How to extract a RAR file online (free)

  1. Drop your .rar file onto the box above, or click to choose it.
  2. If the archive is password-protected, type the password when asked — decryption happens on your device.
  3. Download files individually, grab them all, or repack everything into a .zip.

No WinRAR? No problem

RAR is a proprietary format, so Windows, macOS and most file managers can't open it out of the box. Instead of installing WinRAR or 7-Zip just to open one archive, drop it here: this extractor is powered by libarchive compiled to WebAssembly and opens both RAR5 (the default since WinRAR 5.0) and the older RAR4 format.

Password-protected RAR files

Encrypted archives are detected automatically and you'll be prompted for the password. Everything — including the password — stays in your browser. That matters with RAR archives in particular: uploading a private archive and its password to some website's server defeats the point of encrypting it.

Is it really private?

Yes. There is no upload step and no account. Open your browser's network tab and watch: no request carries your file data. The tool works offline once the page has loaded.

What about .cbr comic books?

.cbr files are just RAR archives of images — drop one in and the pages extract like any other archive.

Multi-part archives

Split archives (.part1.rar, .part2.rar, or old-style .r00/.r01) aren't supported yet, since all volumes have to be read together. Single-file archives of any size work — the practical limit is your device's memory.
