File Extension Guide📖 What is a DAE File?
A DAE file is a 3D model saved in the COLLADA format, used to move 3D content between different graphics programs. The name stands for Digital Asset Exchange, and it uses the .dae extension. Inside, a DAE file stores the shapes, surfaces, animation and even physics of a 3D scene as plain XML text, which is why it works across so many tools rather than being tied to one.
COLLADA stands for Collaborative Design Activity. It was created by Sony and is now maintained by the Khronos Group, and it was adopted as an open standard so that 3D applications could share files without locking anyone into a single program. That interchange role is the whole point of the format. A model built in one tool can be exported as a DAE and opened in another. It is also the format Google Earth uses for 3D buildings, where the DAE sits inside a KMZ file, which is why many people first meet the extension there.
Because a DAE stores everything as readable XML, the files are larger and slower to load than binary 3D formats. That openness was its strength for years, and it is still a common export option, though newer formats such as glTF have taken over for web and real-time use.

📦 What is Inside a DAE File?
A DAE file describes a whole 3D scene, not just a single shape. It records each part as XML so any COLLADA-aware program can rebuild the scene. This diagram shows what it can hold.
Because everything is XML text, you can open a DAE in a text editor and read the tags, which is useful for checking a file. Editing it by hand is impractical though, since a real model holds thousands of coordinates. A 3D program is the right tool for that.
💻 How to Open a DAE File
A DAE is a 3D model, so an image viewer cannot show it as a picture. You open it in 3D software, which rebuilds the scene and lets you rotate, inspect and edit it. Many free tools handle DAE, so you do not need an expensive program.
Free 3D tools
Blender opens DAE files and is free and cross-platform, making it the usual choice for viewing and editing one. SketchUp imports COLLADA too, and on a Mac the built-in Preview can display a DAE without any extra software. The quickest option with nothing to install is a free online DAE viewer, which opens the model straight in a browser on any device, letting you rotate and inspect it. If the model has separate texture files, upload those alongside the DAE so the surfaces show correctly.
Professional software
Autodesk Maya and 3ds Max open DAE files, as does Cinema 4D, and Adobe Photoshop can import one as a 3D layer. Game engines like Unity and Unreal also read COLLADA when importing assets. To import, use the program's Import or Open command and pick the .dae file.
🔄 How to Convert a DAE File
People convert a DAE because the format they need is different. The target depends on where the model is going, and the steps are the same in any 3D tool. Univik's File Converter can perform the export. To preview a DAE without a 3D editor, you can preview one with Univik's File Viewer straight in a browser tab.
Open the DAE
Import the file into a 3D program such as Blender, or load it into an online 3D converter. The tool reads the COLLADA data and shows the model.
Pick the target format
Choose the format for your goal. Use glTF or GLB for the web and AR, FBX for the Unity or Unreal game engines, and OBJ or STL for general sharing or 3D printing.
Export it
Choose Export, select the format and save. Check the result, since materials or animation can shift between formats, and the geometry usually carries over cleanly.
Converting to glTF is often worth doing for an old DAE, because the newer format is smaller, loads faster and is supported natively on the web. Keep the original DAE as well, in case you need to go back to it.
⚔️ DAE vs glTF
Both DAE and glTF come from the Khronos Group and both are open, so they are often compared. glTF is the newer format and has taken over most of the roles DAE once filled.
| Aspect | DAE (COLLADA) | glTF |
|---|---|---|
| Storage | XML text, verbose | Compact JSON, plus a binary GLB option |
| File size | Larger | Smaller for the same model |
| Web support | Not read by browsers directly | Built for the web and AR |
| Best for | Interchange between design tools, older workflows | Web, real-time apps and modern pipelines |
glTF is sometimes called the JPEG of 3D because it is compact and ready to display. DAE still appears as an export option in many design tools and in older asset libraries, so both remain in use, with glTF the default for anything new and web-facing.
🆚 DAE vs OBJ and FBX
DAE, OBJ and FBX are all common 3D interchange formats, and choosing between them comes down to what a model needs to carry.
DAE
Open XML format that carries geometry, materials, animation, cameras and lights. Flexible but verbose, so files are large.
OBJ
A simple, widely supported format for static geometry and basic materials. It has no animation, which keeps it light and easy to share.
FBX
An Autodesk format popular in games and film for rich scenes with animation. It is proprietary, unlike the open DAE and OBJ.
In short, pick OBJ for a plain static shape, FBX for animated scenes inside Autodesk and game tools, and DAE when you want an open format that still carries animation. For the web, convert any of them to glTF.
🔀 Related 3D Model Formats
DAE sits among several 3D formats you may meet, each suited to a different job. They all describe 3D models under their own extensions.
.gltf / .glb | The modern Khronos format for the web and AR. GLB is the single-file binary version, and it is the usual successor to DAE. |
.obj | A simple, universal format for static geometry, widely supported across almost every 3D tool. |
.fbx | An Autodesk format for rich animated scenes, common in game engines and film production. |
.stl | A geometry-only format that 3D printing uses, describing just the surface of a model. |
.usdz | Apple's format for AR on iPhone and iPad, used for previewing 3D models in a real space. |
❓ Frequently Asked Questions
Open it in 3D software, since a DAE is a 3D model rather than an image. Blender is free, cross-platform and opens DAE files, and SketchUp imports them too. On a Mac, the built-in Preview can display a DAE. Several free online 3D viewers also open one directly in a browser. Use the program's Import or Open command and select the .dae file.
DAE stands for Digital Asset Exchange. It is the extension for the COLLADA format, which stands for Collaborative Design Activity. The name reflects its purpose, which is to exchange 3D assets between different graphics programs using a shared open standard.
Open the DAE in a 3D tool such as Blender or an online 3D converter, then export it in the format you need. Choose glTF or GLB for the web and AR, FBX for game engines, and OBJ or STL for general use and 3D printing. Check the result afterwards, because materials and animation can change between formats even though geometry usually transfers cleanly.
COLLADA support varies between programs, so a DAE that looks right in one tool can lose materials, textures or animation in another. If it will not open, try a different 3D program such as Blender, which has broad support. If it opens but looks wrong, the missing parts are usually textures that live in separate files, so keep those alongside the DAE, or convert the model to glTF, which bundles everything together.
Both are open Khronos Group formats, but glTF is newer and more efficient. DAE stores data as verbose XML, so files are large and browsers cannot read them directly. glTF uses compact JSON, with a single-file binary version called GLB, and it is built for the web and AR. glTF has largely replaced DAE for modern and online work, while DAE remains a common export option in design tools.
Yes. Besides Blender, which is free, a Mac can open a DAE in the built-in Preview, and several free online 3D viewers display one in a browser with nothing to install. SketchUp's free web version also imports COLLADA. You do not need expensive software to view a DAE, only to do advanced editing.
Not directly. 3D printing software expects an STL or similar geometry format, and most slicers do not accept a DAE. Open the DAE in a 3D tool such as Blender, then export it as STL. That gives the slicer the surface geometry it needs, since a DAE also carries materials and animation that a printer does not use.
It depends on the job. DAE is still useful when a program requires it, in open-source workflows, or for legacy assets, and it remains a common export option. For anything new and web-facing, glTF is the better choice because it is smaller and better supported. Many people keep a DAE for interchange and convert to glTF when it is time to publish.
Use a free online DAE viewer. Several websites let you drag a .dae file into the page and see the model render in your browser, where you can rotate, zoom and inspect it, with nothing to install and on any device. If the model uses separate texture files, upload those alongside the DAE, or put everything in a ZIP first, so the surfaces appear correctly.
Google Earth uses COLLADA for its 3D building models, and it packages them in a KMZ file. A KMZ is a ZIP archive, so if you rename it to .zip and extract it, you find the .dae model and its textures inside. You can then open that DAE in a 3D tool such as Blender, or in an online viewer, the same as any other COLLADA file.
📝 Summary
A DAE file is a 3D model in the COLLADA format, saved with the .dae extension and written as XML so it can move between graphics programs. Digital Asset Exchange was created by Sony, is maintained by the Khronos Group as the ISO/PAS 17506 standard, and stores geometry, materials, animation, cameras and lights. Open one in a 3D tool such as the free Blender or SketchUp, and convert it to OBJ, FBX or glTF when a different format is needed. The newer glTF has largely replaced DAE for web and real-time use, though DAE stays common for interchange and older projects.
