WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters, and web developers can create smaller, richer images that make the web faster.
WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index.
The Microsoft Edge Betar supports WebP
Apple Safari is the latest major browser that lacks WebP support.
85% to 95% of desktop browsers now support WebP
For mobile and tablets, the figures are somewhat lower.
If Apple supports WebP in future versions, more than 90% of browsers will support WebP on all platforms.
Thanks for adding this request. I think the links triggered our spam filter. I'm actually out on vacation* right now, so it may take a bit to get back to everyone, but I'll be back on Tuesday.
*By "vacation" I mean I'm preparing to defend my dissertation.
