NanaZip

Free, open-source 7-Zip fork for Windows 10 and 11 with a File Explorer menu and Zstandard support.

87/100

#3 of 10 file compression programs
Facts checked 9 Oct 2026

In short

NanaZip suits Windows 10 and 11 users who want the 7-Zip feature set with a File Explorer context menu, ARM64 support and extra codecs such as Zstandard1. It costs nothing and the code is public1,2. The catch: it has no macOS or Linux builds, and its pages document few features directly, so most of the feature set is documented by 7-Zip1,5,6.

Best for: Windows 11 users who want 7-Zip's features with a File Explorer menu.
