Repair PDF
Rebuilds the internal structure of a broken PDF. Not every file can be saved; the result says honestly what was recovered.
About Repair PDF
Repair PDF tries to rebuild the internal structure of a damaged PDF so that it opens again. It is meant for files that show an error, open blank, or are reported as corrupted.
Not every file can be saved. When a PDF is too badly damaged, the result says plainly what could and could not be recovered, instead of pretending it worked.
When to use Repair PDF
- Recover a PDF that stopped opening after an interrupted download.
- Fix a file that your viewer reports as damaged or unreadable.
- Rescue a document from an incomplete transfer or a failed save.
Tips for the best result
- Try the original file rather than a copy that has been re-saved several times.
- If the file is password protected, unlock it first: repair cannot work on a locked file.
- Keep your original: always check the repaired copy before deleting anything.
