Frequently asked questions
- Can all corrupted PDFs be repaired?
- Not always. SnapOtter can fix structural issues like broken cross-reference tables, but severely damaged files with overwritten data may be unrecoverable. Processing runs entirely on your local server.
- Will repaired PDFs look the same as the originals?
- In most cases, yes. The repair process rebuilds internal structures without altering content. However, heavily corrupted sections may result in missing elements. Files stay on your network.
- Is the original file modified during repair?
- No. SnapOtter creates a new repaired copy and leaves the original untouched. All processing happens on your self-hosted instance so damaged confidential files remain private.
