3DS to XZ Converter
Processing entirely on your device — large files may take a moment.
Autodesk 3DS Mesh and XZ Compressed File exist for different jobs: 3DS is the original 3D Studio mesh format from 1990 — chunk-based binary that game pipelines and asset stores still carry by the terabyte. Unpack XZ into ZIP/TAR for tools that cannot read LZMA2.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the 3DS format
3DS is the chunk-based binary mesh format of Autodesk's original 3D Studio (1990). Entire generations of game assets, product visualizations and Turbosquid listings live in it, and its chunk structure (every block self-describing with ID and length) kept it forward-compatible for two decades.
Three.js ships a TDS parser, so 3DS files convert straight to glTF/OBJ in the browser — meshes, materials and UVs survive; lights and keyframers of the original format are skipped as display-only.
+Strengths
- ✓Ubiquitous legacy asset format
- ✓Self-describing chunk structure
- ✓Direct browser-side conversion
!Limitations
- −No animation or skeleton data
- −8.3 filenames inside
- −Vertex limit per mesh (~64k)
About the XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux
Why convert 3DS to XZ?
There is a concrete reason this conversion exists: No animation or skeleton data XZ sidesteps that — Highest common ratio If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this 3DS to XZ 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.
Is there a file size limit for 3DS to XZ?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the 3DS file.
