Why convert PNG to WebP?
PNG is a lossless image format: every pixel is stored exactly, and it supports full transparency. It is the standard for screenshots, logos, icons and graphics with text.
WebP is Google's modern web format. At the same quality it is usually 25-35% smaller than JPG or PNG, and it supports transparency and animation.
Choose WebP when the image is going on a website and should load fast.
