How to repair a PDF

Use PDF Repair Tools when a document has broken cross-reference tables, bad object offsets, or truncated pages. Corrupt PDF Repair checks the damaged file, previews recoverable pages, and attempts a documented, non-destructive rebuild. You can download the repaired copy with its diagnostic report.

How to fix a corrupt PDF

  1. Open Corrupt PDF Repair.
  2. Select the damaged PDF for inspection.
  3. Check the recoverable-page preview and diagnostic report.
  4. Download the repaired copy and keep the report with it.

What a PDF repair check looks for

Corrupt PDF Repair checks the PDF's structure before it attempts a rebuild. It looks for broken cross-reference tables, bad object offsets, and truncated pages, then records the repair attempt in a diagnostic report. The rebuild is non-destructive, so the original file remains separate from the repaired copy.

-> recoverable pages preview
-> repaired.pdf + diagnostic report

The preview shows which pages the process can recover. Review those pages before using the repaired copy elsewhere.

When a damaged PDF needs repair

  • A PDF opens with missing or truncated pages. Run the repair check to see which pages are recoverable and create a separate repaired copy.
  • A document reports broken internal references or displays objects in the wrong place. The diagnostic report records the structural issue and the rebuild attempt.
  • You need a record of the repair attempt. Keep the original with the repaired copy and its report.

Choose repair or another PDF tool

Use PDF Tools when the file opens and you need compression, conversion, editing, merging, splitting, redaction, or text extraction. Choose Corrupt PDF Repair when the PDF has structural damage and you need a diagnosis, a recoverable-page preview, or a rebuilt copy with a report.
