Choose the repair tool for your file
This category covers two different damaged-file cases. Choose Corrupt PDF Repair for a damaged PDF, or use ZIP Repair for a damaged ZIP archive. The tools are not interchangeable because they inspect and rebuild different file structures.
What the repair workflow does
The PDF tool diagnoses structural problems such as damaged cross-reference data, malformed object offsets, or truncated pages, then attempts a documented rebuild from the content its parser can still read. The ZIP tool checks archive structures and attempts to recover readable entries from a damaged archive. In both cases, the result is a rebuilt copy rather than an in-place restoration of the original file.
To repair a damaged PDF, open repair a damaged PDF and review the diagnostic findings and recoverable page preview before downloading any rebuilt copy. To recover a damaged archive, open recover a damaged ZIP archive and review the recovery findings and entry statuses before downloading the rebuilt ZIP.
Recovery limits to keep in mind
Repair can only use file data that remains readable. If damage has removed or obscured part of the content, recovery may be incomplete, and neither tool fabricates missing content. Encrypted or password-protected inputs can also affect handling: the tools do not bypass encryption or guess passwords, so some content may remain unavailable for rebuilding.
Keep the original file for comparison. Any repaired result is a newly rebuilt copy, and the availability or completeness of that copy depends on what the damaged input still contains.
