Why Convert PNG to WebP?

Smaller Files for Web

WebP produces 25-35% smaller files than PNG with lossless compression, or up to 80% smaller with lossy compression. Faster page loads, less bandwidth, better Core Web Vitals scores.

Transparency Preserved

Like PNG, WebP supports alpha transparency. Your logos, icons, and graphics with transparent backgrounds stay transparent.

Modern Browser Support

WebP is supported by all modern browsers — Chrome, Firefox, Safari, Edge, and Opera. It's the recommended image format for web use by Google.
