailable tools and commands and allow the user to create custom workflows. More interactivity has been built into the process, which may or may not be desirable in each case depending on the workflow context and requirements. But we have obviously moved away from the concept of processing a large number of files and towards a more targeted and effective processing of smaller sets of files. The default Actions we deliver with Acrobat 11 reflect this intention.
The feature "Batch Processing", which was an Acrobat feature from A5 (I believe) up to A9, previously had been hidden in Menu/Advanced/Document Processing/Batch Processing has been wholly replaced by a completely overhauled framework called Actions, now part of the Tools panel, and will be immediately accessible when Tools is called in the UI.
Thus the obscured Batch Processing may have been a tool considered and used by an extremely small set of users to do exactly that, i.e., batch process a large number of files, but had been fairly inflexible, generally speaking, and buggy. We were very well aware that if we were to overhaul the feature, add a considerably larger number of available tools and commands in Acrobat, provide wide possibilities for customization built towards specific workflows, and bring it to the forefront, we were going to sacrifice some of the aspects of batch processing a large number of files. Not calling it "Batch Processing" anymore - because it isn't - may be an indication of this intention.
Personally I have used and tested Batch Processing periodically during various Acrobat projects, but I don't remember encountering the "Reduce File Size" command - which is a subset of Save and file optimization - to use within a batch sequence. I may be wrong, and your screen shots would be welcome here. In fact go ahead and construct a batch sequence that (1) uses 'Reduce File Size and (2) applies file type filters to it, and post it either here or to me privately. I would be happy to be wrong. But regardless, we are grateful for positive input that points out defects, allows us to improve the functionality of the product, providing the intended changes are reasonable, and that the communication of said issues remain respectful of this process and of the individuals we depend upon to implement these changes. The tone of your response comes very close to rendering a proper consideration of this issue irrelevant.

Reduce File Size Crash

One of our G5 iMacs has a problem with running Reduce FIle Size in Acrobat Pro 7.0.9 and crashes every time. We've tried different compatibility, but each time it starts working on the images within the pdf, boom!
I've tried re-installing Acrobat with the same results. The full CS2 suite is installed, are there any user level prefs I can trash? Any help would be appreciated... thanks!

The G4 Macs at my school had the same problem, until they upgraded to CS3. I think it was probably a bug in Acrobat 7... have you installed all the latest updates? Check the updates section in Adobe downloads, all the updates for CS2 are still available. If that doesn't solve the problem, I would suggest upgrading to Acrobat 8, or CS3 if possible.

Why is "Reduce File Size" in the "File" menu always disabled?

I have a rather large presentation file, about 100Mbyte, and Keynote has become almost impossible to use, because it has become so slow.
Have to wait about 5 seconds for each letter to appear on screen after typing! Almost impossible to use Keynote under these conditions.
So I tried to use "Reduce File Size" to reduce the presentation file size by compressing the images, but "Reduce File Size" is always disabled!
Anybody else having such problems?
Gerhard

OK, sounds like memory will be fine, so let's look at some other stuff...
Is it only one particularly keynote presentation that slows up for you, or does keynote behave in the same way even if you start from scratch and create a new presentation?
If it's just the one presentation then there's probably some content (possibly video) within it that KN takes exception to. Sometimes a single problematic slide or piece of content can slow down the whole app.
Is the problematic presentation one that was imported from Powerpoint? If so, import it again and look carefully at the import error/warning logs.
Before you start keynote, start up activity monitor - which will give you an indication of what programs are using all the CPU/memory/disk bandwidth etc. You'll then have an idea of whether it is KN maxing out on CPU or whether anything else is dragging the system down.
Another thing you could try would be to log in to a different user account on your machine (create one if necessary) and then try opening the presentation from within this different account. If this works for you then it suggests a problem with the keynote plist file in your original user account.
I don't know if it'd be acceptable to you, but if you could post a link to your problematic presentation then I could download it and try it out on my normally reliable Keynote on one of my computers. (Make sure that you've ticked the box to embed all media in the presentation)
Hope some of this is helpful,
Mike.

Ways of reducing file size??

Hello,
I have a 3D animation that is rendered to bmp frames.
I have inserted the animations into a Flash doc.
After editing, my final Flash movie/file is 20MB.
what are the best ways of reducing or compressing the file size down to a resonable "web-ready" level? Around 8MB or lower?
I want to avoid lowering the quality from 75%.
Please advise, thanks!
D_xyz

The primary way to reduce file size is to reduce the size of the imported content that the file is holding, meaning images and sound elements. The ways to reduce the size of those things is to either optimize them before bringing them into the Flash file, or loading them dynamically so that they are not part of the published file's weight.
In your Flash Publish Settings you can select the option to "Generate Size Report" HAving that report you can see the contributions of each piece to the overall file size, and in turn focus on them to try to bring the size of the file down.

Reducing file size on multiple photos

I up load my photos for prints. Most of my photos are 2+ mb in file size so when I am up loading a group of photos for prints it takes an hour or so at a time. Is there a way in Elements 4.o to reduce the file size of multiple photos simultaneously for up load without over writing the original image?
I'm willing to save a copy of the images in the reduced file size that I could delete after up loading, but would love to find a way to reduce the file size on multiple images instead of "Save as" on each image.
Any thought would be appreciated.

Good evening
Process multiple files (under File) should do what you want-you can select files from a folder, send them to a new folder (to save the originals), adjust size and quality. The pop up window is fairly straight forward, but post back if you have any questions.

Reducing file size #2...Preview, Quartz Filter vs Adobe Pro Optimize

Questions on reducing a pages to pdf file…I will post each question seperatly.
2) I read that you can reduce file size of a pdf in preview with a quartz filter. I created my own filer and it worked as expected. But, I also have Adobe Acrobat Pro, with save as PDF Optimized. The pro seems to have much more capability than the quartz filters.
Is one better that the other to use? The adobe optimize (standard settings) took it from 20 to 6 megs.
THanks, Bob

The Adobe Acrobat settings you chose are probably using .jpeg to reduce the file size.
.jpegs are lossy. ie You lose detail and sharpness the more you compress the image.
The Quartz filters are usually of very high quality, but they are a black box and you need to understand what the settings are in each one. Quartz filters are extremely powerful, fast and as I said usually high quality but I suggest you experiment and see if they meet your needs.

How do you reduce file size of a PDF if Save As doesnt work?

I have been trying to reduce the size of a PDF, using the Save As > Optimized PDF method.
I have also tried Save As > Reduced Size PDF.
This is on a file made up of 20 pages of full page Jpegs. (These were generated by the script in Photoshop that generates Jpeg files from Layer Comps within the document.)
If I use Reduced Size PDF, I get a greatly reduced file size but the image quality suffers greatly. (Lots of artifacts and blurryness)
There are no options to choose the level of compression I want.
If I use Optimized PDF method, I cant seem to reduce the file size no matter what I set the Jpeg compression to.
Is there some way to cut the size of the file down but not lose so much image quality?
Any suggestions?

Part of the problem here is that the files that are produced when I run the script to output files from layer comps are very big.
If I "save for web" for each layer comp, I wind up with way smaller Jpegs. Thus a much smaller PDF.
So the question is: Can you make the script, Layer Comps to Files, create smaller more optimized Jpegs? (Like you get when you save for web)
