Repair PDF

Try to repair a slightly corrupt PDF that refuses to open.

Your file stays on your device — nothing is sent to our servers.

No options — the file will be re-encoded.

How it works

The PDF is parsed in lax mode (invalid or malformed objects are skipped rather than causing a hard failure) and a clean re-saved copy is written out. Many "won't open" errors come from trailing garbage bytes or off-by-one cross-reference tables that this fixes.

Common use cases

  • Recovering a PDF that a browser or email client corrupted during download.
  • Fixing a file exported from a broken PDF generator that most viewers refuse to open.
  • Cleaning up a PDF with trailing junk bytes appended by a misbehaving process, before archiving or sharing.

Privacy

This tool runs entirely in your browser. Your PDF is never uploaded to our servers — the file stays on your device from start to finish.

FAQ

Will this recover any broken PDF?

No — the tool handles the common "soft" errors (malformed objects, off-by-one xref, trailing bytes). A genuinely truncated file or one with corrupted content streams cannot be recovered.

Is the output identical to a healthy version of the file?

Structurally yes for the fixable errors — pdf-lib re-serialises the objects into a clean PDF. Visually the pages match what a lenient viewer would have shown before the fix.
