Convert OBJ to GLB

OBJ → GLB: what you should know

OBJ is a veteran, universal text format supported by practically every 3D application. It's used mostly in interchange between 3D apps (Blender, Maya, 3ds Max), texturing, rendering, and it stores geometry, UVs and normals (materials live in a separate MTL file). GLB, on the other hand, is the binary flavor of glTF, the modern standard for 3D on the web: a single file with everything inside — the format expected by the web (Three.js, model-viewer), AR, games, online stores, Sketchfab.

This tool converts your OBJ files to GLB right in the browser: no queue, no artificial size limit and, above all, your file is never uploaded to any server. Geometry is preserved with the exact coordinates and scale of the original — important if the model is going to be printed or measured.

Keep in mind: If the OBJ referenced MTL materials, they aren't included. If you need to keep that data, convert to a format that supports it (GLB keeps materials and textures; PLY keeps vertex colors).
