A file archiver that gets out of your way

7-Zip compresses harder than ZIP, opens almost anything you throw at it, and costs nothing — for personal use or in a business, with no registration required.

Other platforms, source, or an older release: see all downloads.

Why it's worth installing

High compression

Usually 30–70% smaller than ZIP, via the native 7z format.

Opens almost anything

Packs and unpacks 7z, XZ, BZIP2, GZIP, TAR, ZIP, and WIM — plus unpacks over 30 more formats (full list below).

Security built in

AES-256 encryption for 7z/ZIP, and self-extracting archives for the recipients who don't have 7-Zip.

Fits how you already work

  • Windows Shell integration
  • Standalone file manager
  • Command-line + FAR Manager plugin

Works everywhere you need it

Windows XP–11, Server 2003–2025 (32-bit, 64-bit, ARM64), in 87 languages.

Actually free

GNU LGPL (mostly), no registration, no payment — commercial use included.

About this redesign

This is a rebuild of 7-zip.org, the real site for the real project — done as a studio exercise, not something the 7-Zip team asked for.

I like 7-Zip because it's exactly what it says it is: a free, genuinely excellent archiver with no dark patterns and no upsell. What its current site gets wrong is presentation, not substance — the download links sit in a small table with no visual priority, the feature list is one long unbroken paragraph, and every release since 2010 is stacked on a single page. None of that is a content problem; it's an information-hierarchy problem. This version keeps every real fact and gives the one thing most visitors came for, the download, an actual visual priority.
