Download NanaZip – Modern File Archiver for Windows 11

NanaZip is a free, open-source file archiver for Windows derived from the popular 7-Zip codebase. It modernizes the 7-Zip experience with a native Windows 11 look and feel, deep integration into the Windows context menu, and improved support for modern Windows shell features including the compact context menu available in Windows 11.

NanaZip supports all the same archive formats as 7-Zip — including 7z, ZIP, RAR, TAR, GZIP, XZ, BZIP2, ISO, WIM, and many more — while adding a more polished, fluent-design-aligned interface. It also adds additional features like per-file hash calculation (MD5, SHA-1, SHA-256, SHA-384, SHA-512, BLAKE2, BLAKE3) directly from the right-click menu, making file integrity verification quick and accessible.

As an actively maintained fork of 7-Zip, NanaZip receives security patches and feature updates independently, and its open-source nature ensures transparency. It is an excellent modern replacement for 7-Zip users who want better Windows 11 integration without sacrificing compression performance or format compatibility.
