Repair PDF

PDFredo can fix minor structural corruption such as malformed cross-reference tables, truncated streams, and invalid object references.

Severely damaged files — such as those with missing large data sections — may not be fully recoverable. PDFredo focuses on common minor corruption that causes open errors.

For successfully repaired PDFs, the visual content should be identical. If pages were already corrupted before repair, some content may be missing.

Character encoding issues are usually caused by missing font embedding, not structural corruption. Use our OCR tool to create a new text layer from the rendered image.

No. PDFredo creates a new repaired file and leaves your original untouched.
