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.
I wanted to see if I could detect the radiation from a small sample of americium-241 that I pulled out of a smoke detector, so I put a Pi camera with no lens facing it and took exposures for a couple hours. After combining them and removing dead pixels I ended up with tons of tiny white specks where radiation had hit the camera sensor. I linked the final image below, and here’s a timelapse video (compositing newer frames onto older frames to keep the radiation specks). video
Might want to check your math.
What do you mean? That’s the total file size of the images before and after I converted them to webp.
How is that possible when google says it is 26% smaller?

So… detected any yet?
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
Ooh neat!!
I need to hear more

Thumbs up.
What? Why? I see one number, I see another number, I report both numbers and because it’s not what you’re expecting, then “it must be my math skills”?
How does that make sense in any context?
Who are you? I didn’t tell you anything.
