Google Officially adds WEBP Support for Logo Structured Data
https://developers.google.comA few days ago Google started supporting SVG as a supported image file formats for Logo structured data and now they have rolled it on to WEBP as well. Now they support all major image format jpg, png, gif, svg or webp. So if you are using WEBP logo you no longer have to pass a jpg, png or gif in the logo structured data code.
