Three.js can use WebGL to render your scenes on all modern browsers. For older browsers, especially Internet Explorer 10 and below, you may have to fallback to one of the other [link:https://github.com/mrdoob/three.js/tree/master/examples/js/renderers renderers] (CSS2DRenderer, CSS3DRenderer, SVGRenderer). Additionally, you may have to include some polyfills, especially if you are using files from the [link:https://github.com/mrdoob/three.js/tree/master/examples /examples] folder.

Note: if you don't need to support these old browsers, then it is not recommended to use the other renderers as they are slower and support less features than the WebGLRenderer.

Google Chrome 9+, Firefox 4+, Opera 15+, Safari 5.1+, Internet Explorer 11 and Microsoft Edge. You can find which browsers support WebGL at [link:https://caniuse.com/#feat=webgl Can I use WebGL].

Here are some features used in three.js. Some of them may require additional polyfills.

Feature	Use Scope	Modules
Typed Arrays	Source	BufferAttribute, BufferGeometry, etc.
Web Audio API	Source	Audio, AudioContext, AudioListener, etc.
WebVR API	Source	WebVRManager, etc.
Blob	Source	FileLoader, etc.
Promise	Examples	GLTFLoader, GLTFExporter, WebVR, VREffect, etc.
Fetch	Examples	ImageBitmapLoader, etc.
File API	Examples	GLTFExporter, etc.
URL API	Examples	GLTFLoader, etc.
Pointer Lock API	Examples	PointerLockControls

Just import polyfills based on your requirements. Taking IE9 as an example, you need to polyfill at least these features:

• Typed Arrays
• Blob
