Drop a .gltf below and download it repacked as a single binary .glb. Everything runs in your browser — the fastest way to turn a JSON glTF into the one-file format that viewers, engines and AR pipelines prefer.
Converted locally · never uploaded · no signup
GLB bundles the glTF's JSON, buffers and textures into a single file — easier to host, share and version.
GLB is the binary container of the same glTF 2.0 data model; geometry, materials and embedded textures carry straight through.
No upload, no processing queue — the conversion happens in browser memory and downloads immediately.
Drag the .gltf in. Self-contained files (embedded buffers) convert best.
The scene is re-exported as binary glTF 2.0 with everything embedded.
Ship one file to your web viewer, engine or client.
glTF 2.0 comes in two flavors: .gltf, a JSON file that usually references an external .bin buffer and texture images, and .glb, a binary container that packs all of it into one file. The data model is identical — GLB is simply the deployable form. Single-file assets avoid broken relative paths, CORS issues and multi-file uploads.
Because the conversion runs in your browser, it reads the .gltf file you drop. Files with embedded (base64) buffers convert perfectly; a .gltf that references external .bin or texture files can't have those fetched from your disk, so heavily externalized files may fail or lose textures. In that case export a GLB directly from your DCC tool — or embed resources first.
Yes — completely free, no signup, no limits.
No. GLB is the same glTF 2.0 data in a binary container — geometry, materials, and embedded textures are preserved.
A browser tool can't read sidecar files from your disk, so externally referenced buffers can fail to load. Use a .gltf with embedded buffers, or export GLB straight from your 3D tool.
One file instead of many: simpler hosting, no broken relative paths, smaller over the wire, and universally accepted by web viewers, engines and AR runtimes.
