This conversation has been merged. Please reference the main conversation: Lightroom: Support for WebP
By the end of the year every major web browser will be supporting (or have plans for supporting) the WebP format. The format is completely open source, so I am not sure why Photoshop is so far behind the curve on this. Please add native support in Photoshop. The plugin is a crude work-around for what should be built-in to PS.
