This has the unfortunate side effect of not yet being fully supported in Safari: https://caniuse.com/webp

Well, you could always add some fallback:

<picture>
  <source srcset="rambo.webp" type="image/webp">
  <source srcset="rambo.png" type="image/png">
  <img src="rambo.png" alt="Hero image">
</picture>

Yep you'd have to

@jrgp @XvayS @Appnautic you dont need to convert images to webp, its handled by gatsby image plugin, if its supported it becomes webp if not there is a fallback for that case to serve standard format like jpg/png
