Frequently asked questions

Which compression mode should I use?

Use Strong for scanned documents and photos, and Lossless for text documents where text must stay selectable.

Is my PDF uploaded to compress it?

Your files are processed inside your browser and are never uploaded to our server, so they stay private.
