Reply To: Best Settings for Exporting a PDF for the Web

It's a tricky thing… on the one hand, you'll get the smallest results by printing to postscript and using Acrobat Distiller. But you'll lose hyperlinks, bookmarks, etc., so that may not be so good for an interactive experience. I would suggest:

Acrobat 6 compatibility

Turn off Tagged PDF (won't be accessible or as searchable, etc. but perhaps a bit smaller? I need to do some tests on that.)

Set compression to 150 ppi, jpeg (jpeg 2000 might even smaller, but it's not supported by all pdf readers)

Set image quality to Medium (good enough for onscreen usually)

Set output to convert to destination (preserve numbers), choose sRGB as the target, and say “Include Profiles” (the CMYK profile takes up a lot of space, but since you're converting to sRGB, the rgb profile is only a few K).

Make sure that font subsetting is set to 100%, not zero percent (so you do get subsetting).
