Frequently asked questions

Is the ZIP File Converter free to use? ▼

Yes — completely free with no file-size limits, no daily usage caps and no premium tier. All 247 tools on BunchTool are free forever, with no upsells or paywalls.

Is my data safe and private? ▼

Absolutely. Your data is processed entirely inside your browser using client-side JavaScript. Nothing ever leaves your device or is uploaded to any server.

Does the ZIP File Converter work offline? ▼

Yes. Once this page has loaded in your browser, the tool continues to work without an internet connection. Your browser handles all the processing locally on your device.

Can I convert multi-file ZIPs to GZIP? ▼

GZIP is designed to compress only a single file rather than a directory structure. To convert multi-file ZIPs, choose the TAR option, which bundles multiple files together into a standard TAR container file.

Yes! Once loaded, the converter runs client-side inside your browser sandbox with no external server requests.
