How to use Compress PDF

Practical guide

What is Compress PDF?

Compress PDF reduces file size using structural stream optimization or page recompression at controlled DPI and JPEG quality.

Extreme and High presets recompress pages as images for stronger savings. Recommended and High quality prefer structural optimization for text PDFs and light recompression for scans. Stronger compression may reduce image quality.

Helpful answers

Frequently asked questions

Quick answers about compress pdf and how this page works.

Will text stay selectable?

Under Recommended/High quality on text PDFs, yes. Extreme/High may rasterize pages for smaller files.

How much smaller will it get?

Results depend on images; already-compressed files may not shrink, and we keep the smaller version.

Is compression free?

Yes, with free-tier daily limits.

Can I undo compression?

Keep the original upload or an earlier download; image recompression is not fully reversible.
