I am trying to implement google feed in xml format based https://support.google.com/merchants/answer/7052112?hl=en#zippy=%2Cother-requirements-to-keep-in-mind. In docs it stated that image_link attribute have following supported file formatsGIF (.gif), JPEG (.jpg/.jpeg), PNG (.png), BMP (.bmp), and TIFF (.tif/.tiff) and the image’s file extension should correspond to its format. Thus i have a question does this attribute will accept Google’s WEBP image format or not?
No, WEBP is not supported as of writing.
