What does this tool do?
GZIP is the standard compression for web assets, logs and Unix archives. This tool uses the browser's native CompressionStream, so it's fast and handles large files by streaming them.
Why use it?
- Open .gz logs and data exports.
- Check how well a file compresses for the web.
- No command line needed.
.tar.gz files
Decompressing a .tar.gz gives you a .tar archive. That's a bundle of files; extract it with your operating system or archive software.
