Repair ZIP

Rescue files from damaged or cut short ZIP archives and rebuild a valid ZIP.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Repair ZIP works

A ZIP keeps its table of contents at the very end, so a cut short download cannot open at all. This tool skips that table and reads every file from its own local header, inflates what it can, and writes a fresh ZIP.

Input: ZIP, DOCX, XLSX, EPUB, APK. Output: ZIP.

How to use Repair ZIP

  1. Drop the broken ZIP.
  2. See which files were recovered.
  3. Download single files or the repaired ZIP.

Tips

  • Nothing is uploaded. Your files stay in this browser tab.

Repair ZIP FAQ

Are my files uploaded?
No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.
Is it free? Are there limits or watermarks?
Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.
Does it work offline?
Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
