How much can a PDF be compressed?

Image-heavy PDFs can shrink 40-80%. Text-only PDFs compress less. The tool shows before and after file sizes.

Does compression reduce quality?

Slight image quality reduction may occur. For text documents quality is not affected.

Yes. All compression runs in your browser using PDF-lib. Files are never uploaded to a server.

Password-protected PDFs must be unlocked first using the Unlock PDF tool, then compressed.
