A free, private, browser-only tool
You got a .rar and you don't have WinRAR.
That's why this site exists. Drop the file on the page; we open it inside your browser, show you what's inside, and let you save just the bits you actually want. The archive never leaves your computer.
01.Start here
Open a RAR
Drop a .rar. Browse the tree, preview, save selected files. v4 and v5, encrypted included.
Open something else
The same engine also reads ZIP, 7Z, TAR, GZ, BZ2, XZ, CAB, ISO — basically anything libarchive understands.
RAR → ZIP
Repack a RAR as a clean ZIP. Useful when sending it on to someone with no archive tool at all.
Make a ZIP
Bundle some files into a ZIP. Add an AES-256 password if you want it locked up.
02.Why this exists
"WinRAR has been “evaluation” for thirty years. The world deserves a faster door."
For decades, opening a .rar meant downloading WinRAR, clicking through nag screens, then waiting on a server somewhere to upload-and-extract your file before you could see what was inside. None of that is necessary anymore. Modern browsers can run libarchive natively, in WebAssembly, at nearly the same speed as a desktop app. unrarit is just that, with no fluff.
Stays on your device
The bytes get read by JavaScript and WebAssembly in your browser tab. They never travel anywhere.
No install
Open the page. Drop the archive. Done. No WinRAR, no 7-Zip, no signup.
Works offline
Once the page loads, the tool keeps working without a network. Try it — turn off Wi-Fi.
Doesn't size-cap you
No artificial limits. Your phone's RAM is the only ceiling.
03.Common questions
I don't have WinRAR. Do I need to install anything?
Nope. The whole RAR-reading engine runs inside your browser using WebAssembly. Drop the file, see the contents, save what you need. No download, no signup, no purchase prompt.
Are my files actually private?
Yes. The archive doesn't get uploaded anywhere — decompression happens right inside your tab using libarchive compiled to WebAssembly. You can test the claim: open the page, switch to airplane mode, then open an archive. Everything still works because nothing depends on a server round-trip.
Will it open old RAR files (v4) as well as new ones (v5)?
Both. libarchive handles RAR v4 (the legacy format you might see in older releases) and RAR v5 (anything WinRAR has produced since 2013). Encrypted RARs work too — type the password into the password field before clicking Open Archive.
What about split RARs (.part1.rar, .part2.rar)?
Browser-side multi-volume support is limited. The libarchive WASM build wants all volumes in memory contiguously, which browsers don't make easy. The cleanest path is to rejoin the volumes once with a desktop tool (7-Zip will do this), then drop the resulting single archive on this page.
Is there a size limit?
The only limit is your device's available memory. Browsers cap a single allocation at roughly 2 GB on most systems, so genuinely huge archives are better handled with a native tool. For everyday files up to a few hundred MB, this works without issue.
Why free?
The site costs almost nothing to run (no servers do work — it's all in your browser), so a small amount of unobtrusive advertising covers it. There's no premium tier; there's no premium feature locked behind a signup.
Does it work on mobile?
Yes — though decompressing a big archive on a phone is slower than on a laptop because the work is CPU-bound.
