Frequently asked questions
What kinds of damage can be repaired?
Mild structural issues such as missing cross-reference tables, malformed object streams, and truncated trailers are usually fixable. Severely corrupted files where page content itself is destroyed may not be recoverable.
Can it repair an encrypted or password-protected PDF?
Only if you supply the password. Encrypted files whose password is unknown cannot be repaired because the content cannot be read.
What if the repair does not fully work?
The tool recovers as much as possible. If pages are still missing or garbled, the underlying data may be too damaged. Try the Compress tool as an alternative - it re-writes the PDF structure which sometimes resolves minor issues.
