WebP is the format the modern web is built for: it produces files 25–35% smaller than JPEG and far smaller than PNG at the same visual quality, while still supporting transparency. Since images are usually the heaviest thing on a page, switching them to WebP is one of the single most effective ways to speed up load times — which directly improves Core Web Vitals and, in turn, your search ranking. This converter turns JPG, PNG, GIF, or BMP files into WebP right in your browser, with a quality slider so you control the size-versus-sharpness balance and batch support for multiple files. Nothing is uploaded — the Canvas API does the work on your device — and transparency from PNGs is preserved in the WebP output. WebP is supported by every modern browser, so for almost any website it is a safe, high-impact upgrade.
