Why Webmasters and Developers Are Switching to WEBP Images

Developed by Google, WEBP is a modern next-generation digital image format built specifically to accelerate web page loading speeds. Compared to legacy JPEG and PNG formats, WEBP offers superior lossy and lossless compression algorithms, reducing image file sizes by 25% to 35% without visible quality loss.
