HTML and JavaScript code to desaturate or grayscale image rollovers without the need for additional image duplicates or sprites

Is there a way to achieve grayscale to color image rollover effects without duplicating images or using sprites? I'm looking for an alternative technique that can accomplish this. Any suggestions on how to implement it?

Answer №1

You can achieve this by utilizing canvas and JavaScript to convert images to grayscale. Check out the interactive code demonstration below:
