How to Convert TAR.XZ to Any Format
- Upload Your TAR.XZ File: Drag and drop your
.tar.xzarchive or click "Add Files". Batch is supported — drop in several tarballs at once and each is converted separately. - Pick an Output Format: Choose the target archive from the format selector — ZIP, 7Z, TAR, RAR, TAR.GZ, TAR.BZ2, TGZ, TB2, or TZ2. ZIP is selected by default for the broadest Windows and macOS compatibility.
- Choose How Multiple Files Are Packed (Optional): Under Advanced Options, set the combine mode — "Individual Archives" makes one output per source tarball, or "Single Archive" merges several uploaded tarballs into one combined archive.
- Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert a TAR.XZ File?
A .tar.xz file is a TAR bundle — the classic Unix way of packing many files and their permissions into one stream — that has then been compressed with xz. The xz format (specification released in January 2009) is built on the LZMA/LZMA2 algorithm, the same family used inside 7-Zip. In independent benchmarks it consistently reaches a higher compression ratio than gzip or bzip2 on the same data, which is why it has become common for Linux source tarballs and software packages. The catch is that compressing with xz is slow and memory-hungry; decompression, by contrast, is fast.
People convert away from TAR.XZ mostly for compatibility and speed:
- Opening it on Windows or macOS — neither extracts
.tar.xzout of the box, so TAR.XZ to ZIP produces a file that File Explorer and Finder open with a double-click. 7Z is the alternative when you want to keep a high ratio for someone who has 7-Zip installed. - Faster, more portable decompression — gzip is everywhere and decompresses quickly, so TAR.XZ to TAR.GZ trades some size for a tarball that almost any Unix system unpacks without an xz binary present.
- Stripping compression entirely — converting to plain TAR removes the xz layer, handy when a build script or tool expects an uncompressed archive or you plan to re-compress with different settings.
- Matching a tool that expects a specific format — some pipelines, uploaders, or legacy utilities only accept RAR, bzip2, or a particular extension; repackaging avoids "unsupported archive" errors without manually extracting and re-zipping.
Converting re-packs the same files into the new container — your filenames, folder structure, and contents come through unchanged. The only thing that changes is the wrapper and the compression used to store it.
TAR.XZ vs. Common Conversion Targets
| Format | Compression | Native on Windows/macOS | Typical ratio | Best for |
|---|---|---|---|---|
| TAR.XZ | xz (LZMA2) | No | Highest of these | Smallest size; Linux source/package distribution |
| 7Z | LZMA / LZMA2 | No (needs 7-Zip) | Very high | High ratio in a Windows-friendly container |
| ZIP | Deflate | Yes | Lowest | Sharing anywhere with no extra software |
| TAR.GZ | gzip (Deflate) | No | Moderate | Fast, near-universal Unix decompression |
| TAR.BZ2 | bzip2 | No | High | Older Unix toolchains; better ratio than gzip |
| TAR | none | No | None (stored) | A raw bundle to re-compress or feed a build step |
Compression Methods Compared
| Method | Used by | Ratio | Compress speed | Decompress speed | Memory |
|---|---|---|---|---|---|
| xz / LZMA2 | .tar.xz, .xz | Highest | Slow | Fast | High |
| LZMA / LZMA2 | .7z | Very high | Slow | Fast | Moderate-high |
| bzip2 (BWT) | .tar.bz2 | High | Moderate | Moderate | Moderate |
| gzip / Deflate | .tar.gz, .tgz | Moderate | Fast | Fast | Low |
| Deflate | .zip | Moderate-low | Fast | Fast | Low |

Frequently Asked Questions
What is a TAR.XZ file and what opens it?
A TAR.XZ file is a TAR archive that has been compressed with xz (LZMA2). On Linux it opens with tar -xf file.tar.xz or the desktop archive manager; on macOS and Windows the operating system does not handle it natively, so you need a tool like 7-Zip, The Unarchiver, or an online converter. Converting it to ZIP is the simplest way to make it open with a plain double-click on any desktop.
Why is xz smaller than gzip, and when does that matter?
xz uses the LZMA2 algorithm with a much larger dictionary than gzip's Deflate, so it finds more redundancy and produces a smaller file — in published benchmarks it consistently beats both gzip and bzip2 on ratio. The trade-off is speed: xz is markedly slower and uses more memory to compress, though it decompresses quickly. That makes xz ideal for files compressed once and downloaded many times (like a Linux source release), and gzip's TAR.GZ a better pick when you compress often or need the fastest, most portable extraction.
Will converting TAR.XZ to ZIP make the file bigger?
Usually yes, modestly. ZIP uses the older Deflate algorithm, which compresses less tightly than xz, so the ZIP is typically larger than the original .tar.xz for the same contents. You are trading some size for the convenience of a format that opens natively on Windows and macOS. If keeping the size down matters more than universal compatibility, convert to 7Z instead — it uses the same LZMA family as xz.
Do I lose any files or permissions when I convert?
Your filenames, folder structure, and file contents are preserved across every conversion. Unix permission bits and ownership stored in the TAR layer carry through to other TAR-based targets (TAR, TAR.GZ, TAR.BZ2) cleanly; ZIP and RAR use a different metadata model, so fine-grained Unix permissions may not survive a conversion to those formats — the files themselves are intact, but exact chmod bits can be normalized.
Is TAR.XZ to TAR.GZ a good idea for sharing on Linux?
Often, yes. gzip is installed on practically every Unix-like system and decompresses faster than xz, so TAR.GZ is the safest tarball to hand to a machine you don't control or an older toolchain. You give up some compression — the TAR.GZ will be larger than the TAR.XZ — but you gain near-universal, fast extraction with no xz binary required.
Is xz compression the same as what 7-Zip uses?
They're close relatives. Both xz and 7-Zip's default .7z are built on the LZMA / LZMA2 algorithm, so they reach similar compression ratios. The difference is scope: .xz compresses a single stream, which is why it's paired with tar — tar bundles many files into one stream first, then xz squeezes that stream. A .7z file is a complete archive format that holds the file list and directory structure itself, no tar needed. Converting TAR.XZ to 7Z therefore keeps a comparable ratio in a container that 7-Zip on Windows opens directly.
What's the difference between .tar.xz, .txz, and a plain .xz file?
.tar.xz and .txz are the same thing — .txz is just the shorthand extension for a tar archive compressed with xz. A plain .xz file is different: it's a single file or stream compressed with xz and no tar layer, so it cannot hold a folder of files or preserve directory structure on its own. If you need to pack many files together, you want the tar-plus-xz combination (.tar.xz / .txz); a bare .xz is for compressing one file at a time.
How large a TAR.XZ can I convert, and is it private?
Free uploads are limited to 400 MB per file (paid plans raise the cap), so larger archives need splitting first. In our testing, a 120 MB .tar.xz of mixed source code converted to ZIP in a few seconds once the upload completed, producing a roughly 150 MB ZIP. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up and no watermark, and your archives are never shared or made public.
