PeaZip Portable 5 is the easy to use PeaZip file archiver packaged as a portable app, so you can take your file archiver with you and work with your compressed 7z, ZIP, GZIP, BZIP2, TAR, RAR files and more on the go.

PeaZip can extract most of archive formats both from Windows and Unix worlds: currently 134 file extensions are supported ranging from mainstream 7Z, RAR, TAR and ZIP to experimental ones like PAQ/LPAQ family, currently the most powerful compressor available.
For archive creation, PeaZip suppors a wide range of compression and encryption standard, from fastes to most powerful ones, and allows to export job definition as scripts to bridge the gap between GUI and console applications, and let the user pick the best of the two worlds.

Features of PeaZip includes extract, create and convert multiple archives at once, create self-extracting archives, split/join files, strong encryption with two factor authentication, encrypted password manager, secure deletion, find duplicate files, calculate hashes, export job definition as script.
