MacPacker is a free and open source archive manager for macOS. It opens 40+ archive, disk image, and compression formats, lets you peek inside without extracting, drills into nested archives, and hands you exactly the files you want via drag & drop. Open source, because essential tools should be free. Inspired by 7-Zip, but built natively for the Mac.

Features

• Peek inside — Browse the full contents of any archive without extracting a single byte.
• Nested archives — Archives inside archives? Drill in seamlessly, with no intermediate extractions.
• Selective extraction — Drag out exactly the files you need. No more 2 GB extractions for one config file.
• Edit & save — Modify and re-save ZIP archives in place. Editing for more formats is on the way.
• Quick Look — Preview archive contents straight from Finder with the spacebar.
• Finder integration — Right-click any archive to extract here or to a folder, without opening the app.
• Encrypted archives — Open password-protected and encrypted archives.
• Built for the keyboard — Navigate archives with the same keys you use in Finder, with breadcrumbs and sortable columns.
• Smart detection — Recognizes formats by their magic number, not just the file extension.
• Speaks your language — Available in 13 languages.

Supported Formats

MacPacker reads and extracts 40+ formats across archives, disk images, and compression containers. ZIP archives can also be edited and re-saved.

See the full format reference and per-format guides on the website.

Installation

Requirements: macOS 14.6 or later. (macOS 13 was supported through v0.14.1.)

Pick whichever you prefer — all builds are sandboxed, signed, and notarized by Apple.

[!NOTE] App Store releases land a few days after the GitHub and direct downloads, because every build goes through Apple's App Store review. For the newest version, use Homebrew or the direct download.

Pull Requests

MacPacker is still in early development and a few breaking changes are ahead, so pull requests may need rework or some wait time before they can be merged. Opening an issue first to discuss larger changes is appreciated.

Building from Source

Prerequisites

• macOS 14.6 or later
• Xcode 16 or later

Steps

1. Clone the repository (it uses submodules for vendored dependencies and test archives):

   git clone --recurse-submodules https://github.com/sarensw/MacPacker.git
   cd MacPacker
   

   Already cloned without submodules? Run git submodule update --init --recursive.

2. Open the project in Xcode:

   open MacPacker.xcodeproj
   

3. Build and run — click Run or press Cmd + R.

4. Use your own signing team (optional). If you have a different Apple Developer account, create a local override:

   cp Config/SigningOverride.xcconfig.template Config/SigningOverride.xcconfig
   

   Then edit Config/SigningOverride.xcconfig and set your Team ID (find it in Xcode under Settings → Accounts). This file is gitignored and never committed.

Roadmap

• Browse and navigate nested archives
• Breadcrumb and Finder-style keyboard navigation
• Extract selected files via drag & drop to any target
• Extract the full archive at once
• Preview files without extraction (via the system previewer)
• Quick Look and Finder extensions for quick access
• Open password-protected and encrypted archives
• Wide format coverage (40+ formats)
• Edit and re-save ZIP archives
• Delete files and folders inside archives (coming next)
• Create archives and edit more formats
