It works automatically wherever you upload an image by wordpress, even in posts!
For check, simple replace your image extention by webp, for example you uploaded an image, the normal URI is https://…/image.png, change the “png” to webp.

For display web images in website, there is some ways:
1. Use an optimized theme that support webp
2. Use .htaccess rules (search “htaccess webp”)
3. Use modernize.js method
4. Use cache plugin that support webp, i recommend the Cache Enabler plugin.
