Compress PDF — smaller files, fast
Make big PDFs small enough to email or upload. Pick a compression level and BunnyConvert re-renders the document to cut the size while keeping it readable. Files are processed locally — nothing is sent to a server.

Frequently asked questions
- How much smaller will my PDF get?
- Image-heavy PDFs shrink the most. Text-only PDFs may change little; the original is kept if compression wouldn't help.
- Does compression lower quality?
- You control the trade-off with the quality level. Balanced keeps documents clearly readable.
- Is there a file size limit?
- Standard compression is free on the web with no limits. Files over 20MB and the strongest compression level are Pro features.
