WebP file format
WebP (.webp): images on websites, where smaller files mean faster pages.
WebP was created by Google to make web pages load faster. Lossy WebP is typically 25–35% smaller than a JPG of similar quality, and lossless WebP is about a quarter smaller than PNG. It also supports transparency and animation. Many websites now serve WebP automatically, which is why images you download often end up as .webp files that older software refuses to open.
