About PNG to WebP

Convert PNG graphics, screenshots and logos to WebP to make them far lighter for your website while keeping transparency. WebP supports both lossy and high-quality compression with an alpha channel, so a transparent PNG becomes a transparent WebP that loads faster. Everything is processed in your browser.
