How much can PDF size be reduced?

It depends on content. Image/scan-heavy PDFs usually shrink 60–85%. Text-heavy PDFs shrink less (10–30%).

Does text stay readable?

Yes. The Medium level preserves text and image readability with the best compression ratio for email.

Are files uploaded to a server?

No. Compression runs in your browser — confidential files stay private.

Does it work on mobile?

Yes. Just open it in Chrome/Safari on mobile, upload the PDF, and download the result to your gallery.
