How to Open a RAR File on Any Device

RAR files are everywhere — downloaded from the internet, shared by colleagues, attached to emails. Yet unlike ZIP files, your operating system almost certainly can't open them without a little help. Here's what's actually going on, and what your options look like depending on your setup.

What Is a RAR File, Exactly?

A RAR file (.rar extension) is a compressed archive format created by Eugene Roshal — the name literally stands for Roshal Archive. Like a ZIP file, it bundles multiple files and folders into a single container and compresses them to reduce total size.

Where RAR differs from ZIP:

• Higher compression ratios — RAR typically produces smaller files than ZIP at comparable settings
• Multi-volume archives — large files are often split across several parts (e.g., file.part1.rar, file.part2.rar)
• Built-in error recovery — RAR archives can include recovery records that allow partial reconstruction if the file is damaged
• Password protection and encryption — RAR supports AES-256 encryption, which is strong and widely trusted

RAR is a proprietary format, which is why no major operating system supports it natively out of the box. You need third-party software to both create and extract RAR files.

Why Windows, macOS, and Linux Can't Open RAR Files Natively

Windows has built-in support for ZIP. macOS does too. Linux distributions handle ZIP and various other formats through built-in utilities. But none of them include a RAR extraction engine by default, because RAR's compression algorithm is proprietary to RARLAB.

This is the root cause of the confusion. Double-clicking a RAR file on a fresh Windows or Mac installation will either produce an error or prompt you to find an app — because the OS genuinely doesn't know what to do with it.

How to Open RAR Files on Windows 🗂️

Your main options on Windows:

WinRAR — Made by RARLAB, the creators of the RAR format. It handles RAR files natively and completely. It's technically paid software but operates on an honor-system trial that doesn't expire functionally. Supports multi-volume archives, encrypted files, and repair features.

7-Zip — Free and open-source. 7-Zip can extract RAR files but cannot create them (creating RAR files requires a RAR license). For most users who just need to open downloaded RAR files, 7-Zip handles the job reliably.

PeaZip — Another free, open-source option with a more visual interface. Built on top of 7-Zip's backend for RAR extraction.

Once any of these are installed, you typically right-click the RAR file and select an Extract option from the context menu.

How to Open RAR Files on macOS

macOS users have fewer built-in options, but several tools fill the gap:

The Unarchiver — Available free on the Mac App Store. It integrates directly into Finder, so RAR files open with a double-click just like any native archive. Widely used and well-maintained.

Keka — A paid option (free on the developer's website, paid on the App Store) that handles RAR extraction and supports a wide range of other formats. Offers more control over extraction behavior.

RAR for Mac (from RARLAB) — The official command-line tool for macOS. Useful if you're comfortable with Terminal and want full RAR functionality including creation.

For most Mac users who occasionally need to open a RAR file, The Unarchiver covers the basics without friction.

How to Open RAR Files on Linux

Linux handles archives through command-line tools and GUI file managers depending on your distribution. The key package to know is unrar, available through most package managers:

sudo apt install unrar # Debian/Ubuntu sudo dnf install unrar # Fedora 

Once installed, extracting is straightforward:

unrar x filename.rar 

Many desktop environments (GNOME, KDE) also integrate with archive managers that support RAR once the unrar package is present. If your file manager shows a RAR file as unopenable, installing unrar and restarting the archive manager often resolves it immediately.

Opening RAR Files on Android and iPhone 📱

Mobile devices can open RAR files with the right app:

• Android: RAR by RARLAB (the official app) is available on the Google Play Store and handles extraction, multi-volume archives, and encrypted files
• iOS/iPhone: Apps like iZip or RAR (also by RARLAB, available on the App Store) provide RAR extraction

Keep in mind that on mobile, you'll also need to consider where the extracted files land — some apps extract to their own internal storage, while others let you choose a destination in your Files app.

Handling Password-Protected and Multi-Volume RAR Files

Password-protected RAR files require the password at extraction time. Every tool listed above will prompt you for it. There's no way around a strong RAR password — AES-256 encryption means brute-forcing is not practical.

Multi-volume RAR files (split archives) need all parts present in the same folder before extraction. You start extraction from the first part (part1.rar or just the .rar file if using the older naming convention) and the tool reads the remaining parts automatically.

What Determines Which Approach Works for You

The right method depends on several overlapping factors:

• Operating system and version — tool availability and integration varies significantly across Windows, macOS, and Linux distributions
• How often you deal with RAR files — occasional use favors lightweight free tools; regular use or professional workflows may warrant full-featured software
• Whether you need to create RAR files, not just extract them — only licensed WinRAR and RARLAB's official tools handle creation
• File complexity — encrypted archives, damaged files with recovery records, and multi-volume sets behave differently across tools
• Technical comfort level — command-line tools offer more control but assume familiarity with a terminal

The mechanics of opening a RAR file are straightforward once the right tool is in place. Which tool is right for your particular system, workflow, and file types is where individual setups start to diverge.
