PDF file size after merging

I use Preview to merge PDF files. I have noticed that the resulting files are a lot larger than the sum of the single PDFs. An example: I have 3 files with the following file sizes: 70 KB, 120 KB, 1.3 MB. The resulting PDF after merging those files in one is over 5 MB.
Does anyone know why this is the case and how I can avoid it?
Any help is highly appreciated!
Tobias

Yes, I also have this problem.
Several PDFs with a combined size of ~13 MB, when merged are over 40 MB, making it unsendable by e-mail.
Very annoying!
This results from using Preview's "drag and drop" onto the sidebar to merge PDFs. DOn't know why.

PDF Files Size after Scan

I have a Canon MX892 (made for personal use) all in one printer in my home, when I scanned a 21 page document it turned out to be 14 meg in size. I scanned this same document from my office which has Konica C54 all in one printer (made for business use) and the file size was 6 meg.
Is there any way that I can reduce the size of files that I scan at home? I have Adobe Acrobat XI Pro and tried saving it "optimized" and it only reduced the file from 14 meg to 13 meg.
I would appreciate any advice you might have.

Hi gold154,
You might also try Acrobat XI Pro's specific feature for optimizing scanned documents. This often reduces the file size on my scanned files.

Preview.app increases PDF file size after deleting pages

Hello, I'm experiencing odd behavior with Preview.app and PDFs.
If I open a PDF with Preview, delete a page, then save the file, the file size increases anywhere form 2x to 20x. This happens both with PDFs that only contain text and PDFs that contain text and graphics. It is very frustrating because I start with a file that is 150KB, remove some pages and end up with a 10MB monster that I can't email to people.
Any help is appreciated. I can post a link to a test PDF for people to try to replicate with if it would be useful.

I generated the file with pdftex. I'm guessing that there must be different ways to encode a PDF and when Preview gets something with an encoding other than that provided by PDFKit, it rewrites the file how it likes. In my case this is increasing the file sizes. I tried finding docs about PDFKit on the Apple developer site, but couldn't find any details about ways of encoding a PDF.

Using Examine Document Remove increases pdf file size !

Hi,
I have Adobe Acrobat Pro v9.3.0
I've been editing a lot of scanned .pdfs - rotating and cropping pages.
All this has previously worked fine with v8 but now I find that Acrobat 9 is increasing the .pdf file size after using Examine Document and clicking Remove
For example:
original file: 16,861 Kbytes
file after cropping 74 pages (from A4 to A5): 16,879 Kbytes
file after running Examine Document > Remove cropped metadata : 79,914 Kbytes !!!
With Acrobat 8 this process would normally have halved the file size.
Am I now doing something wrong ??
Thanks in advance.

Hello - This problem is still here !
Acrobat 9 Pro version 9.4.2
I've got a .pdf created by an agency (so not a scanned image) which I want to make as small as possible for emailing to hundreds of people (I'll attach it if possible somehow ?)
I open it up when it's 331Kb
Click Document > Examine Document
Check the Metadata and Deleted/Cropped items
Click Remove
Click File > Save As and hey presto, the new file with all that stuff supposedly removed is 2,588 Kb
Surely I'm not the only one who's bothered about .pdf file size ?

PDF file size

I have an HP Officejet 6500 E710n-z (Network) that I use at home to scan into PDFs, and I know exactly how to move the slider from "Smallest size" to "Best quality"
However the size of the PDFs are unacceptably large when image quality is acceptable, and if I move the slider to reduce the size then the image becomes unacceptable. It is impossible to scan a legal document of more than a few legible pages without producing a file size too large to email . I am forced to break these scanned documents into 3-4 page bite-sized chunks.
A simple one page HOA Disclosure form, at 220 DPI and the slider in the middle for balance, produces a 699K PDF. I have used other printer scanners at work (different brands) at the same 200 DPI that results in very clear documents at less than 100K per page.
I believe there is something wrong with HP's scan-to-PDF algorithm. The problem must be due to some unskilled (or flawed) software design. What will it take to have HP or third party developer (and developer staff supervision) take this seriously -- compare HP vs other brand scanners PDF files -- and update the HP drivers to fix this?
This question was solved.
View Solution.

Just a follow up. I went into chat mode with some low-level tech named Nathan, giving him the link to this thread. After reading it, he suggested I can improve file size by using greyscale and 200 DPI. DUH!!!! I complained he was just humoring me, so he said I should call the tech support number.
I did that next and spoke with a very nice young lady who actually DID take me seriously. I could hear her typing away vigorously in the background, capturing every detail of my plea for this to be forwarded up the chain of command for serious consideration. It was clear she understood and captured from me that there are many forum complaints that can be found with a search term "PDF File Size" that are getting weak or unacceptable "solutions" to push the slider left or use lower DPI etc. She also captured my assurances that some competitor brands produce PDF file sizes 20 times smaller for the same image quality.
I believe that this might actually be opened up at a higher level for consideration of an improvement in the compression algorithm. My fingers are crossed. Since I have about 11 months left for warranty support, I plan to contact them once or twice again before it expires, using the same case number to see if there is any progress.
Bottom line: At my default of 200 DPI and 20% image quality, with an average file size for a single sample page producing a file size of 281KB, a 25-page document creates a PDF file that is 7MB! That will just barely make it past the file size limit for my email provider, but might be too large for the recipient. That is still unacceptable, and is forcing me to consider products other than HP for this business purpose.

PDF File Size Problem

Hi,
I am using Adobe Acrobat Elements 7.0 in my computer to convert files like .txt and .doc to .pdf files. But currently I'm facing a problem with the converted .pdf file size. For example, my .doc file is 5MB and after I convert to a .pdf file, it becomes 10MB. The file size basically multiplies itself by 2.
I've tried converting .txt and .doc files and it gives me the same problem. I've tried reinstalling, tried all kinds of settings, and recreating user profile but it doesn't help. Can anyone help me? Thank you very much.

Sorry. The problem is caused when I want to password protect a .pdf using elements. So I used Adobe Reader to open the .pdf file then I'll print using Adobe Printer so that I can password protect it and output file size is actually 10 times the normal .pdf file.
Please help!!

Large PDF file sizes when exporting from InDesign

Hi,
I was wondering if anyone knew why some PDF file sizes are so large when exporting from ID.
I create black and white user manuals with ID CS3. We post these online, so I try to get the file size down as much as possible.
There is only one .psd image in each manual. The content does not have any photographs, just Illustrator .eps diagrams and line drawings. I am trying to figure out why some PDF file sizes are so large.
Also, why the file sizes are so different.
For example, I have one ID document that is 3MB.
Exporting it at the smallest file size, the PDF file comes out at 2MB.
Then I have another ID document that is 10MB.
Exporting to PDF is 2MB (the same size as the smaller ID document)... this one has many more .eps's in it and a lot more pages.
Then I have another one that the ID size is 8MB and the PDF is 6MBwhy is this one so much larger than the 10MB ID document?
Any ideas on why this is happening and/or how I can reduce the file size.
I've tried adjusting the export compression and other settings but that didn't work.
I also tried to reduce them after the fact in Acrobat to see what would happen, but it doesn't reduce it all that much.
Thanks for any help,
Cathy

> Though, the sizes of the .eps's are only about 100K to 200K in size and they are linked, not embedded.
But they're embedded in the PDF.
> It's just strange though because our marketing department as an 80 page full color catalog that, when exported it is only 5MB. Their ID document uses many very large .tif files. So, I am leaning toward it being an .eps/.ai issue??
Issue implies there's something wrong, but I think this is just the way
it's supposed to work.
Line drawings, while usually fairly compact, cannot be lossy compressed.
The marketing department, though, may compress their very large TIFF
files as much as they like (with a corresponding loss of quality). It's
entirely possible to compress bitmaps to a smaller size than the
drawings those bitmaps were made from. You could test this yourself.
Just open a few of your EPS drawings in Photoshop, save as TIFF, place
in ID, and try various downsampling schemes. If you downsample enough,
you'll get the size of the PDF below a PDF that uses the same graphics
as line drawing EPS files. But you may have to downsample them beyond
recognition...

PDF File Size - any way to compress further?

We have are using the Crystal for .NET export method to export a report to a .pdf file, and are having an issue with the pdf file size on a report that contains images. The images are stored in a SQL2005 database as blob or varbinary(max). The report executes a stored procedure that selects data (including images) to produce a quotation. There are input parms to decide which images to print (for example A, B or both A&B). Both types of images can appear at the line level on the quotation. Type A images print in the main report, Type B images are in a subreport. Both the main report & subreport execute a stored procedure to select an image type.
Our issue, when both Type A and B image is selected to print on a 293 line quote. The PDF file size is 44.23MB
When Type A only is selected, the PDF file size is 2.64MB
When Type B only is selected, the PFD file size is 43.95MB.
There are more Type B images that would print at the line level than Type A, but is there any way to compress this down further as it is too large to email.

You mention that you are using Crystal for .NET, but not what version; CR for .NET 2003, 2005, 2008. 2010?
Applying the latest fixes for the correct version of CR would be the first thing to do.
Next, I'd have a close look at image B as it appears to be the one adding the most "bulk". How is this image different from image A?
General tips re. images:
Save the files a BMPs.
When .jpg image is inserted into Crystal Reports it is converted into bitmap format and as the result of the conversion the report may loose some quality, scale and other issues may arise... E.g.; Crystal Reports is not so good a graphics management tool
When an image is saved as a .bmp, then there is no conversion required and thus the quality of the image should be preserved.
Best practice: save the image with high resolution and required size as a .bmp format then insert this image into Crystal Reports.
Resize the image to the smallest possible size and downgrade the DPI to 72. This will ensure your image is as small as possible and Crystal Reports will have to put in the least amount of work to display it.
Have a look ar KB [1241630 - Exporting a Crystal report (XI) to PDF generates a big PDF file|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233343331333633333330%7D.do]. This KB, may apply to your version of CR, or not. In any case, you will have to use the KB as a guide and determine what the appropriate registry entry would be for your version of CR.
One more thing. Many people like to use jpg files as they are smaller than bmp files. However, as far as Crystal Reports is concerned, this is inconsequential. The report file will be the same size if a file is inserted as a jpg or a bmp. This is due to the jpg conversion to bmp Crystal Reports does internally.

PDF file size too large

Hi,
I have a report (6i and 9Ids) which contains an image (stored as a blob in the database (8i)). The size of the image in the database (and as a file) is just 750k. The image is sized to fit on to the A4 report page. If I set the desformat of this report to PDF the resulting PDF output file is 10mb in size. I need to make this report available over the web so this is too large. Has anyone got any ideas as to reducing the output file size?
I have tried the pdfcomp report parameter with no joy.
Cheers
Andy

Hi Andy,
The image you are using might be a JPEG image. In 6i and 9i, while generating the PDF file, Oracle Reports always converts the image to GIF and embed it. This image type conversion increases the file size of the outputimage and hence PDF file size increases. This is fixed in Oracle Reports 10g.
In Oracle Reports 10g, you can select the outputimageformat based on your need, using either:
1. commandline: OUTPUTIMAGEFORMAT
(or)
2. environment variable: REPORTS_OUTPUTIMAGEFORMAT
If your image in the database is a JPEG image, set the outputimageformat to JPEG. Hence, there will not be any image type conversion and the PDF file will be very small.
Please refer to the Publishing Reports manual to know more about the usage of these commandline/environment variable.

Reduce PDF File Size - any ideas?

Hi all,
I have a C++/C# programs that generates PDF's in Adobe Reader using Infragistics. This is a recent change from using VS View as our old method of illustrating - we now use Infragistics. This has resulted in our PDF File sizes almost doubling due to us now using Bookmarks within the PDFs and also having to embed the fonts. There are some pictures used but these are already very small so they are not the issue. I was wondering does anyone have any ideas of how we could possibly reduce the size again or any possible work arounds.
Any help would be great.

Where do these EPS files come from Photoshop or Illustrator?
Illustrator
There may be nothing wrong with EPS files technically, they are considered archaic in a modern workflow. Best to save as a .ai with pdf compatible file - or to save them as PDF x4a with Illustrator Editing Capabilities enabled.
But I don't think there's any need to run out and convert all your files - perhaps keep it in mind going forward.
Photoshop
EPS is really not the best format. If it's pure raster then PSD or TIFF would be preferred format, if it's Raster + Vector Shapes, Vector Masks, Text Layers then PDF is preferred over EPS (with photoshop editing capabilities enabled).
File sizes react differently depending on the content on the choice of compression. Heavy Vector files from Illustrator can cause Huge file sizes in PDFs.
See this article (and more importantly the comments!)

If you can provide a bit more info on your workflow and what settings you are using to save it would be great.

Question about reducing PDF file size on export

I have a large file that is generates a PDF about 75MB when exported with the "[High Quality Print]" preset. However, I can reduce the size down to to under 5MG in Acrobat if I use the Tools>Flattener Preview>[Medium Resolution] setting (image attached). Is there a way to generate this smaller file directly from InDesign? I couldn't figure out how to do this with InDesign's Flattener Preview or Export options, but it is very likely that I missed something.

Eugene Tyson wrote:
When you choose Smallest File size, it is still using the PDF 1.6 setting.
Change this to Acrobat 4 (PDF 1.3) this will automagically flatten the PDF - which means you shouldn't have to do it in Acrobat.
That should get you a nice small file size, I believe.
Flattening transparency in InDesign will not necessarily yield a smaller PDF file size. Transparency flattening will not automatically convert placed vector artwork to raster images unless that vector artwork is actually involved with transparency. And even then, whether you end up with a smaller file depends on a number of factors.
If the reason for the very large file size is indeed very complex vector artwork and you are willing to sacrifice quality, conversion of such vector artwork to raster might yield a significantly smaller exported PDF file. To accomplish that conversion, I would personally suggest converting the most offensive (in terms of file size and complexity) of such files in Illustrator (assuming that they were .AI files) and exporting them as .TIF files (to avoid the potential imaging artifacts of JPEG compression).

PS Elements 8 - "Save As" PDF File Sizes Huge

In Photoshop Elements 8.0, Photoshop PDF file sizes are huge when using the "save as" function, using JPEG compression.
No matter which "Image Quality" is used, the resultant PDF is huge. At "high" quality the file is 20 MB. At "medium" quality, the file is 15 MB. At "low" quality, the file is also 15 MB, much too large. This was not a problem in older versions of Elements. File sizes were typically just more than 3 MB.
If I save the image as JPEG files using "maximum" (10) quality, "medium" (5) quality, and "low" (3) quality, I can insert the image(s) into Word and use the Acrobat Pro PDF printer driver to get PDF file sizes of 1.8 MB, 1.3 MB, and 1.1 MB. These PDF files are perfect. Even the lowest quality is perfectly readable for my purposes. The older versions of Elements worked fine so I didn't need to take the step of saving in JPEG format, importing to Word and then printing.
Does anyone know if Photoshop Elements Version 8 is capable of saving PDF files in the smaller file sizes? Is there a plug-in I can purchase that would give better results?
Photoshop Elements Version 8.0 (20090905.r.605812) with all updates applied.
OS = Windows 7 Enterprise (6.1, Build 7600).
Thank you for any help or adevice.

I'm dealing with the same situation.
With Photoshop Elements I use to scan a picture at 300 dpi, save as PDF file, jpg compression medium low
quality and alway got files under 5 Mb, even lower than that. Colour or black and white pictures.
Now with Photoshop Elements 8.0 did the usual procedure but the pdf are huge, larger than 8 Mb, even more
than 10 Mb !
Am I missing any detail in settings program, perhaps ?
Thanks for any suggestions.

PDF file size in relation to number of pages of the exact same document

PDF file size of a document for one page is 28kb. PDF file size of a the same document for two pages (1st page and 2nd page are exact same document), also 28kb. Shouldn't it be 56kb??

First of all, you can't use Adobe Reader to add, delete or duplicate pages in a PDF file (unless you use a template object), so you're either using Adobe Acrobat, or some other application entirely.
The size of PDF files is not linear, ie if you have 1-page file and it's 1 MB, then duplicating it will results in a 2-page file of 2 MB, or a 10-page file of 10 MB. Many items in a PDF document only need to be saved once (such as font information, image information in some cases, etc.), so the change in size when adding additional pages is sometimes very small. At other times it can be very big, though. You can have a 100-page file that is 1 MB and then add a single page to it, with a new font perhaps, and the size will jump to 5 MB, just because that font is very large...

InDesign Transparency Effect vs. pdf file size

I have an Interactive pdf that was created from InDesign. There is "inner glow" is an effect style created box style. This box style is used a number of times in the 30 page document. The glow is a gradient from black to transparent which looks like an inner shadow for the boxes (sample attached). When I generate the pdf file, size is about 12 Mgb, too large for the target audience.
When I alter the style in InDesign to say something simple like a 10% black solid fill, the pdf file size decreases to about 1 Mgb.
Looked into "flattening transparency" options but this creates pdf that has none of the interactive buttons and links that are required.
Really would like to avoid creating these boxes in photoshop since there are about 40 different sizes of the box.
Any ideas would be greatly appreciated!

For some reason I can't find reply on Forums site, so replying to this
email

Exporting an Interactive pdf using the attached (14.5) jpegs settings

Interactive PDF file size

Hi all,
Is there a way I can reduce an interactive PDF file size. As per my understanding it can be done with ES2 PDF generator in AdminUI, but I am looking to do this in the process(work flow).
Any suggestions?
Many thanks,
Tanmay

Using 72dpi instead of the presets only reduced the file size by a couple hundred kilobytes.
Could it have to do with my buttons on the master pages? I've had real problems with them not working across the various documents that get combined in book form.
