Fix damaged or corrupted PDF files and recover your data.
Repairing a PDF attempts to fix structural errors and corruption in damaged PDF files. A corrupt PDF may fail to open, show blank pages, or display garbled content — the repair tool tries to reconstruct the file structure and recover as much content as possible.
Users whose PDFs were interrupted during download or email transfer can attempt repair to recover the file. Database exports that produce malformed PDFs can be repaired before use. Legacy PDF files with deprecated encoding sometimes need repair to open in modern viewers.
Our repair tool attempts to parse and reconstruct the cross-reference table, object streams, and page tree of the PDF. It uses pdf-lib's repair mode to salvage damaged files. Success depends on the nature of the corruption — partial recovery is common.
Your files never leave your browser. No account required, no server uploads — just fast, local processing. This is what it means to repair PDF without uploading.

Upload the damaged PDF to the Repair tool and download the repaired file. Success depends on the type and extent of corruption.
Most PDFs with minor corruption can be recovered. Severely truncated or encrypted files may not be repairable.
The tool preserves as much content in the document as is technically possible.
