Frequently Asked Questions
Can this tool repair every damaged PDF?
No. It can re-save PDFs that the library can open, but it cannot guarantee recovery of severely damaged files or reconstruct missing content.
Is my PDF uploaded to a server?
This tool processes the selected PDF in your browser. The code does not upload the file to a SmartTools server.
What if my PDF is password-protected?
The current version may not process encrypted PDFs. If the file requires a password, this tool may show an error instead of creating a repaired copy.
Important: This tool attempts to open and re-save a PDF using pdf-lib. It is not a full forensic recovery tool. A successful download does not guarantee that every page or element has been recovered.
