Hello everyone 👋

A few months back, I was working on a web-based project where a feature was required that is to take a screenshot of an HTML div in the browser and show it to the user. I was like, sorry this is not possible. Then I did some research and got to know about this library called html2canvas.

So in this article, I will show how can we capture a screenshot of a web page or any element of it using html2canvas.



Include the html2canvas.min.js file in your HTML file.

<script src="./html2canvas.min.js" defer></script>

Now we will use the html2canvas method to capture the screenshot of our web page or the HTML element.

html2canvas(document.getElementById("main"), {
  allowTaint: true,
  useCORS: true,
.then(function (canvas) {
  // It will return a canvas element
  let image = canvas.toDataURL("image/png", 0.5);
.catch((e) => {
  // Handle errors

The html2canvas method takes two arguments

  • first is the HTML element whose screenshot you want.
  • second is a configuration object.

In the configuration object, we are using

  • allowTaint to allow cross-origin images to taint the canvas.
  • useCORS to attempt to load images from a server using CORS.

You can find the available configuration options here.

Then we are converting the returned canvas into a base64 image URL using the toDataUrl method which expects two arguments

  • type : image format.
  • encodingOptions : number between 0 and 1 indicating the image quality.

And that's it, we captured the screenshot of our HTML element.


This library has some issues, some of them are mentioned in the docs. I recommend going through it and understand it before using it in any production-based environment.

If you are aware of other ways to achieve a similar kind of result, please feel free to share.
