How this tool protects privacy
This page is designed to run inside your browser. The selected file is not uploaded by the static site. For sensitive archives, avoid tools that require a server upload before they explain how files are handled.
Limitations
Very large archives may be slow. Browser support differs for advanced compression methods. ZIP files using unsupported methods may still be inspected even when every entry cannot be extracted.
