Is it safe to compress confidential documents here?

Yes. Our Compress PDF tool processes everything locally in your browser. Your files never leave your device.

How much smaller will my PDF get?

This depends on the original file. Scanned documents with large images will see massive reductions, while text-only PDFs may only shrink slightly.

We use smart downscaling. "Recommended" compression maintains visual quality for screens, while "Extreme" may introduce slight artifacting in photos.

Reduce your PDF file size while keeping content and quality intact.
