File extensions: .webp

Modern raster format — smaller than JPEG and PNG with transparency.

What is image/webp?

image/webp is Google's modern replacement for JPEG and PNG. It offers ~30% smaller files at similar quality for photos, supports transparency and animation, and is now available in every major browser.

Typical usage

Any image on the modern web — photos, graphics, animated stickers.

Common gotchas

For maximum browser support, serve WebP alongside a JPEG/PNG fallback via <picture> element and Accept negotiation.
