OBJ to PLY Converter
Processing entirely on your device — large files may take a moment.
Wavefront OBJ Model and PLY Point/Mesh Model exist for different jobs: OBJ is the veteran plain-text 3D format from Wavefront: vertices, faces and texture coordinates in a human-readable file that almost every 3D package imports. Scanner exports usually arrive as PLY; converting to STL makes them printable.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How OBJ compares to PLY
| OBJ | PLY | |
|---|---|---|
| Structure | Mesh + UVs (+ groups) | Point cloud or mesh |
| Materials | Via separate MTL file | Vertex colors only |
| Compatibility | Universal exchange veteran | Scanning/scientific stacks |
| Best for | Static model exchange | Scans and point clouds |

About the OBJ format
OBJ (Wavefront, 1990s) is the veteran of 3D model exchange: a text file of vertices, UV coordinates and faces, optionally paired with an MTL material file and texture images. It predates every modern pipeline yet still opens everywhere, which keeps it as the default export of modeling tutorials, asset stores and scan software.
It is static by design — no animation, no rigging, no scene hierarchy beyond groups — and MTL's habit of referencing textures by relative path means a lonely .obj file often shows up untextured. For static meshes with appearance, it remains a dependable common ground.
+ Strengths
- ✓Opens in every 3D application, old and new
- ✓Text-readable and easy to generate programmatically
- ✓Carries UVs and materials via MTL
! Limitations
- −No animation, rigging or hierarchy
- −Texture references break when files travel alone
- −Text format is bulky for dense meshes
About the PLY format
PLY (Stanford Polygon File Format) grew out of the Stanford scanning projects of the 1990s and became the standard output of 3D scanners and photogrammetry. Its superpower is custom vertex properties: beyond x/y/z and faces, a PLY can attach color, normals, confidence and scanner-specific channels to every point — which is why point clouds live in it.
It handles meshes too (binary or ASCII), but rendering ecosystems care little for it — no PBR materials, no hierarchy, no animation. Typical workflow: scan or photogrammetry outputs PLY, you clean it, then convert to GLB/OBJ for visualization or STL for printing.
+ Strengths
- ✓Standard of scanning and photogrammetry
- ✓Custom per-vertex attributes (color, normals, confidence)
- ✓Handles dense point clouds efficiently
! Limitations
- −No materials, hierarchy or animation
- −Sparse support in viewers and engines
Why convert OBJ to PLY?
There is a concrete reason this conversion exists: No animation, rigging or hierarchy PLY sidesteps that — Standard of scanning and photogrammetry If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this OBJ to PLY converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will my model look the same as a GLB?
Geometry, hierarchy and standard materials convert faithfully. Note that Draco-compressed GLB files and exotic extensions are not supported — export those as plain GLB from your original tool first.
Will my PLY model keep its colors and textures?
Only if PLY can store them. Geometry converts faithfully; appearance data survives only when the target format has a place to put it. For full materials, GLB is usually the right target.
How large can the OBJ file be?
Everything runs on your device, so memory is the only ceiling. Dense meshes with millions of triangles convert fine on a desktop computer, just over a slightly longer coffee break.
