✦ tip from dragontail
Google officially recommends WebP for web images, and Dragontail's own site uses WebP for all image assets. When I switched our blog images from JPG to WebP, page weight dropped by 28% and LCP improved noticeably. If you're building for the web in 2026, WebP should be your default image format.
