A million years ago, I cooked up an InDesign PDF Export Preset to handle exporting PDFs that worked well on the then-brand-new iPad while maintaining relatively small file sizes.
I still use that preset basically every day, having published dozens of books with it. You can download it here.
Adobe has instructions for loading PDF presets.
July 31 2022 edit: I’ve updated this Preset to correct an accessibility issue, and to not generate layered PDFs by default.
A few notes:
- “Embed Page Thumbnails” is disabled because the thumbnails that InDesign creates are lower quality than the ones than Acrobat creates on the fly the first time it loads a PDF. July 31 2022: Full disclosure that this information about thumbnail generation is word-of-mouth from at least 10 year ago and may no longer be correct or relevant.
- You can safely change the PPI and Image Quality in the Compression tab.
- If your document includes spot colors, you probably should go to Output -> Ink Manager and tick “All Spots to Process.” (I almost never use spots, so this advice may be inadequate for your needs.)
- There are no security settings set, because I want my customers to be able to hack the documents they buy, and PDF security is trivially cracked.
