GLB to OBJ
Convert GLB models to OBJ 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 OBJ output
OBJ import and export preserve mesh geometry. This tool does not carry OBJ MTL materials, textures or animation.
Save and check your OBJ 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 OBJ?
GLB packages supported scene data into one binary glTF file. Unsupported extensions may not import. OBJ import and export preserve mesh geometry. This tool does not carry OBJ MTL materials, textures or animation. Check scale and orientation in the destination application. STL and OBJ files do not reliably declare units.
Will the OBJ file be smaller?
Not necessarily. OBJ import and export preserve mesh geometry. This tool does not carry OBJ MTL materials, textures or animation. 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 OBJ?
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.
