Repair FAQs

Frequently Asked Questions

1 What causes a PDF file to become corrupt or unopenable?
Corruption normally occurs due to download interruptions, browser network timeouts, system crashes while writing the file, or bad file-generator coding setups.
2 Can this tool recover data from any corrupted PDF?
It can resolve standard errors like broken cross-reference (xref) indices, page catalog pointers, and stream format mistakes. However, if the file content itself is completely empty or overwritten, recovery is not possible.
3 Does repairing a PDF remove some of its content?
The recovery algorithm is designed to preserve as much content as possible. If specific streams (like a corrupt embedded photo) are unreadable, the engine discards those broken fragments to build a functional PDF containing all other text and pages.
4 Is my confidential file safe when running repairs?
Yes, completely. All scanner diagnostics, parsing rules, and rebuilding scripts execute natively in your web browser. Your private file streams never travel across the network.
5 Can I repair a password-protected PDF file?
Yes, provided the primary file header is intact. The diagnostic script will read the password prompt to unlock the encrypted streams locally and then rebuild the document indexes.
