Fix corrupted or damaged PDF files. Upload a broken PDF and we'll attempt to recover it by rebuilding internal structures.
Coming soon
PDF repair requires server-side processing and is not yet available. This feature will be enabled once the backend service is deployed.

What can be repaired?
Broken cross-reference tables
The internal index that maps objects inside a PDF. When this is damaged, readers often show “file is corrupted” errors.
Partial or interrupted downloads
PDFs from failed downloads or email transfers may be truncated. Repair rebuilds the file structure from what’s intact.
Truncated or missing end-of-file
Files cut short during save or copy may lack the trailer section. Repair reconstructs it from available data.
Corrupted object streams
Internal data structures can become garbled by disk errors or bad software. Repair recovers readable objects and rebuilds the rest.
Repair works best on structurally damaged files. Encrypted PDFs with a forgotten password should use the Unlock PDF tool instead.
