ZIP, RAR, 7Z — extracted on your device, no upload
🔒 Files never leave your device — everything runs in your browser.
A .tar.gz is the Linux and developer world's answer to ZIP: GitHub release archives, research datasets, server backups, node_modules tarballs — sooner or later one lands on a Windows machine or a phone with no obvious way in. The format is actually two layers stacked: tar bundles the files into one stream, gzip compresses that stream — which is why some tools hand you a bare .tar and make you open it all over again.
Drop the archive here and both layers unwrap in one pass, entirely in your browser — the same open-source engine desktop extractors trust, with nothing sent to any server. Every file inside appears with its size and its own download button, plus one button for the lot. Plain .tar, .tar.gz, and .tgz all work, and because the archive never leaves your device, a multi-gigabyte backup costs you zero upload time.
How it works
- Drop your file
Any common format, any size. Nothing is uploaded — the tool runs in your browser.

Every file inside is listed with its own download — plus one button to grab them all. Nothing is uploaded.

Your converted file is ready on your device — nothing to wait for, nothing to delete from a server.
Frequently asked questions
What is the difference between .tar.gz, .tgz, and plain .tar?
.tgz is just shorthand for .tar.gz — identical format, shorter name. Plain .tar is the bundle without the gzip compression on top, common for local backups where speed matters more than size. All three open here the same way, with the gzip layer handled automatically when it is present.
Can a tar.gz be password-protected?
No — the tar format simply has no password or encryption feature, so every tarball opens without a prompt. When people need to protect one, they wrap it in something else, like an encrypted 7z or a GPG file; those outer wrappers are a different problem than this page solves.
Extraction gave me another .tar file — why?
Some archives genuinely contain a tarball as a file inside — Docker image exports and package caches do this a lot. Nested tarballs extract one layer at a time: download the inner .tar, drop it right back onto this page, and its contents appear.
Does this work on Windows without WSL or extra software?
Yes — that is the point. Extraction runs inside the browser itself, so Windows, macOS, phones, and locked-down work laptops all open tarballs the same way, with nothing installed and nothing sent anywhere.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
