Why WebP is Better for Web Performance
WebP typically produces files 25-35% smaller than equivalent JPG images at the same visual quality. For websites, this means faster page loads, lower bandwidth costs, and better Core Web Vitals scores.
Google developed WebP specifically for web use. All modern browsers now support it, making it a practical choice for new websites and image optimization projects.
Real-World File Size Savings
A typical 500KB JPG might become 350KB as WebP with identical visual quality. For image-heavy sites serving thousands of images daily, these savings accumulate to significant bandwidth reductions.
The compression efficiency comes from WebP's modern encoding algorithms. It can achieve similar visual results with less data than the older JPEG standard developed in 1992.
Browser Compatibility Today
Chrome, Firefox, Edge, Safari, and most mobile browsers support WebP. Internet Explorer does not, but its usage has dropped below 1% globally. For remaining legacy browsers, serve JPG as a fallback using the picture element.
If your audience skews toward modern browsers, WebP is a safe choice. Check your analytics to confirm browser distribution before deciding.
Convert Images Locally
FormatWiz encodes your images as WebP entirely in your browser. The conversion uses canvas APIs to decode the JPG and re-encode it in WebP format. Your images stay on your device throughout.
Batch convert multiple images without worrying about upload limits or server-side processing delays.
