Convert glTF files to STL in seconds. Geometry, UVs and materials are carried over where STL supports them, and the model lands the right way up.
Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.
STL is already selected. You can switch to any other output from the menu.
Click Convert and your STL file is ready in seconds. Download it straight away.
glTF is the open Khronos standard for delivering 3D content on the web. The .gltf version is human-readable JSON that points to a separate .bin file for geometry and to image files for textures.
STL describes a surface as a list of triangles, with no colour, material or unit information. It is the default file for 3D printing and is exported by almost every CAD and modelling program.
If your glTF has companion files (.bin and texture images), select them together with the glTF file so materials come through.
Colours and texture coordinates are carried over when STL supports them. STL does not store textures, so only the geometry carries over.
No. glTF and STL may use different "up" directions, and we rotate the model so it stands the same way in your software.
