Why I Finally Stopped Paying for BetterZip
Mac users have a weird relationship with file compression. Apple gives us the built-in Archive Utility. It unzips standard files perfectly fine. Then someone emails you a password-protected RAR archive. You double-click it. Nothing happens. That exact moment is how MacItBetter sells BetterZip licenses. BetterZip costs $25. It lets you peek inside archives without extracting them. It handles weird formats like TAR and TGZ. It integrates nicely with Finder. I paid for it years ago. I kept paying for upgrades. But $25 feels steep for a utility that mostly handles file formats from 2004.
People start looking around when the upgrade prompts hit. The Mac software ecosystem has shifted heavily toward subscriptions. BetterZip has stuck to a paid-upfront model. I respect that. Yet the app itself feels stuck in time. The interface looks like something built for macOS High Sierra. We are well past that era. There is also the reality of modern computing. We share links now. We use Dropbox or iCloud. The need to split a 4GB video file into fifty 100MB ZIP chunks is dead. You just send a link. Paying a premium for advanced archive splitting feels unnecessary.
I spent the last three weeks testing free archive managers on an M3 MacBook Pro. I threw everything at them. Corrupted ZIPs. Massive 50GB TAR files. Encrypted 7z archives. I wanted to see if any free tool could actually replace the convenience of BetterZip. The built-in Quick Look plugin is the hardest thing to give up. Being able to hit the spacebar and see what is inside a ZIP file saves hours over a year. Most free tools force you to extract the whole thing just to find one PDF.
I dug through GitHub repositories and Homebrew casks to find better options. Some are open-source projects maintained by one person. Others are free versions of paid apps. A few are command-line tools that run circles around graphical apps. You do not have to pay $25 to open a RAR file in 2024. Here is what I found during my testing.
Detailed Alternative Reviews
Keka
The reliable open-source standard for Mac
brew install --cask kekaI have used Keka for over a decade. The icon used to be a weird pillbug. Now it is a slightly better pillbug. You drop files on the dock icon to compress them. You drop archives to extract them. The preferences menu is dense. You can set it to automatically delete the archive after extraction. I tested version 1.3.8 on an M3 Max chip. It ripped through a 14GB ZIP file in seconds. The App Store version costs a few bucks. You can download the exact same version from their website for free. The developer relies on donations. It works reliably. The biggest annoyance is the default behavior. If you double-click a ZIP file, Keka opens a tiny window asking where to extract it. You have to go into settings and tell it to just extract to the current folder. Once you fix that, it fades into the background.
Key Features:
- AES-256 encryption support
- Excludes Mac resource forks
- Splits large archives
- Automatic archive deletion post-extraction
- Finder context menu integration
- Native Apple Silicon support
- Password manager integration
- Customizable compression levels
Limitations:
- • Default extraction behavior requires tweaking
- • Interface feels slightly utilitarian
- • Cannot preview files inside archives
- • Dock icon is polarizing
Best for: Everyday Mac users who want a set-and-forget extraction tool.
The Unarchiver
The invisible extraction engine
brew install --cask the-unarchiverMacPaw bought this utility in 2017. They have kept it free. It does exactly one thing. It opens archives. You cannot use it to compress files. I tested version 4.3.5 with a folder of ancient StuffIt files from 1998. It opened them instantly. The interface is almost non-existent. You double-click an archive. A progress bar appears. The files appear in a new folder. That is exactly what most people want. It struggles with heavily encrypted 7Z files occasionally. I found it chokes on massive multi-part RAR files if the naming convention is weird. You will not find advanced features here. There is no password manager. There is no Quick Look plugin. It just replaces Apple's Archive Utility.
Key Features:
- Extracts legacy formats like StuffIt
- Fixes garbled non-English filenames
- Single-click extraction
- Background operation
- Supports Amiga disk files
- Handles split RAR volumes
- Automatic character encoding detection
- Zero configuration required
Limitations:
- • Cannot create archives
- • No file preview capabilities
- • Fails on some modern encrypted 7Z files
- • Owned by a large corporate entity now
Best for: People who just want double-clicking a RAR file to work.
PeaZip
Ugly interface with massive power
brew install --cask peazipI want to love PeaZip. It is open source. It supports over 200 file formats. It has a built-in password manager. The problem is the interface. It is built on Free Pascal. It looks completely alien on macOS. The buttons are weird. The file browser feels clunky. I tested version 9.7.0. The performance is incredibly fast. It extracted a 4GB encrypted RAR file faster than Keka. If you can get past the ugly UI, it is highly capable. You can browse inside archives without extracting them. You can test archives for errors. It handles two-factor authentication for archives. It is a power user tool trapped in a Windows XP interface.
Key Features:
- Supports over 200 archive formats
- Built-in password manager
- Archive conversion tools
- Secure file deletion
- Two-factor authentication support
- Archive error testing
- Checksum calculation
- File preview without extraction
Limitations:
- • Interface is completely non-native to Mac
- • Learning curve is steep
- • Menus are cluttered with Windows-centric terms
- • No native Apple Silicon binary available currently
Best for: Power users who care about format support over aesthetics.
MacZip
The best BetterZip replacement
brew install --cask maczipThis used to be called eZip. A Chinese developer maintains it. It is entirely free. The interface is gorgeous. It looks like a native macOS Sonoma app. It includes a Quick Look plugin. You can hit the spacebar on a ZIP file and see what is inside. This is the main reason people buy BetterZip. MacZip gives it to you for free. I tested version 2.0. The extraction speeds are average. It relies on standard background libraries. The translation from Chinese to English in the menus is occasionally awkward. It supports RAR, ZIP, and 7Z perfectly. You can encrypt archives with AES-256. I use this on my personal laptop just for the Quick Look integration.
Key Features:
- Quick Look plugin included
- Native macOS interface
- Batch extraction support
- AES-256 encryption
- Dark mode compatibility
- Drag and drop extraction
- Excludes .DS_Store files automatically
- Archive preview window
Limitations:
- • English translations are slightly off
- • Closed source software
- • Extraction engine is slower than Keka
- • Website is difficult to navigate
Best for: Former BetterZip users who want Quick Look support back.
7-Zip
Pure command-line speed
brew install 7zipIgor Pavlov created 7-Zip decades ago. The official macOS version is strictly command-line. You install it via Homebrew. You open Terminal. You type commands. There is no graphical interface. I tested the native ARM64 build on my MacBook Pro. It is the fastest extraction tool I have ever used. It uses the LZMA algorithm. It compresses files smaller than any other app on this list. You have to memorize flags. Running '7z x archive.zip' extracts files. Running '7z a archive.7z folder' compresses them. This is not for casual users. It is for developers writing backup scripts. The lack of a GUI is a massive hurdle. The performance makes up for it.
Key Features:
- Incredible LZMA compression ratios
- Native ARM64 binaries
- Scriptable via bash/zsh
- Tiny memory footprint
- Supports massive file sizes
- Strong AES-256 encryption
- Self-extracting archive creation
- Multi-threading support
Limitations:
- • No graphical user interface
- • Requires memorizing command flags
- • Cannot preview files easily
- • Intimidating for regular users
Best for: Developers and server admins who live in the terminal.
Commander One
Dual-pane manager with archive powers
brew install --cask commander-oneThis is technically a file manager. It has a dual-pane interface. It reminds me of Norton Commander from the DOS days. The free version includes built-in archive support. You can navigate into a ZIP file just like a regular folder. You can drag a single PDF out of a 10GB archive. You do not have to extract the whole thing. I tested version 3.5. It handles background operations well. You can queue up multiple extractions. The free version restricts some advanced features. It pushes you to buy the Pro pack. The basic archive browsing is completely free. It feels slightly bloated if you only want to unzip files. It is highly effective if you prefer keyboard navigation.
Key Features:
- Dual-pane file management
- Treats archives like standard folders
- Background operation queuing
- Customizable keyboard shortcuts
- Built-in file viewer
- Regex search inside archives
- Root access mode
- Hidden file toggles
Limitations:
- • Heavy upselling to the Pro version
- • Interface is busy
- • Overkill for simple extraction tasks
- • Steep learning curve
Best for: Keyboard junkies who want to manage files and archives together.
Unzip One
App Store darling with annoying ads
Mac App Store downloadTrend Micro makes this app. You will find it near the top of the Mac App Store charts. It is free to download. It has a clean interface. You can preview files inside archives. It handles RAR and 7Z without issues. I tested version 7.0. The performance is decent. The problem is the constant upselling. Trend Micro really wants you to buy their antivirus software. You get pop-ups. You get warning messages about optimizing your Mac. The core extraction engine works fine. The marketing wrapper is highly annoying. I only include it here because it is incredibly popular. You should probably use MacZip instead.
Key Features:
- Archive preview functionality
- Drag and drop interface
- Secure extraction mode
- App Store updates
- Context menu support
- Selective file extraction
- Encryption support
- Clean modern design
Limitations:
- • Aggressive upselling tactics
- • Bundled with unnecessary cleaning tools
- • Privacy policy is dense
- • Slower than open-source alternatives
Best for: Casual users who only install software from the Mac App Store.
B1 Free Archiver
Cross-platform Java tool
brew install --cask b1-free-archiverThis is an older tool. It is written in Java. It supports its own proprietary B1 format. It also handles ZIP and RAR. I tested version 1.7. The interface is dated. The Java backend makes it feel sluggish compared to native M-series apps. It takes a second or two just to launch. It does allow you to browse archives before extracting. It is fully open source. It runs on Windows, Mac, and Linux. You get the exact same experience on every platform. That is a benefit if you switch between operating systems constantly. For Mac-only users, it feels heavy and slow.
Key Features:
- Proprietary B1 format support
- Cross-platform parity
- Archive browsing
- Password protection
- Open source codebase
- Command line options included
- Split archive support
- Batch processing
Limitations:
- • Java dependency makes it slow
- • Interface looks very dated
- • B1 format is rarely used by anyone else
- • Lacks native Apple Silicon optimization
Best for: Users who work across Mac, Windows, and Linux daily.

Migration Tips
Remove BetterZip Quick Look Plugin
BetterZip leaves its Quick Look plugin behind even if you delete the app. Go to /Library/QuickLook/ and delete BetterZipQL.qlgenerator. Restart your Mac. This stops conflicts with apps like MacZip.
Fix Finder Default Apps
macOS gets confused when you install multiple archivers. Right-click a ZIP file. Hold the Option key. Click 'Always Open With'. Select your new app. Repeat this process for RAR and 7Z files.
Handle CPGZ Loops
Sometimes Archive Utility turns a ZIP into a CPGZ file. Extracting the CPGZ gives you a ZIP again. This means the file is corrupted. Use 7-Zip in the terminal to force extraction of whatever data is left.
Automate with Folder Actions
You do not need a paid app to auto-extract downloads. Right-click your Downloads folder. Select 'Folder Actions Setup'. Attach the built-in alert script and modify it to tell The Unarchiver to open new ZIPs.
Bypass Quarantine Warnings
macOS will flag archives downloaded from the web. If you know the file is safe, open Terminal. Run 'xattr -d com.apple.quarantine filename.zip'. This stops the annoying verification prompts.
Test Archive Integrity First
Before deleting original files, test your new archives. Open Terminal and run 'unzip -t yourfile.zip'. This verifies the file structure is sound. Do not trust silent background compression blindly.
