WebP is a modern image format developed by Google that provides superior compression compared to JPG and PNG. At equivalent visual quality, WebP images are typically 25–35% smaller than JPGs. WebP supports both lossy and lossless compression, as well as animation and alpha transparency — making it a versatile replacement for JPG, PNG, and GIF in many contexts.
WebP delivers better compression, meaning faster page loads and lower bandwidth consumption. Google's PageSpeed Insights and Lighthouse actively recommend serving images in WebP format. If you're optimizing a website, switching from JPG to WebP can significantly improve Core Web Vitals scores. All modern browsers — Chrome, Firefox, Safari, and Edge — fully support WebP.
Convertful renders your JPG image onto a Canvas element and re-encodes it in WebP format using the browser's built-in encoding capabilities. You can adjust the quality slider to balance visual fidelity against file size. The entire conversion happens in your browser — nothing is uploaded.
Completely safe. All processing is client-side. Your files never leave your device, and no data is collected or stored. Convertful's zero-upload architecture means your images remain fully private.

Yes. All modern browsers (Chrome, Firefox, Safari, Edge) support WebP. It's the recommended format for web images.
At the default quality of 90, WebP produces output that is visually indistinguishable from the JPG source while being roughly one-third smaller. Lower the slider for more aggressive compression when file size matters more than pixel-perfect fidelity.
