Extract .tar.zst Files Online
Open a zstandard-compressed tarball — .tar.zst and .tzst — and save the files you need, all in your browser. No command line, no updating your archive tool.
How to extract a tar.zst file online (free)
- Drop your
.tar.zstor.tzstfile onto the box above, or click to choose it. - The zstd layer and the tar are unwrapped together, and the contents are shown as a folder tree with search and preview.
- Download one file, a ticked selection, or the lot as a
.zip,.7z,.tar.gzor.tar— or save to a folder in Chrome and Edge.
zstd tarballs, without updating anything
A .tar.zst bundles files with tar and compresses them with Zstandard — fast to make, very fast to open. It has become the default for Arch Linux packages, shows up in container tooling, and is spreading through modern backup software. Older archive managers often cannot read it. Here the 7-Zip engine, compiled to WebAssembly, reads the Zstandard stream and the tar inside it.
One step, not two
No need to run zstd -d to get a .tar and then open that separately. The tarball is unwrapped automatically and you see the files straight away. The same page handles .tar.gz, .tar.xz and .tar.bz2.
One limit in the other direction: this site can open Zstandard files but cannot create them. To repack the contents, download them as .zip, .7z or .tar.gz.
Large archives
Like every compressed tarball, a .tar.zst is a single stream that is decompressed from the start to reach a given file. Zstandard is quick to decompress, but a very large package still takes a moment. The file is read from disk in pieces and extracted data is written to your browser’s temporary storage, not held in memory.
Frequently asked questions
What is a .tar.zst file?
A .tar.zst (or .tzst) is a tar archive compressed with Zstandard (zstd). Zstd compresses fast and decompresses very fast, so it is increasingly used by Arch Linux packages and modern backups.
How do I open a tar.zst file on Windows?
Drop it on this page. The zstd layer and the tar are handled together in your browser, with no command line or extra software. Because it runs in the browser, the operating system does not matter.
Why won’t my usual archive tool open .tar.zst?
Zstd is newer than gzip or xz, so older archive managers and the tools built into some operating systems do not recognise it. This page reads zstd directly, so there is nothing to update or install.
Are my files uploaded to a server?
No. Everything runs locally in your browser with WebAssembly. Your files never leave your device, and the page keeps working offline once it has loaded.
Does it handle .tar.gz and .tar.xz too?
Yes. Gzip, xz and bzip2 tarballs open the same way, as do plain uncompressed .tar files.
Is there a size limit?
There is no fixed cap. Extracted files are written to your browser’s temporary storage on disk, so the practical limit is free disk space. In private-browsing modes without that storage, memory is used instead and large archives may fail.
