A tar.xz opened in a browser, with its folders listed and files taken out

Software, source code and Linux downloads often come as tar.xz, tar.bz2 or tar.zst. On Linux, tar opens them. Elsewhere you may need a program or a command. KeepSimp opens them in your browser, with nothing sent anywhere.

One tar, three ways of packing it.

Each is a tar, files one after another with their names and folders, packed smaller as one stream. The ending says how: .xz is XZ (LZMA2), .bz2 is bzip2, and .zst is Zstandard. A tar.gz is the same idea with gzip.

On a terminal, `tar -xJf` opens a tar.xz, `tar -xjf` a tar.bz2, and `tar --zstd -xf` a tar.zst, as the GNU tar manual says.

Open it in your browser.

Open Extract a tar.xz and drop the file. Its files and folders are listed, whatever the file is called. Preview what you like, then take out everything, a folder or one file.

A packed tar has no index, so reaching a file means unpacking everything before it. Taking out one file near the end takes about as long as taking out them all.

A single .xz, .bz2, .zst or .br file.

Without a tar inside, each of these holds one file, as a .gz does. It is unpacked and saved under the file's name without its ending. A .br is Brotli, which has no mark of its own at its start, so it is known by its name.

What a browser does not keep.

Files taken out get today's date, not their own, and no permissions or owner, so a script comes out as a plain file. Links inside are listed and never made. Writing into a folder works in Chrome and Edge only; other browsers save several files as one ZIP.

This tool makes tar.gz and tar, not tar.xz, tar.bz2 or tar.zst. Every Linux and Mac opens a tar.gz.
