Just get the premium version

I have used a lot of methods to convert to WebP, and this is by far the easiest. This tool (paid version) allows me to set a max width OR height, which is excellent for handling landscape and portrait images in the same batch. Then, there's the auto-start feature which makes moving through the process a breeze, when paired with "save in original image folder". I just drop groups of files in to be optimized and its off to the races. Very quick conversion, and I have also found the compressed image sizes to be smaller than several other tools I have used like Squoosh or WebPShop (Photoshop).
