Files truncated mid-download, broken cross-reference tables, PDFs that one reader opens and another refuses. Repair parses whatever structure survived and writes a clean document around the pages it can recover.
This takes a second on the first visit, then it is cached.
Drop in the file that will not open.
Run Repair.
Check the recovered page count before downloading.
No. If the bytes for a page are genuinely missing, nothing can invent them. Repair recovers what is still in the file and tells you how many pages that turned out to be.
No. Repair PDF runs entirely inside your browser using WebAssembly and the Canvas API — the bytes of your document never travel to us. The only thing that reaches our servers is a counter incrementing by one, and whatever you deliberately choose to save to your library.
Not this one. Repair PDF is part of Baker, at $10 a month — along with the other conversion, compression and security tools, and the AI ones. Signing, editing, watermarking, merging, splitting, rotating, organising and cropping are free, three documents a day up to ten pages each, with no account.
