You'll get an image encode with base64 string from Plotly.toImage(), and you can convert base64 string to image in many ways. (For example like this page.)

Assume the HTML code is like this:

<div id="chart">
  <!-- chart here -->
</div>

Then the JavaScript code should be like this:

Plotly.toImage('chart', { format: 'png', width: 800, height: 600 }).then(
    function (dataUrl) {
    // use the dataUrl
})
