Frequently Asked Questions

What types of damage can be repaired?

This tool can fix structural issues like broken cross-reference tables, missing trailer sections, corrupted object headers, and incomplete file transfers.

Will repair always work?

No. Success depends on the type and severity of damage. Severely corrupted files where actual content data is damaged cannot be recovered by any tool.

Is my original file modified?

No. The tool creates a new repaired copy. Your original file remains unchanged on your device.

What if repair fails?

If repair fails, the damage may be too severe for browser-based recovery. You may need specialized desktop software or professional data recovery services.

What are the limitations?

Repair PDF fixes structural errors in the PDF format. If parts of the file (like fonts or images) are physically deleted or overwritten, full recovery is impossible. The tool cannot recreate lost data — only repair the PDF structure around remaining content.
