About Repair PDF
A PDF can become damaged by an interrupted download, a failed save or a transfer error, and then viewers refuse to open it. Repair tries to rebuild the internal index of the file so the readable parts can be recovered.
How much comes back depends on the damage. If the problems are fixed you get a rebuilt copy; if nothing was wrong, you get a clean copy of the original. Always check the result before relying on it.
Tips
- Keep your original file; repair always creates a new one.
- If the file is encrypted, unlock it first with the Unlock PDF tool.
- Severely truncated files may only be partly recoverable.
