FBX to glTF Converter
Convert FBX scenes to glTF or GLB — free, private, in your browser. Optional mesh optimization for smaller, GPU-friendlier output.

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 FBX to glTF Without Uploading
Drop an FBX file onto the page and WebConverter parses it with ufbx, then writes a clean glTF 2.0 (or binary GLB) using Magnum's GltfSceneConverter. Toggle mesh optimization to re-encode meshes for the GPU vertex cache and optionally simplify them with meshoptimizer. The entire pipeline runs in WebAssembly inside your browser — your model never leaves your device.
