Frequently Asked Questions about PDF Compress
Is PDF compression private and safe for sensitive files?
Yes! By default, our WASM engine compresses files 100% locally in your web browser. No document data or text is uploaded to remote servers.

Low compression preserves maximum resolution and graphic quality with light stream cleanup. Recommended offers a balanced size reduction optimal for email and web sharing. Extreme compression aggressively optimizes streams for maximum file size reduction.

Server-side engines (pikepdf/qpdf and Ghostscript) are under active integration and will be enabled soon for ultra-heavy PDF file batches.
