Frequently Asked Questions
How does the repair work?
The tool reads as much of the PDF's internal structure as possible and re-saves it as a fresh, well-formed file. This fixes broken cross-reference tables and many structural errors.
Can every corrupted PDF be repaired?
No — repair is best-effort. If the file's page data is missing or heavily damaged, some or all content may be unrecoverable. It works best for structural corruption.
Is my broken file uploaded anywhere?
No. The repair runs completely in your browser, so the damaged PDF and the repaired copy never leave your device.
