When Office says “file format or extension is not valid” or “the file is corrupt and cannot be opened”, the contents usually survived — what broke is the container around them. These repair tools scan the raw file bytes, recover every part that is still intact, and write out a clean file your app can open again.

Repair runs locally in your browser tab, so payroll sheets, contracts and thesis drafts stay where they are. Each tool reports exactly what was healed and what was physically missing — no pretending about data that isn’t there.

Every tool here is free and unlimited — Pro exists only for batch processing and oversized files.
