Repair a corrupted PDF
Attempt to rescue a broken file, without uploading it.
A PDF that will not open is usually corrupted somewhere in its structure. This tool tries to rebuild it into a valid file, all in your browser, so a document you cannot afford to lose is never uploaded.

Why repair on your device
A file you are trying to rescue is one you care about. Repairing it in the browser means it is never uploaded to a recovery service.
Frequently asked questions
Can every PDF be recovered?+
Not always. If the structure is rebuildable, it will work; badly damaged files may be beyond repair.
Is my file uploaded?+
No. The repair runs in your browser and the file never leaves your device.
Will I lose content?+
The tool preserves as much as it can while making the file valid again; check the result.
Is it free?+
Yes, with no sign-up.
