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
Tl;Dr: PNG but better.
No.
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?

So… detected any yet?
Yep! Here’s a few hours of combined exposure of the radiation from an americium source from a smoke detector.

Thumbs up.
I need to hear more

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.
I’m Batman.
Yes.
(Ok there might be a lossy mode but that is barely better than jpg via mozjpeg)
Still no.
Technically yes by 26%.

Smaller is not better.
26% smaller at the exact same quality is better.
Not if people can’t view or save them. PNG and JPEG are superior.
That’s a problem with adoption not the format.
Seems like a skill issue.
Size isn’t everything.
That’s what my ex used to tell me until she got cancer and passed away.
except its useless as an image
Hang all web devs
Web devs will literally look at the standards, decide to do something wrong, then blame everyone else for not agreeing with them.
