Frequently asked questions
How do I zip file viewer?+
Drop your file(s) here and the tool shows the contents and sizes — all in your browser.

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.

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