Where the file size actually goes

Most PDF weight is in images. flarePDF re-encodes embedded JPEGs at the quality you choose, which is where nearly all the savings come from.

Text and vector artwork are kept, so selectable words, crisp lines and logos stay as sharp as the original. An optional flattening step can squeeze photo documents further.
