TXZ Converter
FileFlip converts TXZ files into 10 other formats entirely inside your browser, using libarchive compiled to WebAssembly. The TXZ file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert a TXZ file?#
- Drop your TXZ file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert TXZ files online?#
Yes, because nothing is uploaded. FileFlip converts TXZ files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.

What is a TXZ file?#
A TXZ file is a TAR archive compressed as one xz stream under a single extension, combining tar's metadata-preserving bundling with the strongest general-purpose compression ratio of the tar pairings offered here.
Use TXZ for a source release or package where the smallest possible download size is worth slower compression.
Convert TXZ to TGZ when a tool in the chain only understands gzip, still the most universally supported tar compressor.
The TXZ file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
TXZ questions people ask#
What's the difference between .tar.xz and .txz?
Nothing; TXZ is a tar archive compressed with xz, the same content as a file named .tar.xz, just written with one extension instead of two.
Is TXZ smaller than TGZ or TBZ2?
Usually yes. xz's LZMA2 compression typically beats both gzip and bzip2 on the same data, so a TXZ archive is usually the smallest of the three tar-plus-compressor combinations, though it also takes the longest to create.
Why would software distribute a TXZ instead of just an XZ file?
XZ alone only compresses a single file or stream, so packaging an entire directory tree with permissions and structure intact requires tar first; TXZ is that tar archive compressed with xz in one step.
