RAR Opener: Easy RAR to ZIP Converter for Windows, Mac & OnlineCompressed archives are a staple of digital file sharing. RAR is a widely used archive format known for high compression ratios and robust features, but it’s not as universally supported as ZIP. Whether you’ve received a RAR file you can’t open, need to convert RAR to ZIP for compatibility, or want a cross-platform workflow, this guide explains everything: how RAR works, why you might convert to ZIP, and step-by-step instructions for Windows, macOS, and online tools — plus tips for security and best practices.
What is a RAR file?
A RAR (Roshal Archive) is a proprietary archive format created by Eugene Roshal. It supports:
- Solid compression (better ratios for many small files),
- Multi-volume archives (split archives for easier transfer),
- Error recovery records and optional password-based encryption.
RAR files typically use the .rar extension. Because it’s proprietary, native OS support is limited; specialized tools are usually required to create or extract RAR archives.
Why convert RAR to ZIP?
Common reasons to convert:
- Compatibility: ZIP is supported natively by Windows and macOS without third-party tools.
- Sharing: Recipients may be unable or unwilling to install extra software.
- Integration: Many web services, backup tools, and mobile apps accept ZIP but not RAR.
- Simplicity: ZIP often suffices if advanced RAR features (like recovery records) aren’t needed.
Note: Converting does not always preserve RAR-specific features such as recovery records or proprietary compression efficiency. Password-protected RARs should be converted only if you have the password.
Preparing to convert or open RAR files
Before converting or extracting:
- Scan the RAR file with antivirus software.
- If password-protected, obtain the password from the sender.
- Check file size and free disk space — extraction can require several times the archive size.
- Keep a backup of the original archive until you confirm all files are intact after conversion.
Windows: Tools and step-by-step instructions
1) 7-Zip (free, open-source)
7-Zip is a popular free tool that extracts RAR files and can create ZIPs.
Steps:
- Download and install 7-Zip from the official website.
- Right-click the .rar file → 7-Zip → Open archive (or Extract Here).
- If extracting, choose a folder and extract.
- To convert to ZIP: after extraction, select the extracted files/folder, right-click → 7-Zip → Add to archive… → set Archive format: ZIP → OK.
Pros: free, reliable, fast. Cons: cannot create RAR archives.
2) WinRAR (paid, trial available)
WinRAR is the official tool for RAR archives; it extracts and also creates RAR files. It also converts easily.
Steps:
- Install WinRAR and open the RAR file.
- Extract or drag files out to a folder.
- Select extracted files → right-click → WinRAR → Add to archive… → Archive format: ZIP → OK.
Pros: native RAR support and advanced options. Cons: not free long-term (trialware).
3) Command-line (7z)
For scripting or automation:
Example command to extract:
7z x archive.rar -ooutput_folder To create ZIP:
7z a -tzip archive.zip output_folder* macOS: Native options and third-party apps
1) The Unarchiver (free)
The Unarchiver is a lightweight macOS app that extracts RARs.
Steps:
- Install The Unarchiver from the App Store.
- Double-click the .rar file or open it with The Unarchiver to extract.
- To convert, compress the extracted files: select them in Finder → right-click → Compress → creates a .zip file.
2) Keka (free/donation)
Keka is a macOS archiver that extracts RAR and can create ZIP.
Steps:
- Install Keka.
- Drag the RAR onto Keka to extract.
- To create ZIP: set format to ZIP in Keka and drag files into the app.
3) Command-line (brew + p7zip)
Install p7zip via Homebrew for CLI use:
Extract:
7z x archive.rar -ooutput_folder Create ZIP:
zip -r archive.zip output_folder Online converters: Pros, cons, and how to use them
Online RAR-to-ZIP converters provide convenience when you don’t want to install software, but carry trade-offs.
Pros:
- No installation required.
- Works on any OS with a browser.
- Fast for small files.
Cons:
- Privacy and security risks if files are sensitive.
- Upload size limits and slower for large archives.
- Dependent on internet connection.
General steps for online tools:
- Choose a reputable converter (look for HTTPS and clear privacy terms).
- Upload the .rar file.
- Wait for conversion, then download the .zip.
- Verify contents and delete uploads from the service if allowed.
Do not use online converters for sensitive or confidential data unless the service explicitly guarantees deletion and strong encryption.
Preserving metadata, permissions, and timestamps
- ZIP and RAR handle metadata differently. Basic file timestamps generally survive extraction and recompression, but file permissions (especially Unix execute bits and ownership) may be lost or changed when converting between formats or moving between OSes.
- For archives that must preserve permissions and symlinks, consider using tar.gz or zip with Unix flags; on Windows, consider maintaining original files in a disk image or using tools that preserve metadata.
Handling password-protected and multi-volume RARs
- Password-protected RARs require the password to extract. Tools like 7-Zip and WinRAR will prompt for it.
- Multi-volume RARs (.part1.rar, .part2.rar or .r00/.r01) must be present in the same folder; open the first volume (.part1.rar or .rar) and the software will read the rest.
- Converting multi-volume archives usually means extracting the full content first and then creating a single ZIP archive.
Troubleshooting common issues
- “Archive is corrupted”: try WinRAR’s Repair feature or test with 7-Zip. If the archive used recovery records, WinRAR can attempt to reconstruct files.
- “Cannot open .rar on macOS”: install The Unarchiver or Keka; macOS Finder does not support RAR natively.
- “Large archive won’t upload to online converter”: use a desktop tool to convert locally or split the archive into smaller parts if needed.
- “Conversion loses file attributes”: use tar-based formats for Unix permissions or preserve an original backup.
Recommended workflows
- Casual user, single file: Use The Unarchiver (macOS) or 7-Zip (Windows) to extract, then compress to ZIP via built-in OS compress or 7-Zip.
- Frequent converter, mixed OS sharing: Use 7-Zip or WinRAR on Windows; Keka or p7zip on macOS. Keep a simple script to batch-convert archives.
- Sensitive files: Avoid online converters. Use local tools and encrypted containers (e.g., password-protected ZIP with AES encryption or an encrypted disk image).
Security best practices
- Scan archives with antivirus before extracting.
- Don’t run executables or scripts from unknown archives.
- Prefer tools with active maintenance (7-Zip, WinRAR, Keka).
- For sensitive data, use local conversion and encrypted archives.
Quick reference: Commands
Windows (7-Zip):
7z x archive.rar -ooutput_folder 7z a -tzip archive.zip output_folder* macOS (p7zip / zip):
7z x archive.rar -ooutput_folder zip -r archive.zip output_folder Converting RAR to ZIP is straightforward with the right tools. Choose local apps (7-Zip, WinRAR, Keka) for privacy and large files, and reserve online converters for small, non-sensitive archives.
