Good to know
- The last-resort pass re-renders pages as images, so text in those pages is no longer selectable.
- Badly truncated files may only be recovered partially.
- The full-rewrite pass uses Ghostscript (GNU AGPL v3, about 16 MB, downloaded only if needed).
Repair PDF FAQ
Will my original PDF be changed?
No. Your original file stays unchanged. Download the result as a separate file.
Why won’t my PDF open?
Interrupted downloads, email gateways and faulty software can damage the cross-reference table or cut the file short. Repair rebuilds the structure so viewers can read it again.
Will repair bring back every page?
When only the file’s structure is damaged, yes — every page is rebuilt. When part of the file is missing (for example an interrupted download), the pages that survived are recovered and the result says how many were lost.
