WebP Converter
Convert images to the modern WebP format for better web performance.
What is WebP?
WebP is a modern image format from Google that delivers lossy and lossless compression while supporting transparency and animation. Smaller file sizes mean faster page loads and leaner downloads without giving up visual quality.
Benefits of WebP format
- Typical size reductions of 20–70% compared to JPEG or PNG at similar quality.
- Better Core Web Vitals from faster image delivery and fewer bytes over the network.
- Supports transparency and animation in a single format, simplifying asset pipelines.
- Browser-side conversion keeps your images local—no uploads or external services.
Drop in one or many images. Conversion runs entirely in your browser and never leaves this page.

About WebP Image Converter
The WebP Converter transforms standard images (JPG, PNG) into the highly efficient WebP format. This image converter allows you to optimize images for the web, significantly reducing file sizes while maintaining visual fidelity.
Improve your Core Web Vitals and page load speeds. WebP files are often 30% smaller than their JPEG counterparts. Using this tool for batch conversion helps you modernize your asset library quickly without needing server-side processing.
Upload one or many images. Adjust the WebP quality slider to find the balance between size and sharpness. Download the converted files individually or as a group.
Under the Hood
Conversion is handled client-side using the HTML5 `<canvas>` API. Images are drawn to an off-screen canvas and then exported using `canvas.toBlob(callback, "image/webp", quality)`. This leverages the browser's internal graphics engine for high-performance encoding. No image data is ever uploaded to a server, ensuring privacy and speed for large assets.
