About this tool
Repair a Damaged PDF File made simple.
The local QPDF engine rewrites the PDF structure and runs a basic check on the new copy. It may help when cross-reference data is damaged, but it cannot restore missing or destroyed page content, and some files cannot be repaired. The input limit is 200 MB to help protect browser memory. Your original is not changed or uploaded. Open and inspect the repaired file before relying on it; a basic structure check is not a guarantee that every page is correct.
