What are PNG and WEBP files?

PNG (Portable Network Graphics) is a lossless format built for quality and transparency. Every pixel is stored exactly — nothing is discarded — which makes PNG ideal for logos, icons, UI graphics, and screenshots where sharpness matters. The downside is file size: PNG images are large, which directly affects how fast your web pages load. A logo at 500 KB as PNG might only be 50 KB as WEBP with no visible difference.

WEBP is Google's modern image format, released in 2010 specifically to improve web performance. It achieves 25–35% smaller file sizes than PNG at equivalent visual quality, and like PNG it fully supports alpha transparency. All modern browsers — Chrome, Firefox, Safari 14+, and Edge — render WEBP natively. For web developers and designers, converting PNG assets to WEBP is one of the easiest wins for page speed and Core Web Vitals scores.

Convert PNG to WEBP when optimising images for a website, reducing bandwidth costs, improving Lighthouse or PageSpeed scores, or serving images through a modern CDN. The transparent background in logos and icons is fully preserved in WEBP, making it a direct drop-in replacement for PNG in any modern browser context.
