Frequently asked questions

How do I gzip a file?+

Is my data uploaded?+

No. Gzip a File runs entirely on your device, so even sensitive archives never touch a server.

What ZIP/gzip standard is used?+

Standard formats: ZIP with DEFLATE (RFC 1951) and gzip (RFC 1952), so the output opens in every common archive tool.

Is there a size limit?+

No fixed limit, but very large files use more memory since everything is processed in the browser. Splitting huge files first can help.
