Only convert images

Hi,

How should i set the settings of your plugin if i only need to convert the images (existing and new ones) to webp but not to serve them somehow on the website (because i use nginx directives on Plesk to do the serving). First of all what Operation mode ? (i use Cloudflare so should i use the CND friendly or it doesn’t matter because it is only the image conversion?). And i guess except the “Convert on upload?” the rest settings should be off right?

regards
