Compress PDF

Two approaches. Lossless rebuilds the file structure and changes nothing you can see. The stronger levels re-render each page as an image at a lower resolution, which shrinks scans dramatically.

Worth knowing: Anything above "Lossless" flattens each page into an image: the text stops being selectable or searchable. For a text document, try Lossless first — for a scan, the stronger levels are where the real savings are.

Frequently asked questions

Will compression reduce quality?

The stronger levels lower image quality to save space. Lossless does not change how the file looks.

What if the file is already small?

It is returned unchanged, and the page says so. We never give back a bigger file.

Does compressing remove selectable text?

The stronger levels do, because pages become images. Choose lossless to keep text selectable.
