What is GZIP good for?

It compresses single files (logs, JSON, text) efficiently; for many files use the ZIP Creator.

No, compression runs locally in your browser.

Can it decompress .gz files?

Yes — switch to Decompress mode and drop a .gz file.

Drop a file to gzip-compress it, or a .gz to decompress it — entirely in your browser.
