image/webp
The MIME type for WebP — Google's web-optimised image format, producing smaller files than JPEG or PNG at equivalent quality.
Typical extensions
Primary uses
- Shrinking image payloads on the web
- Progressive enhancement via `<picture>` with a JPEG fallback
- CDN image optimisation pipelines
In a browser
Chrome, Edge, Firefox, and Safari 16+ support WebP natively. Provide a JPEG fallback in `<picture>` for older Safari.
On a server
Content negotiation via the `Accept` header is standard: serve WebP only when the client advertises `image/webp`.
In email
Apple Mail, Outlook 2019+, and Gmail handle WebP, but older clients will break. Stick to JPEG or PNG in email when possible.
