## What compression does to TAR.XZ

Repacks at maximum xz compression; the contents are byte-identical.

It's lossless, so there are no quality levels: every file comes back with identical contents, just packed more tightly.

## How to compress TAR.XZ

1. **Add your TAR.XZ files.** Drag and drop TAR.XZ files onto the compressor, paste them, or click to browse. You can add several at once.
2. **Keep the default.** TAR.XZ compression is lossless, so there's nothing to tune: every file comes back with identical contents.
3. **Compress.** Click Compress. Files are processed in an isolated cloud sandbox and are usually ready in seconds.
4. **Download.** Download each smaller TAR.XZ, or everything at once as a ZIP.

## Good to know

- xz (LZMA2) is the strongest of the common tar compressors. Repacking at its maximum preset helps when the archive was made at a lower preset.
- The contents extract byte-for-byte identical to the original.
- Because TAR.XZ compression is lossless, it can't be aimed at an exact size: the result depends entirely on what's in the file.
- TAR.XZ files are compressed in an isolated cloud sandbox created just for your job; the upload and the result are deleted automatically afterwards.
