How to Convert Image Formats Online
Modern web browsers support multiple image formats, each designed for different use cases. Converting between them requires a rendering engine that can decode the source pixel data and re-encode it using a different algorithm. Our tool uses the browser's native HTML5 Canvas API to do this in milliseconds directly on your machine.
The process is straightforward: the source image is decoded and painted onto an invisible memory canvas. Then the canvas's raw pixel data is re-encoded into the target format using the browser's built-in codec and exported as a downloadable file.

Why WebP is the Future of Web Performance
Developed by Google and now natively supported by all major browsers (Chrome, Safari, Firefox, Edge), WebP delivers dramatically better compression than both JPG and PNG. A typical WebP image is 25–35% smaller than a comparable JPG at the same visual quality.
Google's own Core Web Vitals scoring system actively rewards websites that use modern formats like WebP, directly boosting SEO rankings. If your website is still serving JPG images, converting them to WebP is one of the single highest-impact performance optimizations you can make. Our converter makes this migration effortlessly fast.
