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.

Frequently asked questions
What kinds of corruption can be fixed?
Structural issues — missing xref tables, broken object streams, truncated files — are usually recoverable. Encrypted or fully overwritten bytes are not.
Does repair happen on your servers?
No. The repair runs locally via pdf-lib.
Why does my file still not open after repair?
Some corruption is too severe to recover. In those cases the original source (email, backup, or re-export) is your best option.
