To convert PLY to DAE, drop your .ply file on this page and download a .dae file seconds later. The route is PLY → GLB → DAE (parsed into a GLB scene, then exported as DAE), and geometry and materials are carried across where DAE allows.
Bringing a scan into a general modelling format lets you retopologise, retexture or composite it with other assets. PLY (.ply) is a binary or ASCII header followed by vertex and face lists. It holds point clouds and polygon faces with arbitrary per-vertex properties and is most often opened in MeshLab, CloudCompare, and Meshroom. DAE (.dae) is verbose XML following the Khronos COLLADA schema, holding polygon meshes with scene graph, cameras and lights, and is typically used in SketchUp, Blender, and Google Earth.
Under the hood, the PLY file is decoded into an in-memory scene, then serialised as DAE. The axis convention moves from not defined (it depends on the scanner or software) to either Y-up or Z-up, as declared in the file. Everything runs in your browser or an isolated, auto-purged instance, so models stay private.
.plyAbout PLY (Stanford Polygon File)
Designed to store three-dimensional data from 3D scanners, supporting polygonal facets and point clouds with per-vertex colors.
- Structure: a binary or ASCII header followed by vertex and face lists
- Materials: no real materials, only per-vertex properties
- Units: unitless (set by the scanner)
- Axis: not defined (it depends on the scanner or software)
- Opens in: MeshLab, CloudCompare, Open3D or Blender
.daeTarget format: DAE (Collada)
ISO-standard XML schema for exchanging digital assets between graphics software applications.
- Structure: verbose XML following the Khronos COLLADA schema
- Materials: COLLADA effects (Blinn, Phong, Lambert) with image references
- Units: a unit scale declared in the asset header (often meters or inches)
- Axis: either Y-up or Z-up, as declared in the file
- Opens in: SketchUp, Blender, Google Earth, Gazebo or Rviz
What happens to your data in PLY → DAE conversion
Conversion route: PLY → GLB → DAE (parsed into a GLB scene, then exported as DAE).
| Aspect | Result | Outcome |
|---|---|---|
| Geometry | Preserved | PLY stores point clouds and polygon faces with arbitrary per-vertex properties; DAE stores polygon meshes with scene graph, cameras and lights. Surfaces are retriangulated where needed and positions, normals and UV coordinates are carried across. |
| Materials | Not applicable | PLY carries no material data, so the DAE output uses a neutral default material. |
| Textures | Preserved | In PLY, texture mapping depends on a referenced image and is rarely honoured. DAE can reference or embed textures too, so images and UV mapping stay linked. |
| Vertex colours | Adapted | Per-vertex colours from PLY are kept where DAE allows them, but support in DAE is limited and some viewers will ignore them. |
| Animation | Not applicable | PLY is a static format, so the DAE result is a single static pose. |
| Units & scale | Adapted | PLY uses unitless (set by the scanner); DAE uses a unit scale declared in the asset header (often meters or inches). Check the scale in your target application, and use the Scale tool if the model looks too big or too small. |
| Orientation | Adapted | PLY is not defined (it depends on the scanner or software) and DAE is either Y-up or Z-up, as declared in the file. The converter writes a consistent orientation, but verify the up axis in your target software. |
PLY and DAE produce files of broadly similar size for the same mesh; PLY is large for dense scans, especially with colour per vertex, while DAE is large because of XML overhead.
Why convert PLY to DAE?
Why leave PLY
People most often convert from PLY when they are turning a LiDAR or photogrammetry scan into a shareable asset. Other common cases include moving a MeshLab or CloudCompare result into a game or web workflow and baking scanner colours into a more portable format. In PLY → DAE specifically, preserved: geometry and textures; adapted: vertex colours, units & scale, and orientation. PLY and DAE produce files of broadly similar size for the same mesh; PLY is large for dense scans, especially with colour per vertex, while DAE is large because of XML overhead.
Why choose DAE
DAE is the right target when you are supplying assets to engines that still expect Collada. It also fits scenarios such as importing into SketchUp, Google Earth or ROS simulations and archiving a scene with its hierarchy in an open XML standard. Bringing a scan into a general modelling format lets you retopologise, retexture or composite it with other assets.
Where the result opens
After conversion you can open the .dae file in SketchUp, Blender, Google Earth, Gazebo or Rviz.
Step-by-Step Guide: PLY → DAE
- 1
Upload your .ply file
Drag your PLY model onto the converter or click to browse. Texture mapping depends on a referenced image and is rarely honoured; no extra files are required.
- 2
Check your free quota
Free accounts can run a few conversions per day; signing in unlocks tracking of your remaining uses. No watermark is ever added.
- 3
Convert to DAE
Press the Convert to DAE button. The pipeline follows PLY → GLB → DAE (parsed into a GLB scene, then exported as DAE), which usually takes a few seconds for models under 100 MB.
- 4
Download the .dae file
Your DAE file downloads automatically. Open it in SketchUp and Blender to confirm scale and orientation.
Tips for PLY → DAE
- Scans often have millions of vertices and need decimation (PLY source).
- Z_UP files appear lying on their side in Y-up tools (DAE target).
- Always verify real-world size: PLY is unitless (set by the scanner), while DAE is a unit scale declared in the asset header (often meters or inches).
Frequently Asked Questions
How do I convert PLY to DAE without losing quality?
Upload the .ply file and press convert; the route is PLY → GLB → DAE (parsed into a GLB scene, then exported as DAE). Geometry is carried over exactly; no materials exist in the source, and textures stay linked through UV coordinates.
Does PLY to DAE conversion keep textures?
In PLY, texture mapping depends on a referenced image and is rarely honoured. DAE can reference or embed textures too, so images and UV mapping stay linked.
Why does my DAE model look the wrong size or rotation?
PLY uses unitless (set by the scanner); DAE uses a unit scale declared in the asset header (often meters or inches). Check the scale in your target application, and use the Scale tool if the model looks too big or too small. PLY is not defined (it depends on the scanner or software) and DAE is either Y-up or Z-up, as declared in the file. The converter writes a consistent orientation, but verify the up axis in your target software.
Will the DAE file be bigger or smaller than my PLY file?
PLY and DAE produce files of broadly similar size for the same mesh; PLY is large for dense scans, especially with colour per vertex, while DAE is large because of XML overhead.
What software can open the converted DAE file?
DAE files open in SketchUp, Blender, Google Earth, Gazebo or Rviz. If you need to go back, use the DAE to PLY converter.
Is it safe to upload my PLY model?
Yes. Files are processed in your browser or on isolated instances and purged right after conversion. They are never used to train AI models, and no watermark is added.
