PeaZip: The Open-Source Powerhouse for File Compression and Encryption

In the realm of file archiving and compression, PeaZip stands out as a versatile and powerful tool tailored for users seeking robust security and flexibility across different operating systems. But what exactly makes PeaZip so unique, and why should you consider it over other similar tools? Let’s delve into the features that distinguish PeaZip from its competitors, followed by an exploration of its unique capabilities.

Unique Features of PeaZip

Bridging GUI and CLI

PeaZip is designed to be friendly for both graphical user interface (GUI) users and command line interface (CLI) enthusiasts. It seamlessly integrates the two, allowing users to export tasks defined in the GUI as CLI scripts. This feature is particularly beneficial for those who wish to automate tasks such as compression, archiving, backup, and extraction, or for those looking to refine tasks beyond the capabilities of the GUI.

Support for Two-Factor Authentication

Security is a paramount concern when it comes to handling files, especially compressed ones that might travel through insecure channels. PeaZip addresses this by offering two-factor authentication (using a password plus a keyfile) for all formats that support encryption. This significantly enhances security, protecting against dictionary attacks and password guessing.

Extensive Format Support and File Management

PeaZip provides a GUI for compression formats that are less commonly supported, such as zpaq, brotli, and zstandard. It also offers platform-agnostic support for 7z/p7zip on non-Windows systems. Beyond compression, PeaZip includes multiple file management features like checksum and hash verification, duplicate finding, archive conversion, and more. These tools cater to a variety of use cases, making PeaZip a comprehensive tool for data management.

Portability and Cross-Platform Compatibility

One of the hallmarks of PeaZip is its portability. The software can be run from removable devices or shared over a network or cloud without installation. It offers the same user experience across all desktop environments and operating systems, which is particularly beneficial for users who work with multiple platforms.

Discussion Insights: PeaZip and NT Paths

A recent discussion on Hacker News highlighted an interesting feature of PeaZip: its ability to explore NT paths that are typically inaccessible via Windows Explorer. For instance, paths like "\?\Harddisk0Partition2" can be accessed in PeaZip, which might refer to system partitions like the EFI partition. This capability is crucial for users who need deeper access to the system for maintenance or data recovery purposes.


Q: Is PeaZip free to use? A: Yes, PeaZip is open-source and completely free to use.

Q: Can PeaZip replace other compression tools like WinRAR or 7-Zip? A: Absolutely. PeaZip can handle almost all formats supported by these tools and offers additional features like two-factor authentication and script exportation from GUI to CLI.

Q: How does PeaZip enhance file security? A: Besides supporting robust encryption standards, PeaZip includes two-factor authentication for added security, making it harder for unauthorized users to access sensitive data.

Q: Can PeaZip be used on MacOS? A: Yes, PeaZip is cross-platform and works on Windows, Linux, and MacOS.


PeaZip is not just another file compression tool; it is a comprehensive solution that bridges the gap between ease of use and advanced functionalities. Whether you are a casual user who needs to occasionally compress files or a power user who requires detailed script automation and enhanced security, PeaZip offers a robust set of features that cater to a wide range of needs. Its commitment to security, flexibility, and cross-platform support makes it a standout choice in the world of file compression and encryption software.
