No WinRAR, no license, no nag-screen
WinRAR is shareware with an endless trial — and a constant reminder to buy the $30 license. Here the extractor is free, no ads, no purchase nag, no time limit.
Open RAR files in Safari, Chrome, Firefox, or Edge — no software install and no WinRAR purchase nag. Supports RAR v4 and modern RAR v5 (rar5) that current WinRAR writes. Engine: libarchive compiled to WebAssembly.
Drop your RAR file — the engine loads on first use (~600 KB), then stays active for further files.
or click to browse — .rar (v4 + v5)
Saves the WinRAR license and the questionable Mac/Linux third-party tools.
WinRAR is shareware with an endless trial — and a constant reminder to buy the $30 license. Here the extractor is free, no ads, no purchase nag, no time limit.
WinRAR has written rar5 by default since 5.0. Many older browser extractors only handle RAR v4 — our libarchive-based tool covers both. BLAKE2 checksums, AES crypt headers (file content not decryptable), and recovery records parse correctly.
macOS doesn't support RAR natively — double-clicking does nothing. Instead of installing BetterZip ($30) or an App Store extractor with iffy permissions, open the file in Safari or Chrome. Identical on Apple Silicon and Intel.
The proprietary unrar from RARLAB has restrictive licensing — many distributions don't ship it by default. libarchive is BSD-licensed and pre-installed in nearly every distro. Here you use it in the browser, no package manager conflicts.
See every file with paths, sizes, and type icons — pull just the ones you need. From a 1 GB RAR with hundreds of files, that saves huge time and disk.
RAR files often hold legally sensitive material (forensics bundles, legal exhibits, software source drops). Nothing leaves your browser. The WASM engine does come from the CDN but runs fully in the browser sandbox.
Three steps. Engine loads only once.
On first use the tool downloads the libarchive WASM engine (~600 KB). After that it stays active — subsequent RARs open instantly.
Every file with paths, sizes, type icons in a searchable list. Click a single file to save just that one.
Individual file or all at once — bundled as ZIP if you want multiple.
Where browser RAR extraction beats the alternative day to day.
Mods for Skyrim, GTA, Minecraft, The Sims often come as RAR from the modding scene. When picking which ones to load, browse the README and a sample file inline instead of extracting 2 GB.
E-book collections, comic archives (CBR files are RAR!), and manga packs are classically distributed as RAR. Open inline, pull individual volumes — no comic reader needed just to extract.
Some stock sites (Eastern European, Asia-based) deliver asset bundles as RAR instead of ZIP. Instead of installing an extractor, load in the browser and grab the assets you want.
Forensic reports, court exhibits, and IT evidence packets often come as RAR (sometimes with recovery records). Extract in-browser without the data passing through any cloud server — important for client confidentiality and IT chain-of-custody.
On Debian, Ubuntu, and Fedora, unrar-nonfree isn't in the default repo due to licensing. Instead of enabling non-free repos, just use the browser — also works on locked-down library or office machines.
macOS double-click on RAR does nothing. BetterZip costs $30; App Store extractors are murky on tracking. Browser tool is clean, free, and needs no permission beyond drag-and-drop.
With BrowserCrunch you extract RAR files straight in the browser — no WinRAR, no 7-Zip, no BetterZip required. We use libarchive (the same library macOS and FreeBSD use natively) compiled to WebAssembly.
Yes. libarchive supports both older RAR v4 (RAR 1.5–3.x) and modern RAR v5 (rar5), the format WinRAR has written by default since 5.0. Multi-volume RARs (.part1.rar, .part2.rar) need to be merged with a tool before upload.
Yes. macOS doesn't support RAR natively — Apple only ships ZIP. Instead of buying a BetterZip license or installing an unknown App Store extractor, open the file in Safari or Chrome on your Mac. Works identically on Intel and Apple Silicon.
WebAssembly runs in a browser sandbox — the engine can't read or write any file on your device except what you actively drop in. libarchive ships with macOS, FreeBSD, and many Linux distributions, and has been used in production for years.
Not currently. RARs with a password set can't be extracted. You'll need desktop software for those. Unencrypted RARs — the majority — work fine.
On desktop browsers RARs up to ~1 GB extract comfortably. For larger files browser memory gets tight. Multi-volume RARs are supported in principle but must be merged ahead of upload.
libarchive recognizes hard- and symlinks as metadata, but we don't extract them as target-path references — the browser has no filesystem access to create real links. Instead the target content is written directly into the file.
No. The libarchive WASM engine runs entirely in your browser, the RAR file is loaded into local memory, extracted there, and saved locally. No server roundtrip, no logs.
RAR is the second most common archive format after ZIP. Developed in 1993 by Russian engineer Eugene Roshal (hence the name: Roshal ARchive), it compresses many file types better than ZIP. The catch: the format is proprietary, the standard extractor WinRAR is shareware with a nag-screen, and on macOS and Linux there's long been no easy native support. Our online extractor closes that gap — entirely in the browser, free, no install.
Under the hood runs libarchive, a BSD-licensed C library that Apple ships in macOS, FreeBSD ships in the base system, and many Linux distributions ship in their standard repo. libarchive is probably the most carefully tested open-source implementation of the RAR format — Apple and FreeBSD maintainers audit it regularly. We deliver libarchive as a WebAssembly module (~600 KB), lazy-loaded on the first RAR drop. After that extraction runs at native speed because WebAssembly is executed directly by the V8/SpiderMonkey/JavaScriptCore engine.
RAR v4 (standard 1995–2013) uses Huffman+LZSS compression and CRC32 checksums. RAR v5 (rar5, since WinRAR 5.0 in 2013) brings: newer Solid compression with a larger dictionary, BLAKE2 checksums (cryptographically stronger than CRC32), AES-256 (instead of AES-128) for encrypted archives, recovery records up to 2 GB instead of 64 KB, and support for files over 8 EB. Our tool handles both versions automatically.
The RAR format is proprietary and protected by RARLAB (formerly win.rar GmbH) patents. Apple has refused to license RAR and only ships ZIP, TAR, and GZ natively in macOS. Linux distributions ship the proprietary unrar as a "non-free" package that must be enabled explicitly — many server and LTS setups don't have it. libarchive sidesteps the licensing issue because it's a fully clean-room open-source reimplementation.
WinRAR keeps working after the 40-day trial but pops up a license purchase reminder ($29.95 per license, cheaper in bundles) at every start. In businesses that's a compliance issue — either buy hundreds of licenses or formally enforce that no one uses WinRAR. Browser-based extraction is the clean solution: no software, no license, no compliance risk.
Password-protected RARs (filename- and content-encryption) aren't currently extractable — libarchive struggles with RAR's proprietary AES mode. Multi-volume RARs (.part1.rar, .part2.rar, …) must be merged with a tool before upload. Very large archives (over 1 GB) can overrun browser heap — desktop tools win there.
For ZIP files (standard email attachments): our ZIP extractor uses the faster JSZip instead of WebAssembly. For 7-Zip archives: Extract 7Z with the same libarchive engine. TAR, TAR.GZ, and GZIP are covered via the ZIP Tools hub. Create ZIP archives: also in the hub.
