Everything About WebP Format
WebP is a modern image format that combines the best qualities of JPG, PNG, and GIF in one format.
What is WebP?
WebP (pronounced "weppy") is an image format developed by Google and introduced in 2010. It was created to replace existing web image formats, providing better compression and smaller file sizes while maintaining high quality.
The format is based on VP8 video compression technology (for lossy compression) and uses its own algorithm for lossless compression. WebP supports transparency (alpha channel) and animation, making it a universal solution for various types of images.
