PeaZip是跨平台基于FreePascal的免费绿色便携的解压缩软件。可以运行在Linux系统和Windows系统。支持鼠标右键操作。
这套软件主要的功能是提供一套具备搜索及浏览历史纪录的压缩档浏览接口，来直觉式地对压缩档内容进行浏览，并可以使用详细的筛选规则。此外也能使用扁平式的浏览模式作为另一种浏览压缩档的方式。
PeaZip提供用户通过图形化用户界面的前端程序来自动产生命令提示列的压缩或解压缩动作。它同时也提供了制作、编辑以及撤消压缩设置档来加速压缩或备份的设置。
其他比较值得注意的功能还包含了文件的切割与合并、安全删档、位式文件比对、文件完整性检查、系统效能监控、随机密码／密钥产生器、及集成进资源管理器右键菜单。除此之外，程序的用户界面（包含图片及颜色配置）都可以自行调整。
PeaZip除了提供Windows及Linux（DEB, RPM及TGZ格式）的安装档之外，亦有对此两种平台提供无需安装的可携式版本。在最近也提供了PortableApps的格式 (.paf.exe).
如同7z，Tar，ZIP等这些知名且泛用的压缩格式一般，PeaZip也支持PAQ及LPAQ格式：尽管这并不建议使用于一般状况下（因为太耗存储器且太慢），这些格式因具备对多数数据结构有最佳的压缩比，在压缩科技上具有重大突破，所以还是列入支持。
