What happens to PNG transparency when converting to JPEG?

PNG transparency becomes a white background when converted to JPEG, because JPEG does not support transparency. Use PNG or WebP to preserve transparency.

What are the advantages of WebP format?

WebP files are 25-35% smaller than JPEG at the same quality, much smaller than PNG, and support transparency and animation. All modern browsers support it.
