PDF Tools
Repair PDF
Attempt to recover a damaged or corrupted PDF by re-parsing it with lenient settings and re-saving a clean copy — entirely in your browser. The file is never uploaded. No account, no email.
Frequently asked questions
- Does my file get uploaded?
- No. The recovery runs entirely in your browser, on your own device. The damaged file never leaves your computer and never reaches a server.
- What kinds of damage can it fix?
- It fixes the most common PDF damage: bad cross-reference tables, incomplete saves, orphaned objects, and incremental-update bloat. It cannot reconstruct individual content streams (images or fonts) that have been overwritten or truncated.
- What if the PDF is already valid?
- Before repairing anything, the tool reads the file's cross-reference — the index a PDF reader uses to find each page. If that was already intact it tells you no damage was found, and still re-saves a clean, compacted copy that may be slightly smaller than the original. If it was damaged, it tells you that instead, and that the cross-reference was rebuilt.
- What if the PDF is password-protected?
- You need to remove the password first using the Unlock PDF tool, then try repairing it. The repair tool cannot open an encrypted file without the password.
