RAR to ZIP

About

🗜️ Convert RAR to ZIP — privately, in your browser

Got a .rar file and nothing on your computer opens it? This Chrome extension turns any RAR archive into a standard .zip you can open anywhere, with no extra software to install.

Drop a file in, get the result out. That's the whole flow — one step, no sign-up, no waiting in a queue.


🔒 Your files never leave your device

Unlike most online converters, this extension does everything locally using WebAssembly. Your archive is never uploaded to any server — there isn't even a server. Open the browser's Network tab during a conversion and you'll see zero outgoing requests.

Every conversion runs in a sandboxed worker thread, then the result is handed to your Downloads folder as a ready-to-use zip. Nothing is cached, nothing is stored, nothing is sent anywhere.


✨ What it does

➤ Unpacks a RAR archive (RAR4 and RAR5) entirely in your browser
➤ Repacks the exact same contents into a .zip
➤ Hands you the zip download automatically
➤ Keeps the original folder structure intact

The rar to zip converter handles archives up to 1 GB. For most documents and photos, it takes a few seconds.


🗂️ Who it's for

1. Anyone on Windows, Mac, or Chromebook who received a .rar and can't open it
2. People who don't want to install yet another archiver just to open one file
3. Privacy-minded users who refuse to upload personal documents to a random website
4. Students and office workers who need a quick rar file to zip conversion between classes or meetings


🔄 How to convert RAR to ZIP

1️⃣ Click the extension icon to open the side panel
2️⃣ Drop a .rar in (or click to choose one)
3️⃣ Wait a moment while it extracts and repacks locally
4️⃣ The converted zip lands in your Downloads folder

No account, no settings, no configuration. The process starts automatically the moment you drop the file.


📁 Why convert?

ZIP is the universal archive format. Every operating system opens zip files natively — Windows Explorer, macOS Finder, Chrome OS. The other format needs a special app like WinRAR or 7-Zip.

When someone sends you a .rar, converting it means you can open the contents immediately, share them with anyone, or upload to services that only accept .zip. One click instead of installing desktop software you'll use once and forget.


🔐 Private and focused

📍 No account, no sign-in
📍 No uploads, no tracking, no server
📍 Works offline after the first load
📍 One job, done well

This is not a cloud service that processes your data on someone else's machine. The conversion happens entirely in your browser tab using compiled C libraries running in WebAssembly. Your data stays on your device from start to finish.


⚙️ Technical details

The extension uses libarchive compiled to WebAssembly to read archives. Extracted contents are repacked using store mode (no re-compression), which keeps things fast since most payloads are already compressed media or binaries.

Supported: RAR4, RAR5, single-volume archives up to 1 GB.
Not yet supported: password-protected archives, multi-volume (.part1.rar, .part2.rar…) splits.
