Choose your glTF file
Select the glTF together with its local BIN and texture files.
ON YOUR DEVICE
glTF to OBJ
Convert glTF 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 glTF to OBJ?
glTF uses JSON scene data. Include referenced BIN and texture files when opening a source glTF; remote assets are blocked. 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 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 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.
