caniuse.com/webp but need to update image output like this

Code:

<picture> <source srcset="img/awesomeWebPImage.webp" type="image/webp"> <source srcset="img/creakyOldJPEG.jpg" type="image/jpeg"> <img src="img/creakyOldJPEG.jpg" alt="Alt Text!"> </picture>

we will study if we can add it in core

Ok, Georgios says that we can convert all images on server and then just replace file extensions in DB (find/replace).
But also we need to increase number before file name if the old extension had fewer characters.



So, first step in to convert images on server.
And second is to find and replace png to webp.
