Add your XZ file
Drop one or more .xz files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
XZ to TAR
Repacking a .xz archive as .tar moves the same files into a container with different compression and compatibility trade-offs. Free, private, and validated — the file never leaves your browser.

Repacking a .xz archive as .tar moves the same files into a container with different compression and compatibility trade-offs. An .xz file holds a single stream compressed with LZMA2, delivering some of the best ratios of any general-purpose compressor. It follows the Unix one-stream philosophy — pair it with tar as .tar.xz when multiple files need archiving.
A .tar file is a tape archive: many files and directories laid end to end in a single uncompressed stream, preserving Unix permissions, owners, and symlinks. It bundles but does not compress — that job is delegated to gzip, bzip2, or xz layered on top. For this route the practical draw is exact preservation of Unix metadata that other archive formats drop and dead-simple, fully streamable structure — balanced against uncompressed on its own, so bare .tar files are as large as their contents, which is worth knowing before you commit a large batch.
Why convert XZ to TAR?
The practical trigger for this conversion is usually a mismatch: with .xz, slow and memory-intensive to compress; huge dictionaries can strain small devices even on decompression. Switching to .tar buys you exact preservation of Unix metadata that other archive formats drop, which is why it is the better fit for source code distribution across the Unix world. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
XZ vs TAR at a glance
| Aspect | XZ stream (.xz) | TAR archive (.tar) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | lZMA2 chunks the LZMA stream so state can reset, enabling multithreaded compression and better error recovery | each file gets a 512-byte header block (name, mode, uid/gid, size, mtime, type) followed by its data padded to 512-byte boundaries |
| Strongest at | software release tarballs where download size matters most | source code distribution across the Unix world |
| Weak spot | slow and memory-intensive to compress; huge dictionaries can strain small devices even on decompression | uncompressed on its own, so bare .tar files are as large as their contents |
Pick TAR as the output
Select .tar in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TAR is selectable, the route is real and validated.
Convert on your device
Press Convert. Extraction and repacking use WebAssembly builds of real archive engines (libarchive and fflate) running in your browser.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TAR file. Outputs keep the original filename with the .tar extension.
XZ to TAR questions, answered
Will converting XZ to TAR lose quality?
Since xz is container-oriented and tar is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .tar itself requires.
Is it private to convert XZ files here?
Yes — the .xz file is processed inside your browser tab and never uploaded. Extraction and repacking use WebAssembly builds of real archive engines (libarchive and fflate) running in your browser. Close the tab and the file is gone from memory.
Where will the TAR file work?
Every Linux distribution, macOS, and the BSDs ship tar as a core utility, and Windows 10 and later include bsdtar at the command line. Graphical tools like 7-Zip open tarballs too, though they may need two passes for compressed variants.
Will the TAR file be bigger or smaller than my XZ?
It depends on the content: each file gets a 512-byte header block (name, mode, uid/gid, size, mtime, type) followed by its data padded to 512-byte boundaries. Convert one representative file first and compare before batch-processing a large set.
