OBJ to glTF Converter
Convert Wavefront OBJ models to modern glTF or GLB — free, private, with optional mesh optimization.

FBX is loaded via ufbx, other formats via Assimp
Supported: FBX, OBJ, DAE, PLY, STL, GLTF, GLB, 3DS, LWO, BLEND, X
.glb is a single compact binary file; .gltf is JSON with embedded buffers (easier to inspect).
Re-orders vertices and triangles for vertex-cache locality, overdraw and vertex fetch. Produces smaller, faster files.
Reduce triangle count by the chosen percentage. 0% keeps every triangle.
Re-encode embedded textures as supercompressed KTX2 for tiny GPU uploads. Wiring is in place; the encoder module ships in a follow-up.

Convert OBJ to glTF in Your Browser
Drop a Wavefront OBJ (with its MTL material file if present) and WebConverter reads it via Assimp, then writes glTF 2.0 / GLB with Magnum's GltfSceneConverter. Enable optimization to re-encode meshes for the GPU vertex cache and optionally simplify them with meshoptimizer — useful for shrinking large CAD exports for the web.
