A PDF editor that does not lose your work
A PDF editor should never be the reason you lose a document. BergPDF saves to a temporary file, re-opens and validates it, and only then replaces your file.
- Unlimited undo and redo
- Autosave with a recovery dialog after a crash
- Atomic saving: write, verify, then rename; your original stays intact if anything fails
- Incremental saves preserve the original bytes (so earlier signatures stay valid)
- Detects when another program changed the file while you were editing
