Is there any way I can open a .webp file in Corel X7 Photo-Paint?

I have recently learned that there is a new image format created by Google that is being used:

Some of the pictures I edit are now being saved in this format.  Is there anyway that I can open a .webp image in Corel X7 Photo-Paint, or will I have to find a way to convert the image first?

If converting the image first (such as to a .jpg) is my only option, then can someone suggest a way I can do this for free?  (I do not want to subscribe to a web site/service for doing this).

Thank you.
