Repair PDF
Best-effort recovery for damaged PDFs. We re-parse the file and rebuild a clean, openable copy.
🔒 100% on-device — your files never leave your browser.
Repair is best-effort. We first try to rebuild the document structure; if that fails we reconstruct it from rendered pages (text may become non-selectable). Severely damaged files may not be recoverable.
Use Repair PDF as an app
Install it and Repair PDF gets its own icon, opens in its own window without browser chrome, and keeps working with no connection — because it never needed a server in the first place.
Installing copies the tool itself to your device. It adds no accounts, no tracking, and no way for your files to leave your machine.
Frequently Asked Questions
Is repairing my PDF private?
Yes. Recovery happens entirely in your browser; the damaged file is never uploaded to a server.
What kinds of damage can it fix?
It rebuilds broken file structure (such as invalid cross-reference tables) and, for severe damage, reconstructs the document from its rendered pages.
Is recovery guaranteed?
No — repair is best-effort. Lightly corrupted files usually recover fully, while severely damaged files may not be recoverable in the browser.
