Difference Between WebGL and Canvas
WebGL is the version of OpenGL, which is a 3D engine. It helps its user to perform 3D manipulation in the web browsers. Canvas being a part of HTML5 allows its users with dynamic, script rendered 2D shapes. It can be considered a low level that has the ability to update bitmap images and does not have a built-in scene graph. These are used in the games (2D and 3D) with abstraction layers such as PIXI.js and several others like Three.JS and Unity.

Below is the top 7 difference between WebGL vs Canvas:
Key Differences between WebGL and Canvas
Both are popular choices in the market; let us discuss some of the major difference :
- The canvas element is the HTML element and was introduced with its 5th generation (HTML5). This allows its users to draw on the screen using JavaScript, because of this a dynamically generated graphics and animations are possible on the client side whereas WebGL is non-standardised API that allows OpenGL functionality using JavaScript. A 3D rendered using a browser is possible.
- Since both Canvas vs WebGL are JavaScript API’s so there will be similarities to some extent, especially if we talk about bindings and framework development. Libraries are there in both that can save the development team’s precious timings, and organizing and preferring codes. So, the point of discussion here is code writing. Canvas API is much easier to learn and understand if a user is looking to understand and write code from the initial level (or beginning). One can say minimal math understanding is required for understanding canvas whereas WebGL needs a person who has some strong mathematical understandings.
- WebGL vs Canvas are HTML5 goodies. If a device supports one than it will automatically support other. The native 3D API for WebGL is faster and has more capabilities like rendering pipelines, code accessibility, and faster execution.
- Games are there everywhere. One can go to PLAYSTORE to look for any number of possibilities and categories. Talking of 2D gaming and how these score upon each other in terms of 2D gaming. Canvas for sure if your requirement id 2D gaming (advanced). Amazing drawing features for 2D using canvas. The nature of your game makes this kind of selection. If your requirement is a 2D gaming which has few moving items than Canvas is the solutions and if there are repeatedly new frames than for such kind of rendered loop one needs to prefer Webgl.
WebGL vs Canvas Comparison Table
Let’s look at the top Comparison between WebGL vs Canvas –
|
Canvas |
WebGL |
| Introduced by Apple for their use inside and for their MAC OS. | Mozilla Foundations are the Original Authors for WebGL components. Though the developers are Kronos WebGL working group. |
| This came into existence in the year 2004. | In the year 2011. |
| This is the predecessor of WebGL. | WebGL evolved out of the Canvas 3D experiments. |

Browsers support:
Desktop Browsers: Chrome, Mozilla, Safari, Opera, IE, Edge, Vivaldi Mobile browsers: BlackBerry 10, Playbox, IE, Firefox mobile, Firefox OS, Chrome, Maemo, Meego, MS Edge, Opera Mobile, Ubuntu, WebOS, iOS |
| A lesser Market value in terms of purchasing the license. | More compared to canvas. |
| Talking of speed factor, Canvas slows down to its components. | WebGL is greater than Canvas in terms of speed. |
| Generally preferred for 2D rendering and works related. | More preferred for 3d though can also work on 2D. |
Conclusion
Here we can see that the conclusion is easier and clear. One is easy to work and has an easier learning curve while other is hard to execute and has a great impact on the gaming industry. Canvas which is good to work when the requirement of the application is light and 2D oriented. WebGL when the work you are developing is going to be more complex with more frames rate and most importantly its 3D. Each has there pros and cons and the work of the users depends upon these when it’s time to choose the right match for your work. Both Canvas vs WebGL have great Libraries and User base.
