How to Unzip RAR Files Without Installing Software (Online Methods)

Unzip RAR in Seconds — Best Tools and Step-by-Step InstructionsRAR (Roshal Archive) files are a common compressed archive format that can bundle multiple files and folders into a single package while offering strong compression and optional encryption. If you’ve ever received a .rar file and weren’t sure how to open it fast and safely, this guide covers the best tools for Windows, macOS, Linux, Android, and iOS, plus clear step-by-step instructions and troubleshooting tips.


Why RAR is different

RAR is a proprietary format developed by Eugene Roshal. Unlike the ubiquitous ZIP format, RAR often offers better compression ratios and more advanced features like multi-volume archives and stronger encryption. Because it’s proprietary, native OS support is limited — you usually need a dedicated extractor.


Best tools by platform (quick overview)

Platform Best Free Tool Best Paid/Advanced Tool Notes
Windows 7-Zip WinRAR 7-Zip handles RAR extraction but not creation for newer RAR versions; WinRAR supports full RAR features.
macOS The Unarchiver Keka The Unarchiver is simple and free; Keka offers better UI and compression options.
Linux p7zip unrar (from RARLab) p7zip extracts many RARs; RARLab’s unrar handles all versions.
Android RAR by RARLab ZArchiver RAR app supports multi-part and password-protected archives.
iOS iZip / Documents by Readdle iZip Pro Files app integration helps on newer iOS versions.

Preparing to unzip safely

  • Scan the file for malware before extraction, especially if from an unknown source. Use your antivirus or upload to an online scanner.
  • Check file origin and verify hashes if provided.
  • If the RAR is password-protected, get the password from the sender — brute-forcing can be time-consuming and legally risky.

Step-by-step instructions

Windows — 7-Zip (free)

  1. Download and install 7-Zip from the official site.
  2. Right-click the .rar file.
  3. Choose 7-Zip → “Extract Here” to extract to the current folder, or “Extract to ” to create a new folder.
  4. If prompted for a password, enter it.
  5. Open the extracted folder.

Windows — WinRAR (paid, trial available)

  1. Download and install WinRAR.
  2. Double-click the .rar file to open it in WinRAR.
  3. Click “Extract To”, choose destination, click OK.
  4. Enter password if required.

macOS — The Unarchiver (free)

  1. Install The Unarchiver from the Mac App Store.
  2. Open The Unarchiver and set file associations for .rar.
  3. Double-click the .rar file in Finder; it will extract to the same folder.
  4. For multi-part RARs, make sure all parts (.r01, .r02, .part1.rar, etc.) are in the same folder.

macOS — Keka (advanced)

  1. Install Keka from the website or Mac App Store.
  2. Drag the .rar file onto the Keka window or Dock icon to extract.
  3. Enter password if prompted.

Linux — p7zip (command-line)

  1. Install p7zip (Debian/Ubuntu: sudo apt install p7zip-full).
  2. Extract:
    
    7z x archive.rar 
  3. For password-protected archives:
    
    7z x -pPASSWORD archive.rar 

Linux — unrar (if needed)

  1. Install unrar (Debian/Ubuntu: sudo apt install unrar).
  2. Extract:
    
    unrar x archive.rar 

Android — RAR by RARLab

  1. Install RAR from Google Play.
  2. Open the app and navigate to the RAR file.
  3. Tap the file and choose “Extract here” or “Extract to” and pick a folder.
  4. Enter password if required.

iOS — Files app / Documents by Readdle

  1. If the .rar is in Files or Mail, tap it; iOS may preview and allow extraction (limited).
  2. For full support, install Documents by Readdle.
  3. Open Documents, locate the .rar, tap it, and choose “Unzip” or use the in-app extractor.
  4. For multi-part archives, ensure all parts are downloaded to the same folder.

Handling multi-part RARs (example: .part1.rar, .part2.rar)

  • Place all parts in the same folder.
  • Open or extract from the first file (usually .part1.rar or .rar). The extractor will read the following parts automatically.

Password-protected RARs

  • Enter the password when prompted.
  • If you’ve lost the password, try contacting the sender. Brute-force tools exist but are slow and may be illegal depending on context.

Troubleshooting common errors

  • “Corrupted archive” — try repairing with WinRAR’s “Repair” feature or re-download all parts.
  • “Missing volume” — ensure all parts are present and correctly named.
  • Extraction stops or files are incomplete — check disk space and antivirus interference.

Tips to unzip in seconds

  • Preinstall your preferred extractor so you can right-click and extract immediately.
  • Use context-menu shortcuts (“Extract Here”) to skip extra dialogs.
  • Keep multi-part archives together and named consistently.
  • For frequent work with archives, use keyboard shortcuts and set default associations.
