Honest Limits
This tool re-reads a PDF as leniently as possible and rebuilds a fresh copy of its internal structure, which resolves many common causes of files that won't open. It cannot restore page content that is genuinely missing or physically corrupted.
FAQ
It can fix structural issues like broken cross-reference tables and inconsistent trailers, which are common causes of PDFs that won't open in some viewers.
No. If the actual page content is missing or badly corrupted, repairing the file's structure will not bring that content back.
Some files are too damaged, incomplete, or are not valid PDFs at all, and cannot be automatically recovered.
No. Repair runs entirely in your browser. Your PDF is never uploaded to a server, and nothing is stored.
