Re^2: Shrink Images and PDFs

[haukex]

For your PDF files, what does gs do or not do which reduce the PDF file size? Is it mainly ebook option?

Yes, I've found the ebook option a convenient way to downsample the resolution of the images embedded in a PDF to 150 DPI. So this script will have a significant effect on PDF files that are large due to them containing high-resolution images (like scans), and less of an effect on PDFs that are already smaller than ~1MB.

Ah, ok. Thanks for the explanation, mainly because I had not thought of embedded images. I was thinking that ebook option might be restructuring the PDF, using common fonts and removing embedded fonts, etc.

One of the settings of the ebook profile is EmbedAllFonts=true, so I might consider disabling that, but other than that I haven't noticed the gs command modifying anything about the PDFs other than the images.
