I've a WP website and all of my pages are in .png format. Is there an easy method to convert them? Or do I have to realize it manually?

One way is to use an online converter. Many online converters are available, and most are free to use. Simply upload your image to the converter, which will be converted to webp format in seconds. This is one of my absolute favorites: https://cloudconvert.com/
