Convert DAE to GLTF Online (Free & Secure)
To convert DAE to glTF, drop your .dae file on this page and download a .gltf file seconds later. The route is DAE → GLB → glTF (parsed into a GLB scene, then exported as glTF), and geometry and materials are carried across where glTF allows.

To convert DAE to glTF, drop your .dae file on this page and download a .gltf file seconds later. The route is DAE → GLB → glTF (parsed into a GLB scene, then exported as glTF), and geometry and materials are carried across where glTF allows.
Legacy and DCC formats are heavy and awkward on the web; converting them gives you a compact asset that loads in any modern browser. DAE (.dae) is verbose XML following the Khronos COLLADA schema. It holds polygon meshes with scene graph, cameras and lights and is most often opened in SketchUp, Blender, and Google Earth. glTF (.gltf) is a JSON scene description that references separate .bin and image files, holding indexed triangle meshes with optional morph targets and skins, and is typically used in Blender, Visual Studio Code glTF tools, and three.js.
Under the hood, the DAE file is decoded into an in-memory scene, then serialised as glTF. The axis convention moves from either Y-up or Z-up, as declared in the file to Y-up, right-handed. Everything runs in your browser or an isolated, auto-purged instance, so models stay private.
.daeAbout 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
.gltfTarget format: glTF (JSON)
Standard open-source 3D scene description format using JSON with external or embedded buffers and textures.
- Structure: a JSON scene description that references separate .bin and image files
- Materials: PBR metallic-roughness materials
- Units: meters (fixed by the glTF specification)
- Axis: Y-up, right-handed
- Opens in: Blender, Cesium, three.js or any glTF 2.0 viewer
What happens to your data in DAE → glTF conversion
Conversion route: DAE → GLB → glTF (parsed into a GLB scene, then exported as glTF).
| Aspect | Result | Outcome |
|---|---|---|
| Geometry | Preserved | DAE stores polygon meshes with scene graph, cameras and lights; glTF stores indexed triangle meshes with optional morph targets and skins. Surfaces are retriangulated where needed and positions, normals and UV coordinates are carried across. |
| Materials | Preserved | DAE uses COLLADA effects (Blinn, Phong, Lambert) with image references and glTF can represent the same information, so base colour and surface settings are preserved. |
| Textures | Preserved | In DAE, textures are referenced as external image files. glTF can reference or embed textures too, so images and UV mapping stay linked. |
| Vertex colours | Preserved | Per-vertex colours in DAE are written to glTF as vertex colour data. |
| Animation | Preserved | DAE provides skeletal animation, controllers and kinematics; glTF supports it as well, so clips can travel with the model. |
| Units & scale | Adapted | DAE uses a unit scale declared in the asset header (often meters or inches); glTF uses meters (fixed by the glTF specification). Check the scale in your target application, and use the Scale tool if the model looks too big or too small. |
| Orientation | Adapted | DAE is either Y-up or Z-up, as declared in the file and glTF is Y-up, right-handed. The converter writes a consistent orientation, but verify the up axis in your target software. |
Expect the glTF file to be roughly 2.9x smaller than the DAE source, since glTF is similar to GLB, but split across several files.
Why convert DAE to glTF?
Why leave DAE
People most often convert from DAE when they are opening a SketchUp or robotics export in a modern pipeline. Other common cases include retiring an XML-heavy archive into a compact format and making a legacy Collada asset viewable on the web. In DAE → glTF specifically, preserved: geometry, materials, textures, vertex colours, and animation; adapted: units & scale and orientation. Expect the glTF file to be roughly 2.9x smaller than the DAE source, since glTF is similar to GLB, but split across several files.
Why choose glTF
glTF is the right target when you are debugging materials and node hierarchies. It also fits scenarios such as keeping a human-readable scene you can diff in version control and feeding pipelines that expect separate buffers. Legacy and DCC formats are heavy and awkward on the web; converting them gives you a compact asset that loads in any modern browser.
Where the result opens
After conversion you can open the .gltf file in Blender, Cesium, three.js or any glTF 2.0 viewer.
Step-by-Step Guide: DAE → glTF
- 1
Upload your .dae file
Drag your DAE model onto the converter or click to browse. Textures are referenced as external image files; zip the model with its textures and companion files if you want them included.
- 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 glTF
Press the Convert to glTF button. The pipeline follows DAE → GLB → glTF (parsed into a GLB scene, then exported as glTF), which usually takes a few seconds for models under 100 MB.
- 4
Download the .gltf file
Your glTF file downloads automatically. Open it in Blender and Visual Studio Code glTF tools to confirm scale and orientation.
Tips for DAE → glTF
- External texture paths break when files are moved (DAE source).
- Relative paths to .bin and texture files break when the files are separated (glTF target).
- Always verify real-world size: DAE is a unit scale declared in the asset header (often meters or inches), while glTF is meters (fixed by the glTF specification).
- Since DAE is much heavier than glTF, converting is also a good way to shrink your asset.
Frequently Asked Questions
How do I convert DAE to glTF without losing quality?
Upload the .dae file and press convert; the route is DAE → GLB → glTF (parsed into a GLB scene, then exported as glTF). Geometry is carried over exactly; materials are preserved, and textures stay linked through UV coordinates.
Does DAE to glTF conversion keep textures?
In DAE, textures are referenced as external image files. glTF can reference or embed textures too, so images and UV mapping stay linked.
Why does my glTF model look the wrong size or rotation?
DAE uses a unit scale declared in the asset header (often meters or inches); glTF uses meters (fixed by the glTF specification). Check the scale in your target application, and use the Scale tool if the model looks too big or too small. DAE is either Y-up or Z-up, as declared in the file and glTF is Y-up, right-handed. The converter writes a consistent orientation, but verify the up axis in your target software.
Will the glTF file be bigger or smaller than my DAE file?
Expect the glTF file to be roughly 2.9x smaller than the DAE source, since glTF is similar to GLB, but split across several files.
What software can open the converted glTF file?
glTF files open in Blender, Cesium, three.js or any glTF 2.0 viewer. If you need to go back, use the glTF to DAE converter.
Is it safe to upload my DAE 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.
