How to reduce size of compiled pdf with many images

I have a 50,000-word Scrivener document with 70 jpg images. When I remove the images and compile to pdf, the file size is 3.3 Mb. With the images, the compile to pdf file size is 43.5 Mb. However, the images are only a total of 11 Mb, with an average of 156 Kb each. I have already reduced the jpg quality to 80%, and the dimensions fit the page. Also, the jpg quality was originally 95%, and the compile to pdf file-size was still 43.5 Mb. So reducing image quality had zero effect on the pdf file size.

Is there anything I can do to reduce the size of the pdf file? Thanks!

Have you tried compiling to RTF and having a third party app such as LibreOffice (which is free, so no cost to try) convert to PDF?

I do not know the purpose of your PDF but if size is the issue you can try using the app “PDF Squeezer” to “squeeze” the PDF down.

It’s a book. With 70 cartoon images. I’ll try the PDF Squeezer and see what happens. Thanks!

Nope, hadn’t tried that.

Since the file has 70 cartoon images, I’m not optimistic about the result of compiling to RTF. However, since I also use OpenOffice right now, LibreOffice seems like a good idea. I have downloaded that and will try your suggestion and see what happens.

Thanks!

PDF Squeezer reduced the file size to 27 Mb. That is on the ‘light’ compression. Stronger compressions made the jpgs ugly. :squinting_face_with_tongue: This will do for now, and might be as good as it’s possible to get. Thanks again!

Thanks again for the suggestion, but neeeuuuuwww. Didn’t work. The PDF result did not keep the cover page (an image). All the cartoon images were the wrong size (too wide). The italicized (emph) text was the wrong size (too big). The headers and footers were the wrong font. It did reduce the pdf file size to roughly 10 Mb, though. So that was successful. :zany_face:

I’m just baffled as to why a document that is 3 Mb without images, expands to 44 Mb with images that are adding only about 11 Mb of file size. :astonished_face:

Try this :
Compile to PDF
Open the PDF in LibreOffice-Draw
Export to PDF
(?)

Right :face_with_diagonal_mouth:

Maybe to get the quality you need with the JPG images you have, the file size has to be big. That being said, too late to test re-scan an image or two to PNG to see effect? Just a thought.
