Should I convert all my JPEG images to WebP?

Is WebP supported in all browsers?

WebP is supported in Chrome, Firefox, Safari (14+), Edge, and Opera — covering over 95% of web users. For legacy Safari support (pre-2020), provide a JPEG fallback using the HTML element.

Does WebP look better than JPEG?

At the same file size, WebP typically looks better than JPEG. At the same visual quality, WebP is significantly smaller. In practical terms, WebP delivers better quality per byte.

Can I use WebP for emails?

No — Outlook (which accounts for 30%+ of business email clients) does not support WebP. For email, use JPEG for photos and PNG for graphics. WebP is only recommended for web and app delivery.
