Frequently asked questions
How do I gzip a file?+
Drop your file(s) here and the tool creates a .gz — all in your browser.
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.
