What is it all about?
WebP is an open format for lossless and lossy compressing images specifically for web. this format optimize the loading of images on web pages. it's developed by Google from VP8 video codec, so it is closely related to the audio compression format / WebM video.
* 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.
