Why you should convert your pictures to WebP

If your site still ships images as JPG or PNG, you are leaving an enormous performance win on the table. Modern browsers have supported the WebP format for years, and switching your images over is one of the highest-leverage optimizations available.

What WebP gets you

• 25–35% smaller files than JPG at equivalent visual quality
• Up to 50% smaller than PNG while keeping alpha transparency
• Both lossy and lossless modes in a single format
• Animation support as a lighter alternative to GIF

Practical impact

Every kilobyte removed from your largest image directly improves your Largest Contentful Paint. Faster LCP means better Core Web Vitals, which Google uses as a ranking factor.

How to get started

Drop your existing photos into PictoWebP and download the WebP output. The whole process takes seconds, runs entirely in your browser, and never uploads your files anywhere.
