Frequently asked questions
Will compression make my PDF blurry?
Shrink images mode re-renders pages at a chosen resolution, which trades some sharpness for a much smaller file — pick a lighter strength if quality matters more than size. Clean up only never touches image quality.
Does compression keep the text selectable?
Only Clean up only keeps text selectable. Shrink images turns each page into a single image, which is what delivers the bigger size reduction.
Is Compress PDF free?
Yes, and there is no sign-up, watermark or daily limit — everything runs in your browser rather than on a metered server.
