The original file comes straight back; nothing is ever uploaded." canonical: https://compress-pro.com/extract-gz --- # Extract GZ files. > Gunzip .gz files in your browser — nothing gets uploaded. 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. **No uploads · No ads · Free & open source.** ## How it works 1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V. 2. Pick a quality or preset — or set an exact target size and let the tool find it. 3. 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](https://compress-pro.com/gzip-files); bundling many files into one compressed download is [Create TAR.GZ](https://compress-pro.com/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. ## Related tools - [Gzip files](https://compress-pro.com/gzip-files) - [Extract TAR.GZ tarballs](https://compress-pro.com/extract-tar-gz) - [Zip & Unzip files](https://compress-pro.com/zip-files) --- Part of [Compress Pro](https://compress-pro.com/) — every tool page has a markdown twin at `.md`.
