JPEG XL images aren’t currently supported in Google Images or as previews in Discover, Google Search Advocate John Mueller said on Bluesky .

His post came as browsers added the format. JPEG XL support arrived in Chrome 155 , which Google began rolling out widely on Oct. 6 after early releases to a small percentage of users starting Sept. 23. Firefox followed with Firefox 158 on Oct. 13.

In a reply, Mueller explained that serving JPEG XL through a picture element should work with any search engine, since the element includes a regular img element.
