Depending on the content of the image, the compression ratio can vary a lot. The 26% figure is probably for "normal" photos. My images are mostly a few shades of black with a few white pixels (using a camera as a radiation detector) and I guess WebP is way better at compressing that than PNG.

Yep! Here's a few hours of combined exposure of the radiation from an americium source from a smoke detector.

If you'd upload this image with no description I'd be sure it's a photo of stars in the sky lol
