Convert DAE to OFF
Free DAE to OFF converter that runs in your browser. See real dimensions before you download.
How to convert DAE to OFF
- Drop your DAE file (with its textures, if separate) onto the converter — it opens in your browser, nothing is uploaded.
- Check the preview and the dimensions in mm; fix units or the up axis in “Units & orientation” if the size or orientation looks wrong.
- Choose OFF as the output and click Convert. Several files download as one ZIP.
What carries over from DAE to OFF
| DAE | OFF | Result | |
|---|---|---|---|
| Colour / materials | Yes | No | Dropped |
| Textures | Yes | No | Dropped |
| Units stored in file | Yes | No | Numbers in mm |
| Separate parts | Yes | No | Merged into one mesh |
| Usual up axis | Y | Z | Rotated (switchable) |
About DAE files
COLLADA, short for COLLAborative Design Activity, was started by Sony Computer Entertainment and handed to the Khronos Group, which published it as an open XML standard; it became ISO/PAS 17506. Files use the .dae extension. The goal was a neutral format that let different content-creation tools exchange assets without losing information, so it is broader than a mesh format: it describes geometry, materials and effects, images, cameras, lights, skeletons, skin controllers, animations and even physics. It declares its own unit with a meter attribute and an up_axis setting, which is more than OBJ or STL offer. Because it is verbose XML, files are large, and glTF has since taken over the role of Khronos's recommended runtime format. DAE still turns up in SketchUp downloads, Google Earth content, robotics (ROS) and older game and simulation assets.
About OFF files
OFF, the Object File Format, was defined for Geomview, an interactive geometry viewer developed at the Geometry Center at the University of Minnesota in the 1990s. A file is plain text. The first line holds the keyword OFF, the second gives the counts of vertices, faces and edges, then each vertex appears as three coordinates and each face as a vertex count followed by index numbers. Variants add colour (COFF), normals (NOFF) or texture coordinates (STOFF) through prefixes, and colour is optional at the end of each line. The simplicity made it a favourite in computational geometry, and benchmark sets such as ModelNet used it for machine-learning research on shape classification. CGAL and libigl read and write it directly. It has no units, materials or scene structure, so it is rarely a printing format, but converting it is common.
3D printing notes
Slicers do not open DAE, so models are converted to STL or 3MF. SketchUp users run into this often, because SketchUp exports DAE and its models are drawn in inches. Since the file records its unit scale, a correct importer gets the size right, though SketchUp-style models are also built from many separate faces and groups, with duplicated or internal geometry that can confuse slicers. Check the reported dimensions and the watertight status after conversion. MeshShift reads DAE in the browser, applies the unit and up axis from the file, and can save the result as STL, 3MF, OBJ or GLB. It does not write DAE.
Frequently asked questions
Is this DAE to OFF converter free and private?
Yes. The conversion runs in your browser with JavaScript and WebAssembly, so your DAE file is never uploaded to a server. There is no sign-up, no watermark and no daily limit; very large files are limited only by your device's memory.
What is a DAE file?
A DAE file is a COLLADA 3D scene saved as XML. It can hold meshes, materials, textures references, cameras, lights, rigs and animations. SketchUp, Blender and many older game tools export it, and Google Earth models also used it.
What is an OFF file used for?
OFF is a simple mesh format used mainly in geometry processing and machine-learning research. Datasets like ModelNet ship as OFF because the format is easy to parse. It is a plain text list of vertices and faces.
