faq
Questions, answered.
01What kind of damage can be repaired?
Structural damage: broken cross-reference tables, malformed objects, bad trailers. The parser reads what is recoverable and rewrites a clean file. Missing or overwritten page data cannot be reconstructed.
02What if the repair fails?
You get a clear error instead of a broken download. In that case the file is likely damaged beyond what any structural repair can recover.
03Is Repair PDF free to use?
Yes, Repair PDF is completely free, with no sign-up and no usage limits. It runs entirely in your browser, so your data never leaves your device.
