Why Image Optimization Matters

Images often account for more than 50% of a webpage's total weight. Unoptimized images can kill your load times, hurt your SEO rankings, and frustrate your users.

The Power of WebP

WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster.

  • Lossless images are 26% smaller compared to PNGs.
  • Lossy images are 25-34% smaller than comparable JPEG images.

How to Convert

Using our Image Converter, you can easily transform your existing PNG and JPG library into WebP. The tool runs locally, so you can batch process your assets without worrying about privacy or bandwidth caps.

Best Practices

  1. Resize first: Don't use a 4000px wide image for a thumbnail.
  2. Choose the right format: Use WebP for photos and SVG for logos.
  3. Use lazy loading: Let the browser load images only when they enter the viewport.
