RAR files are one of the most common archive formats, but opening them usually requires WinRAR or 7-Zip. BrowserCrunch extracts RAR files (both v4 and v5) directly in your browser using libarchive compiled to WebAssembly. No software installation, no trial periods, no nag screens. Just drop your RAR file and extract.
7-Zip archives offer excellent compression but require dedicated software to open. BrowserCrunch handles 7Z files natively in the browser. Browse the contents, check file sizes, and save what you need. Works on Windows, Mac, Linux, Chromebook — any device with a modern browser.
TAR and TAR.GZ (TGZ) files are common on Linux, in GitHub releases, and in software distribution. Extracting them usually requires command-line tools. BrowserCrunch handles TAR, GZIP, and TAR.GZ archives with a simple drag and drop. No terminal commands needed.
Most online zip tools upload your files to remote servers for processing. That means your private documents, personal photos, and confidential data travel across the internet to someone else's computer. BrowserCrunch is different. Every file is processed locally in your browser using JavaScript and WebAssembly. Nothing is uploaded. Nothing is stored. Nothing is transmitted. Your files stay on your device, period.
WinRAR costs money. 7-Zip requires installation. macOS Archive Utility has limited format support. BrowserCrunch works in any modern browser on any operating system. Perfect for Chromebooks, school computers, library terminals, and locked-down work machines where you cannot install software. Just open the page and start zipping.
No file size limits. No file count restrictions. No daily caps. No watermarks. No account required. No ads. Zip and unzip as many files as you need, whenever you need to. Fast, reliable, and completely free.
