Steps to take to save an HTML element as a PNG

Unique content: I am looking to convert a standard HTML element into an image on an HTML canvas for my website project.


I am currently working on creating a website that involves displaying various elements on the screen.

One of the key requirements is being able to capture the visual content of a specific <div> element as a PNG image file.

Although I have tried utilizing some Chrome extensions to achieve this task, unfortunately, none of them have been successful so far.


<style type="text/css">
* {
margin: 0px 0px;
padding: 0px 0px;
}
#box {
background: #FFFF00;
width: 100px;
height: 50px;
}
</style>
<div id="box">
This is my box :)
</box>

html2canvas is a useful tool that can assist you.

As stated on their official website:

This handy script enables users to capture "screenshots" of webpages or specific sections directly in the browser. The screenshot is created based on the DOM, so it may not be an exact replica of the real webpage as it doesn't take an actual screenshot but generates one using available information.

html2canvas(document.getElementById('box'), {
  onrendered: function(canvas) {
    document.body.appendChild(canvas);
  },
  width: 400,
  height: 400
});
