Convert 3DS to STL online

Drop a .3ds file to turn it into STL. You see the model in 3D before converting, and the file never leaves your device.

What is kept when converting 3DS to STL

Geometry: Kept
Materials: Lost
Textures: Lost
Animation: Not in 3DS
Scene hierarchy: Lost

About 3DS

Autodesk 3D Studio

3DS is the legacy Autodesk 3D Studio format: meshes, basic materials and texture references. Many old asset libraries still ship it.

About STL

Stereolithography

STL describes only the surface of a model as triangles — no colors, materials or textures. It is the default format for 3D printing and slicers.

How it works

01
Drop the .3ds file (with its textures or .bin/.mtl files, if any).
02
Check the model in the 3D preview; STL is already selected.
03
Click “Convert” and the .stl file downloads.

Questions

Is the 3DS to STL converter free?+

Yes, without limits, sign-up or watermark.

Is my 3DS file uploaded?+

No. The 3DS file is read and converted in your browser; nothing is sent to a server.

Why are textures missing after converting 3DS?+

Textures stored as separate files must be selected together with the model. STL keeps them only if the format supports textures.
