Only IE11 (&lt;0.5% of traffic) and very old mobile browsers don&#8217;t support WebP.

Long-term AVIF may succeed WebP, but WebP has years of adoption lead and remains the practical choice for 2025.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does WebP support camera metadata (EXIF)?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes \u2014 WebP supports EXIF, XMP, and ICC color profile metadata.
