Convert OBJ, STL, FBX, DAE, PLY and 40+ formats to glTF/GLB for the web — on your device. The result is a GLTF-BINARY, GLTF+JSON file you download directly.
How it works
ffmpeg.wasm + libvips-wasm + pdf-lib + sheetjs + mammoth, with a routing layer that picks the best engine per pair. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
