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).

It just works. Only app I've found that does what it says it will.

This little app is just perfect. It does everything it says it will, it's cheap, and it's efficient. I wish more companies wrote software like this today. Kudos to the devs for a great piece of functional software, with a good UI, and excellent price!
