Why is it necessary to convert image formats? Compare PNG, JPG, WebP

Each image format has its own advantages suitable for different uses. WebP is Google's new format, 25-34% smaller than JPG and 26% PNG with equivalent quality, supporting both lossy, lossless and transparency - ideal for websites because it reduces page load time and saves bandwidth. JPG (JPEG) is the most popular format for photos, effective lossy compression for images with many colors and gradients, supported by all software and devices. PNG supports transparency, lossless compression without losing quality, suitable for logos, icons, and images with sharp text. You need to convert to WebP when optimizing images for your website to improve Core Web Vitals and SEO. Convert to JPG when you need to share photos via email or social networks. Convert to PNG when transparency or absolute quality is needed.
