Using the .stl to .ply converter
A standard STL supplies a triangle surface. PLY can represent additional information in other workflows, but moving the same triangles into a new container does not restore missing colors, scan measurements or original polygon topology. Check a known dimension and the surface before relying on the exported file.
Use the reverse PLY to STL converter · Compare geometry and metadata across formats
Processing limits
STEP input: 20 MB. STL, OBJ and 3MF input: 50 MB. Output is limited to 1.2 million triangles. Complex models may need simplification in the source application.
One file at a time. Processing stops after 90 seconds. Files remain in browser memory, and no conversion upload is performed. Replacing a file clears the previous result. Closing the tab releases its working data.
