XZ Compress

Compress with XZ (native CLI required).

XZ Compress
Not supported in the browser.
XZ uses a native container/compression format (XZ-framed LZMA) that has no reliable pure-JavaScript encoder or decoder. Use the command line:
xz -z # compress | xz -d # decompress
The other formats (Brotli, LZMA, Zstandard, Tar) on this site work fully in-browser.
