What types of PDF damage can PDFredo repair?

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

Can PDFredo repair severely corrupted PDFs?

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.

Will repaired content look the same as the original?

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

My PDF opens but has strange characters - can repair fix that?

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.

Is the original file changed?

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