Rebuild damaged cross-reference tables, fix corrupted file headers, and salvage readable document streams.
Files are processed entirely in your browser. Nothing is uploaded.
Select the unreadable or corrupted document.
FileMelo scans for missing EOF trailers, header anomalies, and broken object streams.
Export the repaired document with a reconstructed xref index.
All PDF processing is executed locally in your browser memory via WebAssembly and Web Workers. Your files are never uploaded to any remote server.
No. FileMelo repairs structural flaws — header junk, missing trailers, and a cross-reference table that cannot be parsed. If the page streams themselves were overwritten or zeroed, the content is gone and cannot be synthesised. The report says when nothing was recovered instead of presenting an empty file as a repair.
