Frequently Asked Questions

How does PDF compression work here?

Pages are re-rendered as optimized images and rebuilt into a smaller PDF — most effective for scanned and image-heavy documents.

Will text stay selectable?

Compression rasterizes pages, so text becomes part of the image. For selectable text, keep the original.

Is it free and private?

Yes. It's completely free with no signup, and your PDF is processed in your browser — nothing is uploaded.
