Repair a damaged PDF

A PDF that won't open usually has a broken internal index, not lost content. This tool re-parses the file with industry-standard recovery (qpdf) and writes a clean, well-formed copy.

Runs instantly and statelessly: your file is processed in memory and never stored.

How it works
  1. 1

    Upload the broken PDF.

  2. 2

    Recovery re-parses and rewrites the file structure.

  3. 3

    Download the repaired PDF immediately.

Fixes broken cross-reference tables, truncated files with intact objects, and malformed metadata.

Truly destroyed content (overwritten bytes) cannot be conjured back — if recovery fails you get an honest error, not a blank file.

Repair recovers structure, not vanished data. Files with genuinely destroyed content may be unrecoverable — you'll get a clear error, never silent data loss.

Repair PDF — questions

Is my broken file stored?

No — repair is stateless: processed in memory, streamed back, forgotten.

What causes corrupt PDFs?

Interrupted downloads, crashed generators, and email systems mangling binaries are the usual suspects.
