A .tar.xz (also written .txz) is a tar archive squeezed with XZ / LZMA2 compression, common for Linux source releases and packages. Open one right in your browser, list the files inside, and download them — or repackage everything into a standard .zip. No command line, no installs, no uploads, no sign-up.
Drag your archive onto the box above or click it to pick a .tar.xz or .txz file. The tool opens it in your browser, lists every file with its size, and lets you save any file on its own or choose Download as .zip to repackage the whole archive into a standard ZIP that opens natively on Windows and macOS.
The decoding runs on your own machine: the .tar.xz is handed to libarchive, compiled to WebAssembly and driven from a background worker so the page stays responsive, with nothing to upload and no software to install. It unpacks the XZ compression and reads the tar inside in one pass, so you get straight to the files.
That worker pulls roughly 1 MB of WebAssembly from this site, and that decoder is the only thing this page ever requests. The honest test takes a few seconds: open your browser’s network panel, drop in a .tar.xz, and read the list. Every request is for the decoder; your archive is not among them.
This tool is for .tar.xz / .txz archives — a tar wrapped in XZ. A plain single-file .xz that does not contain a tar is a different case and is not handled here. No file size limit is imposed; the practical cap is the free RAM on your device, since the archive and its contents sit in memory while you work.
