GLTF to GLB FAQ

Is this GLTF to GLB converter free?

Yes. UniConvert does not require an account for GLTF → GLB. Ads may appear to keep the site free.

Do you store my GLTF files?

Files for this pair are sent to the free conversion provider for processing and are not stored by UniConvert afterward.

What is the difference between .gltf and .glb?

.gltf is treated as the input format and .glb as the output. Use this page when you specifically need GLTF → GLB rather than a generic upload form.
