Technology proposal: WebP

- on 9 February 2013, 5 years ago

Homepage: https://developers.google.com/speed/webp/

WebP is a new image format that provides lossless and lossy compression for images on the web. WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller in size compared to JPEG images at equivalent SSIM index. WebP supports lossless transparency (also known as alpha channel) with just 22% additional bytes. Transparency is also supported with lossy compression and typically provides 3x smaller file sizes compared to PNG when lossy compression is acceptable for the red/green/blue color channels.

Thank you for that proposal. That would indeed be interesting to see the usage rate of that format.

We have added WebP to our image format surveys.
