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.
A few notes:
- This preset turns all the Layers in your InDesign document into Acrobat layers; so users can hide backgrounds, art boxes, etc. (depending on how you use Layers in InDesign, of course.) You can untick this if you don’t want layered documents.
- “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.
- 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.
