I have the same issue since a while!
Hello @sakti26 and @rl_stine,
Thanks for reaching out regarding your image format.
Indeed, WordPress 5.8 now includes support for webp images. For now, it’s still not supported by the Yoast SEO plugin. 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 to add the webp image format for open graph image tags.
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 or if or when they’ll start working on your request.
We are going ahead and marking this issue as resolved due to inactivity. If you require any further assistance please create a new issue.
