What is PNG?
PNG is a lossless format that keeps sharp edges and supports transparent backgrounds. It is best for logos, screenshots, graphics with text and images that need transparency.
What is WebP?
WebP is a modern web format that is usually 25–35% smaller than JPG or PNG at similar quality. It is best for websites, where smaller images load faster.
