Convert RAR & 7z to ZIP or TAR.GZ Online
Convert RAR, 7z, TAR, TAR.XZ and ISO archives to ZIP, TAR or TAR.GZ in your browser in one step. Folder structure kept, no upload, no install.
๐ Runs entirely in your browser โ nothing is uploadedTurn any archive into a ZIP in one step
A RAR from a forum or a 7z from a colleague is useless when the person you send it to can only open ZIP files,
and a .tar.xz source package is awkward on Windows. This converter unpacks the archive and repacks
every file into the format you choose, in a single step. ZIP is the safe choice for sharing because Windows,
macOS, iOS and Android open it with no extra software. TAR.GZ is what Linux servers, Docker build contexts and
most open-source projects expect, and plain TAR is handy when you want to compress the result with another tool.
Reading is done by libarchive, the same library behind the tar command on macOS and BSD, compiled
to WebAssembly. It understands RAR 4 and RAR 5, 7-Zip, every TAR variant, GZIP, BZIP2, XZ and Zstandard
compression, ISO images and more, and it recognises the format from the file contents rather than the
extension. Writing uses fflate, a fast pure-JavaScript compressor. When converting to ZIP, files that are
already compressed, such as JPEG photos, MP4 videos or nested archives, are stored without recompressing, which
saves time and doesn't make them bigger.
Why RAR and 7z are not output options
RAR compression is proprietary: only WinRAR and its licensed tools are allowed to create RAR files, so no honest web tool can write them. The open formats offered here cover almost every real need. If someone explicitly asks for a 7z file, they will be able to open the ZIP too. Converting in the opposite direction, from ZIP to TAR.GZ for a server, works the same way: just drop the ZIP.
Private and local
The whole conversion happens in your browser tab. The archive is read from your disk, unpacked into memory, repacked and handed straight to your downloads folder; nothing is uploaded or stored. Because everything is held in memory, very large archives (several gigabytes) may fail on devices with little RAM. For those, extract only the files you need with the Extract Archive tool instead.
