- If the repair fails, the tool reports the failure and does not produce a fake output file.
Frequently asked questions
Can this fix any PDF?
No. Common structural issues (broken xref, some stream errors) can be repaired. Truncated or heavily corrupted files usually cannot.
What if repair fails?
The tool reports the error message from the parser and does not produce an output. Try opening the original file in a dedicated PDF repair tool.
