Hi @sfuma
Thank you for suggesting a new feature for one of our plugins! You are actually not the first to have requested this feature! That means a feature request is already created and is currently under review?by our product team.
What’s next?
Our product team will assess feature requests in relation to other open bug reports and new features. Based on their assessment, the feature request will be given a priority level. Our developers work on the highest priority first. Unfortunately, this means we cannot give you an estimate if or when they’ll start working on your request.
If you have any further information that may affect the prioritization, please feel invited to reply to this email.
For now, you can only use the file types of JPEG, PNG, and GIF to set as the og:image tag for the Facebook or Twitter image in the social tab of the Yoast SEO meta box. WEBP isn’t supported at this time, but please do check our changelog and release posts from time to time for upcoming features and additions to the Yoast SEO plugin.
Thanks!
