Frequently asked questions
How much smaller will my PDF get?
Scans and photo-heavy files usually shrink the most. Choose light, normal or strong compression and you see the new size before you download.
Is there a catch?
In the compressed file each page becomes an image, so the text can no longer be selected or searched.
