Whether you just want to add the script to your page or use a bundler, we have you covered.

<script src="https://unpkg.com/markerjs"></script>Run this command from your console:
npm install markerjsDownload .zip or .tar.gz from our release page on GutHub.
Want to change something in the source code? Clone the repository:
git clone https://github.com/ailon/markerjs.git
var mark = new markerjs.MarkerArea(document.getElementById('myImage'));
mark.show(function(dataUrl) {
var res = document.getElementById("resultImage");
res.src = dataUrl;
});
import { MarkerArea } from 'markerjs';
const mark = new MarkerArea(document.getElementById('myImage'));
mark.show((dataUrl) => {
const res = document.getElementById("resultImage");
res.src = dataUrl;
});
Did we mention you can just click the image above and annotate it?
Click the image above to try a custom UI marker.js implementation
You don't have to use marker.js with its built-in toolbar. It's perfectly understandable that often you'd rather integrate annotation functionality into your own UI. And you may also want to limit available marker types according to your requirements.
marker.js has you covered. Instead of calling MarkerArea.show() like described above, call MarkerArea.open(),
then call one of the API methods from your UI to perform whatever action you are after.
Refer to documentation for a reference and an example, and try the demo to the left.
You are welcome to use marker.js absolutely free in any type of project (free or commercial) under our Linkware license.
The only limitation of the Linkware license is that you cannot remove a small logo/link back to this site in the corner displayed while the user is annotating (it is not rendered in the final image). If this doesn't work for you, you are welcome to purchase one of our commercial licenses below.
