Overview

NanaZip is an open-source archiver that wraps the proven 7-Zip compression engine in a Windows 11-native interface, using Fluent Design elements like Mica backgrounds and a modernized context menu rather than 7-Zip's dated look.

Because it shares 7-Zip's core, format support and compression ratios are effectively identical — 7Z, ZIP, and extraction of dozens of other formats. The value NanaZip adds is entirely in presentation and Windows 11 shell integration.

It's distributed through the Microsoft Store as well as GitHub releases, giving it automatic update management for Store users, something 7-Zip itself lacks.

NanaZip suits Windows 11 users who want 7-Zip's proven compression under a modern, native-feeling interface and don't mind a smaller, community-run project instead of the original developer's build.

How to install NanaZip

    Search for NanaZip in the Microsoft Store and click Install, or use the direct Store listing link.

  2. 2. Alternative: GitHub release

    Download the packaged installer from the project's GitHub releases page if you prefer not to use the Store.

  3. 3. Set context menu options

    Open NanaZip and check its settings for which right-click context-menu entries to enable.

How to use it

  1. 1. Compress a folder

    Right-click a folder, choose NanaZip > Add to archive, and select 7z or zip as the format.

  2. 2. Encrypt an archive

    In the Add to archive dialog, set a password and enable file-name encryption for 7z archives.

  3. 3. Extract an archive

    Right-click the archive and choose Extract Here or Extract to folder.

Safety and privacy

  • Install via the Microsoft Store or the project's official GitHub releases page for verified builds.
  • The project is open source, so its handling of the 7-Zip engine and any modifications are publicly reviewable.
Bundled software
No bundled third-party software in the Store package or GitHub releases.
Privacy
NanaZip operates offline like 7-Zip; the Microsoft Store listing follows standard Store app privacy disclosures.

Known risks

  • As a smaller community project, security review is less extensive than the original 7-Zip project, though the core compression code is shared.
  • Archive parsers are a recurring vulnerability class; keep the app updated.

What's new

  • Current release

    NanaZip is actively developed on GitHub with frequent releases. Check the Microsoft Store listing or the GitHub releases page for the current version and change log.

Pros and cons

Pros

  • Free and open source with 7-Zip's proven compression engine
  • Modern, Windows 11-native Fluent Design interface
  • Automatic updates via the Microsoft Store

Cons

  • Smaller community project rather than the original 7-Zip developer's own build
  • Full visual polish is Windows 11-specific; Windows 10 users see fewer benefits over plain 7-Zip
  • Less name recognition than 7-Zip or WinRAR

Verdict

NanaZip is a great pick for Windows 11 users who like 7-Zip's compression but want a modern interface and Store-managed updates. Windows 10 users or anyone wary of third-party forks may prefer the original 7-Zip instead.
