Repair PDF
Repair a PDF in your browser — rebuild a damaged file's structure and linearize it for faster web viewing. No upload, no signup.
Fix a damaged or unreadable PDF by rewriting its internal structure, then linearize it so compatible viewers can begin showing pages before the whole file finishes downloading. Useful when a PDF won't open, shows errors, or loads slowly because of a broken cross-reference table or corrupted objects. Everything runs in your browser, so the file stays private. Free, no account, no watermark.
