Peazip for Windows

Updated: June 4, 2026 · Full review · Alternatives · Archivers

PeaZip for Windows is a free archive manager that handles 188+ file formats, making it one of the most versatile compression tools available for Windows 10 and Windows 11 systems.

What Is PeaZip for Windows?

PeaZip is a lightweight, open source archiver designed for Windows desktop users who need reliable extraction and compression without paying for software. Version 10.6.0 supports everything from standard ZIP and RAR files to obscure formats like 7Z, CAB, and ISO images. The application runs natively on Windows and handles batch operations, meaning you can extract or compress multiple files simultaneously.

The software distinguishes itself through encryption capabilities—it can create password-protected archives using AES-256 encryption standards. File conversion is straightforward: convert a ZIP to 7Z format, or transform RAR files into more portable formats with a few clicks. No external tools required.

Format Support and Compression

The format library sets this free archive manager apart. While 7-Zip remains the compression standard for 7Z efficiency, PeaZip covers roughly triple the number of formats. This matters if you work with legacy corporate archives, ISO disc images, or international compression standards.

Supported formats include ZIP, 7Z, RAR, TAR, GZIP, BZIP2, CAB, WIM, LZH, ACE, UDF, and 188+ others. The breadth means you rarely need multiple tools on your Windows application shelf.

Compression ratios vary by format. The 7Z codec delivers superior compression density compared to ZIP, though extraction speed across formats remains consistent on modern PC software hardware.

Download and Installation

Getting started with the application is straightforward. The official installer is available from the project repository, and installation completes in seconds on any Windows PC. Learn about acquiring PeaZip through official channels if you prefer direct guidance on sourcing the latest build.

A portable version exists for users who want to run it from USB drives without installation—useful for IT professionals managing multiple Windows systems or those working on restricted machines.

System requirements are minimal. This software runs on Windows 7 through Windows 11 without demanding modern hardware. A standard PC configuration from the last decade handles it without performance issues.

Key Features and Workflow

Archive creation uses right-click context menu integration on Windows desktop. Select files, choose "Add to archive," pick your format and compression level, and confirm. The process mirrors Bandizip's simplicity but with more format options.

Password protection appears during archive creation—set an AES-256 encrypted password before finalizing. This protects sensitive data without requiring separate encryption tools.

Batch extraction handles multiple archives in one operation. Point the application at a folder containing dozens of compressed files, and it processes them sequentially or in parallel depending on your settings.

Pro Tip: Use the "Find in archive" feature from the menu bar to search file contents without full extraction. Press Ctrl+F within an archive window to locate files by name across nested folders—saves time when digging through large backup archives.

Comparison Context

ExtractNow specializes in extraction-only workflows, making it lighter if compression isn't needed. Bandizip offers faster extraction speeds on some formats through optimized algorithms. 7-Zip compresses into 7Z format with superior ratios but supports fewer formats overall.

Choose this free archive manager when format versatility matters more than raw speed or specialized compression ratios.

Final Verdict

This open source archiver solves the "I need to open this weird file format" problem without spending money or cluttering your system with single-purpose utilities. It is stable, regularly updated, and asks nothing in return—no ads, no trial limitations, no nags.
