Choose your glTF file
Select the glTF together with its local BIN and texture files.
ON YOUR DEVICE
glTF to GLB
Convert glTF models to GLB on your device. Preview the mesh, then check the exported model.
Choose a 3D model
GLB, glTF, OBJ, STL or PLY · Device-dependent capacity
Three simple steps
Prepare GLB output
GLB packages supported scene data into one binary glTF file. Unsupported extensions may not import.
Save and check your GLB file
Check scale and orientation in the destination application. STL and OBJ files do not reliably declare units.
Common questions
What changes when I convert glTF to GLB?
glTF uses JSON scene data. Include referenced BIN and texture files when opening a source glTF; remote assets are blocked. GLB packages supported scene data into one binary glTF file. Unsupported extensions may not import. Check scale and orientation in the destination application. STL and OBJ files do not reliably declare units.
Will the GLB file be smaller?
Not necessarily. GLB packages supported scene data into one binary glTF file. Unsupported extensions may not import. Size depends on the source and settings. Compare the exported file and inspect its geometry.
Which glTF files work here?
glTF uses JSON scene data. Include referenced BIN and texture files when opening a source glTF; remote assets are blocked. Only mesh models are supported, not CAD solids or every compressed glTF extension.
Is there a size cap for glTF to GLB?
There is no fixed file-size quota. Process one main file at a time. Your device memory and browser determine practical capacity. Large selections show a warning that you can continue past.
