Repair a damaged PDF
Attempts to reconstruct a PDF with light or moderate damage (reference table, trailing bytes or corrupt internal objects) directly in your browser.
or click to select it
Attempts to repair a damaged PDF (inconsistent cross-reference table, truncated trailing bytes or corrupt internal objects) directly in your browser.
Loads the PDF with a tolerant parse that reconstructs the object table when the internal references can't be trusted, and generates a new file with a clean structure. Works well with light or moderate damage; severe corruption (for example, a completely destroyed file ending) can't always be recovered.
Use cases
- Recover a PDF that downloaded incompletely and no longer opens.
- Repair a PDF whose cross-reference table was damaged during a faulty transfer.
- Reconstruct a file with a corrupt internal object before sharing it again.

Frequently asked questions
Does it repair any damaged PDF?
No, it works with light or moderate corruption (reference table, trailing bytes, minor objects). Severe damage, like a completely destroyed file ending, may not be recoverable.
What happens if it can't be repaired?
The tool shows a clear notice that the damage is too severe to reconstruct the file, without downloading anything.
