Choose your PLY file
Select PLY from your device. The file is processed locally.
ON YOUR DEVICE
PLY to STL
Convert PLY models to STL 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 STL output
STL contains triangle geometry only. Materials, textures, scene hierarchy and animation are not retained.
Save and check your STL 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 PLY to STL?
PLY exports mesh geometry and supported vertex colors, but not textures, materials or animation. STL contains triangle geometry only. Materials, textures, scene hierarchy and animation are not retained. Check scale and orientation in the destination application. STL and OBJ files do not reliably declare units.
Will the STL file be smaller?
Not necessarily. STL contains triangle geometry only. Materials, textures, scene hierarchy and animation are not retained. Size depends on the source and settings. Compare the exported file and inspect its geometry.
Which PLY files work here?
PLY exports mesh geometry and supported vertex colors, but not textures, materials or animation. Only mesh models are supported, not CAD solids or every compressed glTF extension.
Is there a size cap for PLY to STL?
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.
