OBJ to PLY
Convert single-file OBJ geometry to binary PLY. Object positions are baked into the output mesh, using millimeters and Z up.

01 / HOW IT WORKS
Open, inspect, then use your result.
- 01
Open your file
Choose, drop or paste your OBJ file. All three input methods use the same local checks.
- 02
Look from every angle
Orbit, zoom and switch between standard views. Read the dimensions and object count beside the model.
- 03
Download the converted file
After conversion, download PLY. Open the result in your destination software and check the units before use.
02 / TRY IT YOURSELF
A real file. A result you can check.
This original four-hole plate measures 80 × 50 × 8 mm. The sample uses the input format for this page. Use the default unit and axis settings to reproduce those dimensions.

03 / FORMAT & USE
OBJ to PLY
Convert single-file OBJ geometry to binary PLY. Object positions are baked into the output mesh, using millimeters and Z up. The size report uses millimeters; input unit and axis controls determine how the source file is interpreted.
What this viewer supports
Exports a merged triangle mesh, not an assembly hierarchy. Texture images, transparency and full PBR materials are not retained. OBJ input does not load external MTL files. GLB input must be static and self-contained.
Supports files up to 32 MiB, 1 million triangles and 2,000 mesh objects. For larger assemblies, export only the parts you need.
04 / QUESTIONS
Know your input. Understand your output.
Does PLY preserve all materials and separate objects?
No. Geometry is combined in world space. Supported vertex colors and basic material colors are written as vertex RGB, but textures and object hierarchy are not preserved.
Do I need an account or credits?
No. These tools are free and run in your browser. No account, subscription or credits are required.
Is my model uploaded?
No. Your selected file is read and processed in this browser. The page downloads its CAD engine and public samples, but does not upload your model. Refreshing or leaving the page clears the current file from the tool.
How are units and orientation handled?
Dimensions use millimetres with Z up. GLB uses metres with Y up; exported STL is mm/Z-up and OBJ is mm/Y-up.
Can I paste a file from my computer?
Copy a file in your file manager, then paste here. Your browser must expose the clipboard as a file; a copied path or text will not open a model.
