How to repair damaged PDF files:

  1. Select corrupted or damaged PDF files (drag & drop or click to browse)
  2. Click Analyze PDF to detect structural issues
  3. Adjust repair settings in the panel on the right (optional)
  4. Click Repair PDF — the tool rebuilds the PDF structure
  5. Download your repaired PDF files
How it works: The tool uses pdf-lib to parse the PDF and rewrite a clean, standards-compliant file. This fixes many common structural problems (xref tables, object streams, broken offsets, missing %%EOF). Extremely corrupted files that cannot be parsed at all may still fail — those usually require specialized desktop recovery tools.

All processing happens in your browser. Files are never uploaded to any server.
