When it comes to compressing and decompressing files, WinZip and WinRAR have long established themselves as two of the most widely recognized tools. However, both are proprietary software, often requiring paid licenses after trial periods. Thankfully, there are a variety of open-source alternatives that offer comparable—if not superior—features without the associated cost. Whether you’re a casual user or a professional looking to handle archives daily, these tools provide efficient and reliable solutions backed by active developer communities.
TL;DR: Too Long, Didn’t Read
If you’re tired of paying for WinZip or seeing constant reminders that your WinRAR trial has expired, there are excellent free alternatives available. Open-source compression tools like 7-Zip, PeaZip, and B1 Free Archiver offer robust feature sets without pop-ups or trial limits. These tools support numerous archive formats, are maintained by active communities, and are often faster and more resource-efficient than their proprietary counterparts. This article covers the six best free and open-source alternatives to help you choose the right solution for your needs.
1. 7-Zip
Arguably the most well-known open-source alternative to WinRAR and WinZip, 7-Zip has earned its reputation by offering high compression ratios, broad format support, and minimal resource usage. It works on Windows and has unofficial ports for Linux and macOS.
- License: Open-source (GNU LGPL)
- Supported Formats: 7z, ZIP, RAR, TAR, GZ, ISO, and more
- Notable Features: Strong AES-256 encryption, self-extracting archives, and integration with Windows Shell
7-Zip’s native format—7z—often provides better compression than ZIP or RAR formats. It also includes a powerful command-line version for automation and scripting tasks.
2. PeaZip
PeaZip is a user-friendly, open-source archiver that supports a vast range of file formats. It is especially great for those who prefer a graphical user interface loaded with customization options.
- License: Open-source (LGPLv3)

PeaZip’s interface is designed with productivity in mind, featuring tabbed browsing, drag-and-drop support, and even scripting capabilities. It is available for Windows and Linux.
3. B1 Free Archiver
B1 Free Archiver is a lesser-known tool that combines simplicity and performance into a single, accessible application. Available on major operating systems and even via a web interface, B1 makes file compression incredibly straightforward.
- License: Freeware (open API but partially closed-source)
- Supported Formats: B1, ZIP, RAR, 7Z, TAR, GZ
- Notable Features: Multi-platform support including a browser-based version, encrypted archive creation
Though not completely open-source, its API is available under an open license, which earns it partial inclusion in this list. B1’s clean UI and cloud-based version make it a great choice for light and mobile users.
4. NanaZip
Designed as a modern alternative built atop the 7-Zip infrastructure, NanaZip brings 7-Zip’s core functionality into the Windows 11 ecosystem. It’s available through the Microsoft Store and supports context menu integration with the latest shell extensions.

- Notable Features: Native Windows 11 support, dark mode UI, Microsoft Store distribution
NanaZip appeals especially to users looking for seamless integration with newer Windows updates. If you are upgrading your OS, NanaZip provides a more contemporary UI without departing from the core strength of 7-Zip.
5. Keka
Exclusively designed for macOS, Keka is a powerful, lightweight archive manager that adds excellent functionality to Apple’s desktop platform—often lacking in native compression features beyond ZIP.
- License: Open-source (GPLv3)
- Supported Formats: 7Z, ZIP, TAR, GZIP, BZIP2, XZ, LZMA, ISO
- Notable Features: Native macOS integration, drag-and-drop support, password protection
Though it’s available for free via the developer’s website, Apple users can also support Keka by purchasing it from the Mac App Store. It’s a practical, aesthetically pleasing solution for macOS users.
6. Xarchiver
Xarchiver is a front-end GUI archiver designed for Unix-based systems, making it a top choice for Linux users who use lightweight desktop environments like Xfce or LXDE.
- License: Open-source (GPL)
- Supported Formats: ZIP, TAR, RAR, 7Z, and others via backend utilities
- Notable Features: Minimalist and fast UI, integrates well with lightweight Linux distros
Xarchiver leans heavily on external command-line programs like rar and p7zip to function, but its straightforward interface makes it convenient for users who want a GUI experience without resource bloat.
