How to Open RAR Files on Windows, Mac, Android, and iPhone
RAR archives are everywhere — game mods, software downloads, photo backups, email attachments — but no operating system opens them natively. You need a third-party tool. The good news: every major platform has a free, reliable option that takes under a minute to install and works for years afterward.
This guide covers the right RAR opener for Windows, Mac, Android, and iPhone, with the specific steps to extract a RAR file and the small details that trip people up — multi-part archives, password-protected RARs, and the security difference between just opening an archive and running what is inside.
Key Takeaways
- Windows: 7-Zip (free, open-source, no nag screen)
- Mac: The Unarchiver (free, App Store, double-click workflow)
- Android: RAR by RARLAB (free, made by the official RAR developer)
- iPhone: Documents by Readdle (free, handles RAR plus 20+ other formats)
- Avoid: Browser-based RAR extractors for files containing personal data or executables
Why You Need a Third-Party Tool
Windows, macOS, Android, and iOS all support ZIP files natively but none of them open RAR archives out of the box. RAR is a proprietary format developed by Eugene Roshal (the source of the name — Roshal ARchive). The compression algorithm is licensed, which is why every operating system ships ZIP support but not RAR.
This means downloading a free third-party tool is the only practical way to extract a RAR file on any platform. The good news is that the best options are open-source, lightweight, and require no ongoing maintenance once installed.
When the Choice of Tool Actually Matters
For a casual one-off extraction, almost any RAR tool works fine. The choice starts to matter in three situations:
- Multi-part archives (file.part1.rar, file.part2.rar, file.part3.rar) need a tool that handles sequenced extraction reliably. Older or stripped-down tools sometimes fail mid-stream.
- Password-protected RARs with AES-256 encryption need a tool that supports modern RAR5 format. Some older free tools only handle RAR4 encryption.
- Large archives (over 4 GB or many thousands of files) benefit from a tool that uses multi-threaded extraction. 7-Zip and WinRAR both do; lightweight extractors often do not.
The Best Options Compared
1. 7-Zip on Windows — the free default
7-Zip is the default answer for Windows users. It extracts every RAR variant including multi-part and password-protected archives, integrates a "7-Zip" submenu into the right-click context menu, and runs entirely offline. It has been actively maintained since 1999 and remains under 2 MB installed.
The only limitation worth noting: 7-Zip cannot create RAR archives, only extract them. If you need to make a RAR file, you need WinRAR. For opening, 7-Zip is the cleaner choice.
Pros
- Truly free, no nag screen ever
- Handles RAR5 with AES-256 encryption
- Right-click context menu integration
- Tiny footprint (about 2 MB)
- Open-source — auditable security
Cons
- Cannot create RAR archives (extract only)
- Interface looks dated
- No native macOS or Linux build (community ports exist)
2. The Unarchiver on Mac — double-click and done
The Unarchiver is the standard free RAR opener for Mac users. Install it from the App Store, set it as the default app for .rar files in Finder (right-click any RAR → Get Info → Open with → The Unarchiver → Change All), and from that point on, double-clicking any RAR file extracts it automatically.
Beyond RAR, The Unarchiver handles 7z, tar, gzip, bzip2, StuffIt, and dozens of niche formats — useful if you also work with archives from older Mac software or Linux systems.
Pros
- Sandboxed App Store install (safer than third-party downloads)
- One-click double-click workflow once set as default
- Handles 30+ archive formats beyond RAR
- Free with no in-app purchases
Cons
- Extract only — cannot create archives
- No active development since 2017 (still works reliably)
- No batch extraction UI for multiple files
3. PeaZip — cross-platform open-source
PeaZip is the right pick when you need one tool across Windows and Linux, or when you want more features than 7-Zip offers without paying for WinRAR. It supports 200+ archive formats, includes a file shredder (secure delete), and offers a more modern interface than either 7-Zip or WinRAR.
For most Windows users, 7-Zip is still simpler. PeaZip becomes the better choice if you regularly handle exotic archive formats, want a built-in file manager view, or work across Windows and Linux machines.
Pros
- Supports 200+ archive formats
- Cross-platform (Windows + Linux)
- Built-in file shredder for secure deletion
- Modern interface compared to 7-Zip
Cons
- Larger install footprint than 7-Zip (~15 MB)
- Interface can feel busy for casual users
- No native macOS build
4. WinRAR — the official RAR tool
WinRAR is made by RARLAB — the original developers of the RAR format. It is the only mainstream tool that creates RAR archives (including the newer RAR5 format with stronger encryption and recovery records). The free trial technically expires after 40 days, but the software keeps working with a nag screen after that, which is why many users treat it as effectively free.
For most users who only need to open RAR files, WinRAR is overkill. Its real value is creating archives, especially when you need RAR5 features like recovery records (which let damaged archives still extract) or multi-part archive creation.
Pros
- Made by the official RAR developers — perfect format support
- Creates RAR archives (not just opens them)
- Recovery records for damaged file recovery
- Strong AES-256 encryption in RAR5 format
Cons
- Paid software (nag screen after 40-day trial)
- Commercial use requires a license
- Overkill if you only need to extract RARs

| Documents by Readdle | iOS | Free | iPhone and iPad RAR handling |
Opening RAR Files on Android and iPhone
Mobile RAR extraction follows a slightly different workflow because of how iOS and Android handle file types.
On Android
RAR by RARLAB (free, ad-supported) is made by the same team that built the format. Install it from the Play Store, tap any .rar file in your file manager or downloads folder, and choose RAR from the open-with menu. The app extracts directly to the same folder by default. ZArchiver is a popular alternative if you prefer a cleaner interface — also free, with optional in-app upgrades to remove ads.
On iPhone and iPad
Documents by Readdle (free, App Store) is the most reliable iOS option. When a RAR arrives in email, Messages, or a chat app, tap the file, choose Share, then "Copy to Documents." The app extracts the archive automatically and stores the result in its file browser. Apple's own Files app does not handle RAR natively — Readdle's tool fills that gap.
How to Open a Multi-Part RAR Archive
Files split across multiple parts (file.part1.rar, file.part2.rar, file.part3.rar) need slightly different handling:
- Put every part in the same folder. If parts are scattered across downloads, move them together first.
- Confirm every part is present. Multi-part archives fail if any single piece is missing. The numbering goes part1, part2, part3 in sequence — gaps stop the extraction.
- Extract only the first file. Right-click part1.rar (or whichever has the "1" suffix, or the one with no number suffix in older RAR versions) and choose Extract. The tool reads the remaining parts automatically.
- Wait for completion. Multi-part extractions can take several minutes on large archives. Do not move or rename the part files mid-extraction.
Common Mistakes to Avoid
Downloading from an unofficial source: Search results for "WinRAR download" surface paid mirror sites and bundled installers. Always go directly to rarlab.com for WinRAR or 7-zip.org for 7-Zip.
Extracting executables without scanning: If an unfamiliar RAR contains .exe or .msi files, scan them with Windows Defender or your antivirus before running. The archive itself is safe; the contents may not be.
Trying to extract only one part of a multi-part archive: You cannot extract part2.rar by itself. All parts must be present and you must start the extraction from part1.
Forgetting the password: RAR's AES-256 encryption is genuinely strong. If you set a password and forget it, the archive is effectively unrecoverable. Save passwords in a password manager.
Uploading sensitive RARs to browser extractors: Sites that extract RARs in the browser are convenient but upload your file to their servers. For confidential content, use a desktop tool instead.
Frequently Asked Questions
What is the best free way to open RAR files on Windows?
7-Zip. It extracts every RAR variant, integrates with the right-click menu, and never shows ads or nag screens. Download it from 7-zip.org.
Can I open RAR files on Mac without paying?
Yes. The Unarchiver is free on the Mac App Store and handles RAR plus 30 other formats. Set it as the default for .rar files in Finder and double-clicking will extract automatically.
How do I open multi-part RAR files?
Keep all parts in the same folder and extract only the first file (part1.rar). Your extractor reads the remaining parts in sequence. Missing or corrupted parts cause the extraction to fail.
Is opening a RAR file safe?
Extracting a RAR is harmless — no code runs during extraction. The risk is in what is inside. Scan unfamiliar executables with antivirus before running them.
Can I open RAR files on my iPhone?
Yes. Install Documents by Readdle (free) from the App Store. Tap any RAR file you receive, share it to Documents, and it extracts automatically.
