Repair PDF — Recover Corrupted PDF Files

The repair tool handles the most common PDF corruption scenarios: broken cross-reference (xref) tables, truncated files (partially downloaded PDFs), corrupted object streams, and PDFs rejected by Adobe Acrobat or macOS Preview with 'damaged file' errors. It rebuilds the document structure entirely from whatever readable data remains.

The tool loads your PDF with lenient parsing — skipping strict validation checks that cause standard PDF viewers to reject damaged files. It then copies all recoverable pages into a brand-new PDF document with a clean, freshly generated xref table and object streams. The output is a standard, fully conformant PDF.

If the underlying page data is intact, yes — all text, images, and formatting are preserved. If pages have corrupted data streams (not just the xref table), those specific pages may appear blank in the repaired version. The tool cannot recover data that has been physically overwritten or is not present in the file at all.

Yes — the repair tool uses encryption-ignoring mode, so it can process password-protected PDFs without needing the password. However, the repaired output will also remove the password protection. If you need to re-apply a password, use the PDF Protect tool afterward (which recommends desktop options for true AES-256 encryption).

No tool can guarantee recovery of all damaged PDFs. If the corruption is severe — such as large sections of binary data being zeroed out, or the file being only a few bytes long — the pages themselves may have no recoverable content. In that case, the tool will either report an error or produce a PDF with blank pages. We display an honest error message rather than returning a fake 'repaired' file.
