Repair a Corrupt PDF File
When a PDF refuses to open, throws "file is damaged" errors, or displays blank pages, its internal structure is often partially broken rather than completely lost. This tool re-reads the file tolerantly, rebuilds the page tree and cross-reference tables, and saves a fresh, valid document containing everything that could be recovered. The whole rescue operation runs in your browser — a real advantage when the broken file contains private information.

Frequently asked questions
What kinds of damage can be repaired?
Broken cross-reference tables, truncated downloads, corrupted page trees, and minor structural errors are commonly fixable. Severely overwritten files may only be partially recoverable.
Will I get all my pages back?
The tool recovers every page whose content is still intact in the file. Pages stored in irreparably damaged sections may be missing from the output.
Does repair change the quality of recovered pages?
No. Recoverable page content is copied without re-encoding, so text and images come out exactly as they were stored in the damaged file.
