Free Online OBJ to PLY Converter
Convert OBJ mesh geometry to binary PLY for scan comparison or mesh analysis.

The selected OBJ is read without companion MTL files or texture images. The output is binary PLY mesh data, not a texture package or animation. Colors can transfer only when they exist as supported vertex attributes; conversion does not bake textures.
PLY provides a mesh exchange file for comparing a modeled object with scan data. Use a separate output copy so the OBJ remains available for your modeling workflow.
How to Convert · OBJ → PLY
Prepare the input · OBJ
Select the OBJ mesh itself. If the project also has an MTL file and image textures, keep those originals for editing in your 3D software. Maximum file size: 50MB
Convert Now
Select the file, confirm the output format above, then start the conversion. Keep this tab open until the download button appears.
Download and check · PLY
Download the PLY and open it in a viewer that supports binary PLY. Check face count, normals and dimensions, and inspect vertex colors if the source contains them.
Why Choose Our Converter
Fast OBJ to PLY Conversion
Our OBJ to PLY converter processes files quickly using advanced algorithms specifically optimized for OBJ to PLY conversion. Convert your OBJ files to PLY format in seconds, not minutes. The OBJ to PLY conversion engine handles even complex 3D models with thousands of polygons efficiently and accurately.
Check the exported model
Only data supported by the loader and output format can transfer. Inspect the result in your target application; conversion does not repair a mesh or certify it for printing.
Browser-Based OBJ to PLY
No software download or installation needed for OBJ to PLY conversion. Our converter runs entirely in your web browser for maximum privacy, security, and convenience. Your OBJ files never leave your computer during the OBJ to PLY conversion process - everything happens locally.
100% Free OBJ to PLY Converter
Make unlimited OBJ to PLY conversions with no registration or watermark. Each source file can be up to 50 MB, and all processing runs locally in your browser.
Format Comparison
Wavefront OBJ
OBJ is a simple, widely-supported 3D model format. OBJ files store geometry data including vertices, normals, and texture coordinates. OBJ format is compatible with most 3D software.
- Universal 3D format
- Material support (.mtl)
Polygon File Format
PLY is designed for storing 3D data from 3D scanners. PLY files can include vertex colors and other properties. PLY format is commonly used in scientific visualization.
- Binary mesh export
- Vertex attributes and face indices
Choose your next conversion
PLY → OBJ
Convert a PLY scan mesh to OBJ for editing in Blender. Check that the scan has faces and plan to recreate materials after export.
OBJ → GLB
Convert an OBJ mesh to GLB for a web viewer. This single-file workflow does not import the accompanying MTL or texture images.
STL → PLY
Convert STL geometry to binary PLY for mesh inspection. Check dimensions and normals; the conversion cannot recover missing scan colors.
