Compress PDF in Your Browser — No Upload
Drop a PDF, pick a quality level, and download a smaller version — all in your browser. Best on photo-heavy or scanned PDFs. Because nothing is uploaded, this is the only safe way to compress a HIPAA-protected scan, a tax return, or a privileged legal exhibit for email.

When this is useful

Don't trust us — verify it yourself
Every claim on this page is auditable in 30 seconds:
- Open browser DevTools (F12 or Cmd+Opt+I).
- Switch to the Network tab and tick Preserve log.
- Run the tool with your file.
- You'll see requests for the page, library code, and ad pixels — never for your PDF.
Even better: load the page, then turn off Wi-Fi. The tool still works, because there's nowhere for the file to go.
FAQ
How does the compression work?
Each page is re-rendered as a JPEG at the chosen quality and the new pages are packaged into a fresh PDF. That's why this is most effective on scans and photo-heavy PDFs.
Will the text still be searchable?
No — re-rasterizing loses the text layer. If you need a searchable result, run our PDF OCR tool afterward.
My PDF is already small. Should I compress it?
Probably not. Vector-only PDFs (text and shapes) often grow after rasterization. Use Compress mainly for scans and image-heavy files.
