Repair Corrupted PDF Files — Recover Damaged Documents Free

A damaged PDF can appear blank, refuse to open, or throw errors in every viewer. FileMagics Repair PDF rebuilds the internal structure of a corrupted file — fixing broken cross-reference tables, recovering truncated streams, and removing malformed objects — to give you back a readable, usable document.

The repair engine uses PyMuPDF's deep-clean pipeline: it garbage-collects unreachable objects, linearises the file, and rewrites the cross-reference table from scratch. No signup required, and your file is never stored after processing.

Cross-Reference RebuildRewrites the xref table from scratch to fix the most common cause of PDF corruption.

Object Garbage CollectionRemoves orphaned, duplicate, and malformed objects that cause rendering errors.

Stream RecoveryDecompresses and recompresses content streams, recovering truncated or broken data.

Safe ProcessingYour original file is never modified — a repaired copy is returned for download.

Pro Tips

Repair works best on partially corrupted files — severely truncated files may not fully recover.
If the PDF opens but has missing images or garbled text, try Repair first before other tools.
After repair, run through your PDF viewer to verify all pages are intact before sharing.
