Repair PDF fixes PDF files that will not open or show errors. It tries three repair methods, one after another: first a full rebuild that keeps text, links and forms, then an object by object rebuild, and finally it redraws every readable page. You get a short report of what was fixed.
How to repair a PDF
- Click "Choose PDF file" or drag and drop the damaged PDF into the box.
- The repair starts by itself. Wait a few seconds while the file is checked and fixed.
- Read the repair report to see how many pages were recovered.
- Click "Download PDF" to save the repaired file.

Frequently asked questions
What kind of damage can be fixed?
Broken page indexes (cross-reference tables), wrong data lengths, missing file endings, cut-off downloads and references to missing parts. Most PDFs that show "file is damaged" can be fixed.
Will my text stay selectable?
Yes, in most cases. Only if the first two methods fail are pages redrawn as images, and the report tells you when that happens.
Can it open password protected PDFs?
No. A PDF that needs a password to open is not damaged. Use Unlock PDF first if you know the password.
Is my file uploaded?
No. The repair runs inside your browser, so the file never leaves your device.
Is it really free? Do you add a watermark?
Yes, it is completely free with no sign-up, no watermark and no daily limits. The site is supported by a few non-intrusive ads.
