Frequently asked questions
What kind of damage can be fixed?
Broken cross-reference tables, wrong object offsets and missing file endings — common after interrupted downloads or bad email attachments — are usually fixed with text and links intact.
What happens if the file is badly damaged?
The tool switches to deep repair and recovers every page it can still display, as images. Text on those pages is then not selectable — run OCR PDF afterwards if you need it.
Is a repair guaranteed?
No. If the data for a page is missing from the file, it can't be recovered. You'll see a clear message if nothing could be saved.
Is it safe to repair a file with private data?
Yes. The damaged file is read and rebuilt on your device only, so it is never sent away for recovery.
