It losslessly compressed ~150GB of my PNGs to ~75GB, so I'd say it's definitely better space-wise.
It's absolutely not loseless at any kind of quality past web content
The WebP format supports fully lossless compression in addition to lossy compression. I used the lossless mode for my images.
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?
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.
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!!
Thumbs up.
I need to hear more
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
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.
