ON YOUR DEVICE
OBJ to PLY
Convert OBJ models to PLY 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 PLY output
PLY exports mesh geometry and supported vertex colors, but not textures, materials or animation.
Save and check your PLY 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 OBJ to PLY?
OBJ import and export preserve mesh geometry. This tool does not carry OBJ MTL materials, textures or animation. PLY exports mesh geometry and supported vertex colors, but not textures, materials or animation. Check scale and orientation in the destination application. STL and OBJ files do not reliably declare units.
Will the PLY file be smaller?
Not necessarily. PLY exports mesh geometry and supported vertex colors, but not textures, materials or animation. Size depends on the source and settings. Compare the exported file and inspect its geometry.
Which OBJ files work here?
OBJ import and export preserve mesh geometry. This tool does not carry OBJ MTL materials, textures or animation. Only mesh models are supported, not CAD solids or every compressed glTF extension.
Is there a size cap for OBJ to PLY?
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.
