How it works
How to repair a PDF
- 01
Drop one or more damaged PDFs into the upload area, or click to browse.
- 02
Click Repair PDF.
- 03
Download the repaired PDF, or a ZIP of several files.
Rebuilds the file
Broken cross-reference tables and damaged file structure are rebuilt, so the PDF opens normally again.
Two recovery methods
If the first repair pass can't fix the file, a second, more thorough method re-creates the PDF from the pages it can still read.
Batch friendly
Add several PDFs and repair them all in one go, then download them together as a ZIP.
Questions
Frequently asked
Why won't my PDF open?
PDFs are often damaged by interrupted downloads, failed email attachments or saving errors. Repairing rebuilds the parts of the file that viewers need to open it.
Can every PDF be repaired?
Not always. If part of the file is missing entirely, only the pages and content that are still present can be recovered.
Can I repair a password-protected PDF?
Unlock the PDF first with Unlock PDF, then repair the unlocked copy.
What happens to my file afterward?
It is deleted automatically after processing.
Is Repair PDF free?
Yes. It is free to use, with no sign-up and no watermarks added to your files.
