FAQ
How does PDF repair work?
Our tool reads the corrupted PDF structure, identifies damaged parts (XREF table, content streams, fonts), and rebuilds a clean PDF using only the recoverable content. Damaged pages or objects are skipped if they can't be recovered.
What types of PDF corruption can be fixed?
Broken cross-reference tables, corrupted metadata, missing fonts, malformed content streams, partially damaged pages, and invalid object structures. Severely damaged files may have limited recovery.
Will I lose any content?
The tool tries to preserve as much content as possible. If "Remove Corrupt Pages" is unchecked, all pages are kept. Damaged objects that can't be recovered may be replaced with placeholders.
Is my PDF safe?
100% safe! All processing is client-side in your browser. Your PDF never leaves your device. Complete privacy guaranteed.
