Repair PDF
Rebuild a damaged PDF so it opens again.
About Repair PDF
A download that cut off, a crashed app or a bad USB stick can leave a PDF that refuses to open. The repair tool rebuilds the file structure and recovers whatever pages are intact, often the whole document.
- If only some pages come back, the missing ones were lost in the damage.
- Try re-downloading the original first if that is possible.
- Keep the damaged file until you have checked the repaired one.
How to use it
- 1Drop the damaged PDF.
- 2Wait while the structure is rebuilt and pages are recovered.
- 3Download the repaired PDF.
Questions
- What kind of damage can it fix?
- Truncated files, broken cross-reference tables and bad headers, which are the most common causes of a PDF not opening.
- Can it recover an encrypted file?
- Only if you have the password; enter it when prompted.
- Is the file uploaded?
- No. Everything runs in your browser, so your documents never leave your device.
