Bundle files into a .zip, or extract an existing one — even password-protected ones — free, no sign-up, nothing leaves your browser.
Yes, completely free with no sign-up and no limit on how many zip files you make.
Higher compression makes a smaller file but takes longer to create. Lower compression is faster but the result is larger. For files that are already compressed (like JPEGs, MP4s, or other zip files), a lower setting often makes little difference to the final size.
With AES-256, there's no way to recover it — nobody, including us, can open the file without the password. Keep it somewhere safe. The standard/legacy option is technically crackable with the right tools, but don't count on being able to do that yourself either — treat any password you set as final either way.
AES-256 if you actually care about the contents staying private — it's genuinely strong. The standard/legacy option exists purely for compatibility, when you know the person opening it only has Windows' built-in extractor and nothing else — it keeps casual snooping out, but a determined person with common tools can break it, regardless of how strong your password is.
Yes — the "Extract a Zip" tab works with regular zips, and password-protected ones using either encryption type this tool offers, regardless of what created them. RAR files are supported too (extraction only — RAR's compression format is proprietary, so only WinRAR itself can create genuine RAR files).
Yes — both are just zip files with a specific internal structure, so they open the same way as any other zip.
RAR archives can be extracted here, but not created — RAR's compression format is proprietary to WinRAR, so no independent tool can legally create genuine RAR files, only read them. Tar.gz (common on Linux and Mac) can be both created and extracted, but it has no password support — that's a limitation of the format itself, not this tool.
No. Everything happens locally in your browser — your files are never sent to a server, and the zip is built entirely on your own device.
