How much can I compress a PDF?

Compression ratios vary by content. Image-heavy PDFs typically compress by 50–80%, while text-only PDFs see smaller reductions.

Will compression affect text quality?

Text is losslessly compressed — only images are resampled, so text remains sharp and readable.

You need to unlock password-protected PDFs before compressing them. Use our Unlock PDF tool first.
