Hi all.

I found this good article on how to automatically serve webp images with imageprocessor https://kieron.codes/blog/using-webp-images-in-umbraco/ but half of my images is now triple size and half is about half size of the original.

I then found an article on https://help.shortpixel.com/article/102-why-the-resulting-webp-images-are-bigger-than-the-original-png-files

"The WebP compression algorithm was created, according to Google, as an alternative for both PNG and JPEG files. While generally the resulting WebP image is, on average, 26% smaller than the original PNG and 25-34% smaller than the original JPEG, sometimes the resulting image can be bigger. Much bigger. We encountered cases when the WebP version of a PNG was double or three times the size of the original file size.

There is nothing to worry about: it is just a limitation of the WebP algorithm sometimes, especially when the original file is already optimized. Google explains it on this section of the previous page: Can a WebP image grow larger than its source image?"

Now does anyone have some experience or best practice with this, they would like to share?

I was thinking if there was a way of telling when to use webp and when not to use it automatically..
