Extract GZ files.
Gunzip .gz files in your browser — nothing gets uploaded.
Drop GZ files here
or browse your files
Paste with ⌘V · or drop files anywhere on the page
Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
Log rotations, database dumps and API exports land as .gz — one compressed file, no archive inside. Drop them here and the original comes back: access.log.gz turns into access.log, decompressed entirely on your device. A .tar.gz unwraps all the way to its files automatically.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- Compress, compare before/after, and download — individually or as a ZIP.
gunzip, minus the terminal
On a machine with a shell, gunzip does this in a keystroke; on a locked-down laptop or a phone, this page is the shell-free equivalent. The reverse — making .gz files — is Gzip files; bundling many files into one compressed download is Create TAR.GZ.
Frequently asked questions
Is .gz the same as .zip?
No — gzip compresses exactly one file and holds no file list. ZIP is an archive of many. The confusion comes from tar.gz, where a tar bundle rides inside the gzip; this page recognizes that case and unpacks both layers.
Can I open huge server logs this way?
Yes — the practical ceiling is your device memory, not an upload cap, because nothing uploads. A multi-hundred-MB log.gz decompresses in seconds; the browser downloads the result like any file.
What about .bz2 and .xz files?
Same story, different compressor — and the same answer: drop them on this page or the archive tab and they decompress locally. All three families share one engine here.
Is it private?
Yes. The archive is opened and unpacked on your own device — its contents are never uploaded, and a password, if one is needed, is used locally and never transmitted. The server does nothing but deliver this page. Want proof? Run one file through, switch your connection off, and run another — it still works.
