3MF to TXZ Converter
Processing entirely on your device — large files may take a moment.
Convert TXZ exactly like TAR.XZ. If your files are still in 3MF format, this page is the shortcut: 3MF is the modern 3D-printing format: an OPC zip of XML model parts with materials and units — STL's successor designed by Microsoft, HP and the printing industry.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the 3MF format
3MF is what STL should have been: an OPC zip containing XML model parts with real units, materials, colors and print settings — designed by a consortium (Microsoft, HP, Ultimaker, Prusa) to fix STL's missing-everything problem. Modern slicers prefer it.
The XML model inside parses straight into a three.js scene, so 3MF converts to glTF for previews or OBJ for DCC tools without ever opening a slicer.
+Strengths
- ✓Units, materials and metadata included
- ✓Industry-backed open standard
- ✓Modern slicers prefer it over STL
!Limitations
- −Older printers still want STL
- −XML verbosity for huge meshes
- −Extension namespaces vary by vendor
About the TXZ format
TAR.XZ pairs the tar container with XZ (LZMA2) compression — the highest-ratio member of the tar family and the de-facto release format of modern Linux distributions. The same source tree that lands 5% smaller than TAR.BZ2 and 20% smaller than TAR.GZ is why kernel.org and GNU mirrors standardised on it.
The trade is CPU time: XZ compresses slow (dictionary sizes up to 64 MB) but decompresses fast, which makes it ideal for one-time releases that get downloaded millions of times. When you need speed instead, TAR.GZ or TAR.ZSTD are the neighbouring picks.
+Strengths
- ✓Best compression ratio of the tar family
- ✓Standard release artifact of Linux distros
- ✓Fast decompression despite slow compression
!Limitations
- −Compression is CPU-heavy and single-threaded by default
- −Larger toolchain footprint than gzip on tiny systems
Why convert 3MF to TXZ?
There is a concrete reason this conversion exists: Older printers still want STL TXZ sidesteps that — Best compression ratio of the tar family If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this 3MF to TXZ converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will my model look the same as a GLB?
Geometry, hierarchy and standard materials convert faithfully. Note that Draco-compressed GLB files and exotic extensions are not supported — export those as plain GLB from your original tool first.
Does the scale or orientation of the model change?
Vertex data is converted as-is. Formats without a unit system (like STL) are interpreted as millimeters by most 3D-printing tools — scale before converting if your model uses different units.
Will my TXZ model keep its colors and textures?
Only if TXZ can store them. Geometry converts faithfully; appearance data survives only when the target format has a place to put it. For full materials, GLB is usually the right target.
