Open TAR.GZ Files on Windows — No 7-Zip or WSL Required
Windows 11 gained basic TAR support in 2023, but .tar.gz decompression through File Explorer remains unreliable — it often extracts the gzip layer but leaves you with a .tar file you then need to open again. .tar.bz2 and .tar.xz have no native Windows support at all.
FastZip extracts all TAR variants in one step, directly in Chrome or Edge on Windows. No 7-Zip download, no WSL setup, no IT ticket.
Windows 11 vs FastZip for TAR.GZ:
Windows 11's built-in tar command (in PowerShell or Command Prompt) can extract .tar.gz: tar -xzf archive.tar.gz. But this requires Terminal access, correct working directory, and flags you may not remember. File Explorer's drag-and-drop TAR support is limited and sometimes produces a double-extraction step. FastZip handles the full extraction graphically in one step with a file listing view.
Corporate Windows machines without admin rights — Many Windows workstations in enterprise environments are locked down: no ability to install 7-Zip, winget, or Chocolatey. WSL requires a Windows Features enable that needs admin approval. FastZip runs in Edge or Chrome — no install, no admin, no approval process needed.
Developers on Windows receiving Linux source archives — Open-source projects distribute source as .tar.gz or .tar.xz. If you work on Windows but need to inspect Linux project source (check a Makefile, read a README, verify a file structure), FastZip gives you the file listing and allows selective download without extracting everything.

Opening npm Package Archives (.tgz) on Windows
npm distributions are .tgz files. When you run npm pack or download a package tarball directly, you get a .tgz archive. If you're on Windows and need to inspect the package contents — check what files are included, verify the package.json, look at the built dist files — FastZip gives you instant access without any command-line setup.
Drop the .tgz file into FastZip in Edge or Chrome. You'll see the package/ directory with all contents listed. Individual files can be downloaded for inspection.
Extracting TAR.GZ on Windows Without PowerShell
Not everyone is comfortable with the command line. FastZip's graphical interface works like a file manager: you see the archive contents, click to download files, and everything lands in your Downloads folder.
For Windows users who just received a .tar.gz from a Linux colleague and want to open it without learning any commands, FastZip is the simplest option. Open Edge (which is installed on every Windows 10 and 11 machine), navigate to fastzip.io, and you're done.
