FAQ
How much smaller will the PDF be?
Typically 20–40% smaller on Low, 50–70% on Medium, and 70–90% on High. The savings depend a lot on the original content.
Will compression hurt quality?
Pages are re-encoded as JPEG. Low compression keeps quality close to the original. High compression yields smaller files with more visible artifacts.
Does compression keep selectable text?
No — pages become rasterized. If you need selectable text, lower compression preserves more legibility.
