How to Convert a STL File to GLB/glTF on Mac

The STL (Stereolithography) format is the standard for 3D printing, used to describe an object's geometry as a triangle mesh. Converting STL to GLB/glTF lets you display your 3D models on the web or in real-time applications.

Why Convert STL to GLB/glTF?

Convert STL to GLB/glTF with Eyemesh

Step 1 — Open the STL File

Launch Eyemesh and open your STL file: drag and drop the file into the window, or use File > Open (Cmd+O). STL files contain no textures — the model will display with a default material.

Step 2 — Check the Model

Inspect your model in the 3D view. Check that textures and materials display correctly. If textures are missing, use the Texture Manager to reassign them manually.

Step 3 — Export to GLB/glTF

Click the export icon in the toolbar, select the GLB or glTF format, choose a save location, and confirm. The file is ready to embed on the web or in a real-time 3D application.

What Is the STL Format?

STL (Stereolithography) is a format created by 3D Systems for 3D printing. It describes only the surface geometry of an object as a triangulated mesh, with no color, texture, or material. Available in ASCII or binary, it is the most widespread format for additive manufacturing and rapid prototyping.

What Is the GLB/glTF Format?

glTF (GL Transmission Format) is an open Khronos Group format, often called the "JPEG of 3D". Its binary version GLB packages geometry, PBR materials, textures, and animations into a single file. It is the standard format for web 3D (Three.js, Babylon.js, model-viewer) and cross-platform AR/VR experiences.

Download Eyemesh on the Mac App Store and convert your STL files to GLB/glTF in just a few clicks.
