Why are Preview saved file sizes so HUGE?

We have a neat copier at work that will scan in a document and email the pdf to you. So I have a 100 page document that I scanned in 4 chunks that yielded 4 pdf files of about 2.5MB each. I opened the first in Preview and then dragged the remaining 3 files in to create my final 100 page document. When I did the Save command I was shocked to see the resultant file size came in at 27MB! I searched around the menus and tried a Save As and selected the option for just black and white. The file that was created when that command finished ended up being 67MB.
Anybody know how I can just get the originally expected 10MB file size? Many thanks in advance.

I just tried the Combine PDFs program and it also yielded a 27MB file size when the sum of all the input files was only 10MB. So now I'm really confused. If I had to take a guess, I'd say the pdf format supports some kind of compression and both Preview and Combine PDFs can read in compressed pdfs but can't write them. I still need to get down to the 10MB size (because I can't email the file 27MB size I ended up with) so I'm still looking for help.

Why are my saved files now xmp?

I'm using elements 10. I've been uploading to picasa, editing in elements, saving a psd file to picasa, then exporting to a folder as a jpeg. As of last night, my saved files are now xmp??? and are useless to me. I don't know what happened??? Please help me. Thank you so much!

PSE does not save your images as .xmp. Your images shoud still be there, in their original format.
These .xmp files are placed there for other reasons, usually when you edit RAW files in PSE/ACR.

Why are my QT file sizes shrinking?

I'm using the copy/paste features of QuickTime to put together four small pieces of my movie into one big piece. I do this by opening up all four QT files and then copying the entire contents of each of the final three QT files and pasting them all, one at a time, end to end, into the first QT file.
Here's the situation: all four pieces are about 300mb each; yet when I save the master file, the result is usually around 300mb.
In other words, there seems to be some data DISAPPEARING in the process. But when I open up the resulting big file, full screen size, and compare it side by side, to the original files, I see no image quality lost. Frame for frame.
I've repeated this process several times. Same result.
How can 3 + 3 + 3 + 3 = 3 ?
Shanked
PS the resulting file plays fine. The only reason I'm posting this "problem" is that I'm having repeated failure trying to upload my movie to IMDb's withoutabox website.

Thanks QuickTimeKirk,
I guess this is a big "duh" for me. I actually had thought I had been toggling that choice all along, because, frankly, it's the ONLY choice that comes up when trying to save. But for whatever reason, the file hadn't been saving that way, as in self-contained.
much obliged for your help!

When I narrate my keynote presentation, why is the file size so huge?

When I narrate my keynote presentation, why is the file size so huge?

Here are the steps so you can see all the files that make up your Keynote…
Go to the Finder and find your Keynote file and make sure that it has the .key extension on it. If it doesn't, click it and command i to view info and uncheck the box that says Hide Extension.
Delete the .key and change to .zip and then click the use .zip in the dialog box that comes up
Double click the new .zip file and it will change it to a folder
Open the folder there are the files
Close the folder and add .key to the end of the name and click Add in the dialog box (this will change it back to a Keynote file)
You might be able to do this and convert the voice narration to a smaller format.

Safari, "Private Browsing" - why are cookies saved?

I normally use Private Browsing out of habit on all my computers using Safari but I do have a few questions on it -
Why are cookies saved even when "private browsing"? go to one genealogy site that requires membership and the cookies from that site are always present in my cache. Are pages also being saved in the page cache as well?
What is so "private" if info can be assembled?

Saved file size decreases with time

Hi all,
I am using Data acquisition system with rate 10000 and 1000 sample per channel (exist 4 channels) to acquire analog voltage signals to measure the amplitude in each channel.
Moreover the raw signals are saved as TDM file of 1 minute. The system is running continuously for one week. I noticed that after 3 hours the saved file size is decreased as a function of time.
The size starts with 50 MB/min and after 3hours it became 42MB/min, after 1 day became 11MB/min. That indicated the data was lost , please, what is my programing mistake.
Thanks
Solved!

From the State Zero code, there are several things that could be improved here.
1. You only need to create the task once before your main loop.
2. You probably do not even need the outter loop if you use the DAQmx Configure Logging like I have already stated. And you can use properties to say how many samples to go into a file before moving on, so that part of your code is eliminated.
3. The display can just be a simple chart (it looks like you are probably already using a chart).
What is your chart history set for? That could be causing your slowdown if there are too many data points.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Why are ACR PSD files 10-20 percent larger than the same file resaved in PSD?

Why are ACR > PSD files 10-20 percent larger than the same file resaved in PSD? I posted this many years ago and never found an answer. Now that my drives fill up quicker, I thought I might chase this question a little bit further.
Same .CR2 saved within ACR either with cmd-R or open ACR within PSD, the saved file is 34.5mb. Resave that same file (no edits) within PSD either with or without Max-compatible and the file is now 30.7mb. Another file that is 24.5 becomes 19.5MB.
Why the difference? Is ACR and PSD actually using different compression strategies?
thanks.
Mac 10.8.5 / CC / ACR 8.4.1 - but this has been a consistent behavior over many years and versions, CS6 / CC.

Hi Jeff
If it is RLE it's not as efficient as LZW:
Saved ACR>PSD = 40.1MB (sample image this AM)
opened in PS and resaved as PSD = 30.8MB
resaved as TIF without LZW = 40.1MB (this adds to your thought that the ACR>PSD doesn't us any compression)
resaved as TIF/LZW = 9.6MB

??? I hope that the Adobe engineers are fussing over 10-20% efficiencies.
I'm within arms reach to a rack of 40TB of drives (doesn't include off-site drives), and all 2TB drives are being recycled to 4TB drives, as a result the rack is always growing. Actually the ACR>PSD files don't really make a difference in our long term storage, only for the nightly backups. But anyway, how you save, what you save etc. should all be part of the discussion.
.... so in my case, throw in an excess MB here and there and all of a sudden you are talking TB's. Plus advantages in backup times, drive life, and energy use.
Somebody added compression into the PS>PSD format, but it wasn't included in the ACR>PSD format, was it a decision or an oversight? If it's just a matter of making ACR compatible with PS when saving the same PSD format..... then why not?

For the Receipts app I chose to export the info as a PDF file..an email was requested..I entered info and clicked send. For the Business Card app I chose Send, not Print..an email was requested..I entered info and clicked send. I haven't received anything, not even in my spam folder.

Why doesn't flash player stay installed and why does the saved file disappear.

Why doesn't flash player stay installed and why does the saved file disappear. I have downloaded and installed flash player several times on my Win7 Vaio laptop. I have uninstalled and deleted all versions. I am the administrator and I have also turned off my Security Software, but the same thing keeps happening over and over. The Java Script is enabled and I have tried both downloading via IE and firefox. It is rediculous that it keeps disappearing and I keep getting messages that the newest version is needed. I am downloading directly from adobe and they say it is the latest. Getting very frustrated. They ask if we have any problems when we go to the finish line, but there is no place for comments. I guess they don't really care if it works or not.

So is it actually installed, or is it not? If not, download and run the offline installers:
Flash Player for ActiveX (Internet Explorer)
Flash Player Plug-in (All other browsers)
If it still does not work correctly, check

In Firefox also check if the Shockwave Flash plugin is enabled.

PS CS6-Why are file sizes so huge?

My psd's are almost double the size as compared to similar files created from CS5. There are no vector objects, no huge amount of layers as compared to my older files and not a lot of visual information. It seems that a text layer consisting of 6 letters is about 3MB. I've turned of Autosave and Background saving in preferences. It doesn't seem to matter.

Maximize PSD and PSB Compatibility >> Never
(from Adobe Help)
Maximize compatibility for PSD and PSB files
If you work with PSD and PSB files in older versions of Photoshop or applications that don’t support layers, you can add a flattened version of the image to the saved file.
Note: If you save an image in an earlier version of Photoshop, features that version doesn’t support are discarded.
Choose Edit > Preferences > File Handling (Windows) or Photoshop > Preferences > File Handling (Mac OS).
From the Maximize PSD and PSB File Compatibility menu, choose any of the following:
Always
Saves a composite (flattened) image along with the layers of your document.
Ask
Asks whether to maximize compatibility when you save.
Never
Saves only a layered image.

Does anyone know why I get varying file sizes when I save a jpg (with same settings-None, 12, base "standard", preview checked) from PhotoshopCS5?

I opened a .psd file (300 ppi, CMYK, .jpgs (1626px x 2130px), I saved it as a jpg (None, 12, base "standard", preview checked).
I then closed the original .psd file.
I repeated those steps on the same file and saved a series of 6 .jpgs.
Of those 6 files, I received 2 large files (6.2MB) and 4 smaller (3.2MB) files.
My coworkers who were having trouble opening some of my jpg images in Windows Photo Gallery on Vista OS were able to open the smaller files but not the larger ones.
Do you have any idea why the same settings would give me different file sizes from CS5?
Is there a way I can make it consistently keep the smaller more compatible version?

How well a image data compresses depends on image content. Image with High detail do not compress well image will little detail will compress well and the file size will be small. Compare a image of a blank white wall to a wall with a black and white checker board wall paper. One is all white it white no other detail to detail the other has squares that vary in size because of perspective angle and distance a lot of detail must be recorded.
I do not know why they can not open some of your images. File size should not be an issue. All your image decoded are the same size Width number of Pixels Height numbers of pixels background layer only for these are jpeg files.

Why are my Jpg files so small after being saved from Nef

Hi,
I am finally posting after months of trying to figure out why my images are saving so small, some 4mb after converting from Nef to Jpg.
I am shooting with a Nikon D4s and came from a D800. I was spoilt with really large file sizes and now I am freaking out because my jpegs are so small.
I am checking all the right boxes as far as I can see to save the jpg as large as I can, and I am not cropping the images before saving as Jpg.
Has anyone else had this problem? I can't understand why a camera as amazing as the D4s is giving me such small files. I have read everywhere that my files need to be over 6mb to be classed as high res.
The only thing that I can think of is maybe I am pushing my nefs too hard in camera raw/lightroom resulting in a loss of quality? Although my exposure is correct 90% of the time so Im only playing with highlights or luminance.
Can anyone walk me through the process of what I should be doing so I can end this headache!
Thanks in advance!

Images are 16pm (4928x3280px as you say), and the doc is 48mb.
So here's where I really show myself up... am I right in assuming that the more adobe compresses an image the lower the mb is on the final file, meaning if there is less detail (i.e. the low-key image is predominately black) then the jpeg will be smaller. Does this affect the print quality?
4mb seems very low res to me. How can I retain as much of the information as possible? Do you think I should sharpen more to retain detail? Or does it even matter and I'm fretting over nothing!
Okay. The file dimensions are fine, so we're talking purely about content and compression.
As I already said, the low-key image contains very little data in the first place (lots of black and no colour), so it compresses well. The dreamy woman image contains a lot of plain blue sky and out-of-focus background, so that compresses well too. No surprises there.
Have you got any more detailed images with greater depth of field? Try creating a JPEG of that and see how big the file is.
An Adobe JPEG Quality setting of 12 means minimum compression and therefore maximum file size. But, even so, if you saved an image which was just a single plain colour, you would find that the resulting JPEG would be just a few kB. This is how compression works.
The lower the quality number is set, the higher the compression, the more detail is lost, and the more JPEG artefacts are created in the image. You are already saving at 12 quality, which is the highest setting, so you are minimising any problems with detail. You should save as TIFF if you want absolutely no loss of detail, but the file sizes are much bigger.
4MB is not a resolution. Think of it as packing a suitcase. If you're taking lots of books, you won't get the lid down. If you're taking lots of soft woollen sweaters, you can take lots. 4MB is an indication of the space that your packed image takes—if it's made of light fluffy stuff then it will be a smaller suitcase! :-)
You should sharpen your images the same as any other. Large areas of plain or out-of-focus background need not be sharpened. You're okay. Stop worrying!
