Repair PDF

A PDF that will not open is often structurally damaged rather than genuinely lost: a broken cross-reference table, corrupted object offsets or a truncated download. This tool rebuilds the document structure around whatever content can still be read. It is free, needs no account, and adds no watermark to your result.
