How to repair a damaged PDF
Upload a PDF that won't open, opens with errors, or displays incorrectly in some viewers, and its internal structure is rebuilt from scratch — recovering the file where the underlying content is still intact but its structural wrapper (cross-reference table, trailer) got corrupted.
This commonly happens after an interrupted download, a crashed export, or a file that was only partially written to disk.
Frequently asked questions
What kinds of PDF problems can this fix?
Common structural issues like a broken or missing cross-reference table, a truncated trailer, or an interrupted save — the kind of damage that makes some viewers refuse to open a file, or open it with pages missing or garbled, while others render it fine.
Can this recover a file that won't open in any viewer?
Not always. If a PDF's content itself is too badly damaged to parse — not just its structural wrapper — no automated repair can reconstruct data that no longer exists in the file.
Will repairing change what the PDF looks like?
No — the visible content, layout, and page order are untouched. Only the file's internal structure is rebuilt.
Does this work on password-protected PDFs?
No — remove the password first with Unlock PDF, then repair the result.
