Unable to open a PDF? It may have a corrupted cross-reference table, broken object streams, or structural damage. oMyPDF's Repair PDF tool runs a multi-engine recovery pipeline — qpdf-wasm rebuilds the file structure, Ghostscript re-renders the content, and pdf-lib reconstructs the document from scratch — returning the first successfully validated result. Works for many common types of PDF corruption.

Repair PDF features
Multi-engine recovery
We try qpdf rebuilds, a Ghostscript re-render, then a structural rewrite — strongest available wins.
Verified result
Every recovered file is re-opened and checked before it's returned, so you don't get a still-broken PDF.

Frequently asked questions
Is the oMyPDF Repair PDF tool free?
Yes. Repairing a PDF is 100% free with no watermark and no sign-up required.
What kind of damage can it fix?
It recovers PDFs with broken cross-reference tables, corrupt or missing objects, truncated saves and structural errors that stop a file from opening. It rebuilds the file's internal index and object structure.
How does it work?
It runs progressively stronger recovery strategies — a qpdf cross-reference and object rebuild, a Ghostscript full re-render, and a pdf-lib structural rewrite — and validates each result by re-opening it, returning the first that works.
Can it recover every file?
Not always. If a file is severely truncated, encrypted, or isn't really a PDF, there may be too little intact data to rebuild. In that case you'll get a clear message rather than a broken download.
Will I lose content?
The goal is to recover as much as possible. Most repairs keep all pages; severely damaged regions may be dropped if they can't be reconstructed. The repair report tells you the recovered page count.
Are my files safe?
Your PDF is processed on our server over an encrypted (HTTPS) connection, repaired immediately, and the file is deleted right after.
