Hi @jiyeoung
By default, Optimole serves images in WebP/AVIF format for every visitor that supports this format. You don’t need to do anything to activate this, all is done by our service automatically when someone who is using a WebP/AVIF compatible browser is checking your site.
However, due to the fact that we don’t change the image extension of the resulting image, you might see that the image is still using the jpg/png extension when they are delivered.
You don’t need to worry about this as even if they have the jpg/png extension, they will still be served using the proper format.
Thanks and have a great day!
