GLB to glTF
Convert GLB models to glTF 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 glTF output
glTF uses JSON scene data. Include referenced BIN and texture files when opening a source glTF; remote assets are blocked.
Save and check your glTF 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 GLB to glTF?
GLB packages supported scene data into one binary glTF file. Unsupported extensions may not import. glTF uses JSON scene data. Include referenced BIN and texture files when opening a source glTF; remote assets are blocked. Check scale and orientation in the destination application. STL and OBJ files do not reliably declare units.
Will the glTF file be smaller?
Not necessarily. glTF uses JSON scene data. Include referenced BIN and texture files when opening a source glTF; remote assets are blocked. Size depends on the source and settings. Compare the exported file and inspect its geometry.
Which GLB files work here?
GLB packages supported scene data into one binary glTF file. Unsupported extensions may not import. Only mesh models are supported, not CAD solids or every compressed glTF extension.
Is there a size cap for GLB to glTF?
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.
