WebP Converter — Convert Images To and From WebP Free

This bidirectional image converter handles both directions of WebP conversion: transforming WebP images into JPG or PNG format, and converting JPG or PNG images into the WebP format. WebP is a modern image format developed by Google that provides superior compression ratios compared to JPEG and PNG, often reducing file sizes by 25-35% while maintaining equivalent visual quality through both lossy and lossless compression modes.

The conversion leverages the HTML5 Canvas API as its rendering pipeline. For WebP-to-JPG/PNG conversion, the tool loads the WebP image onto a canvas element using the browser's native WebP decoder, then exports the canvas content using toBlob() with the target MIME type (image/jpeg or image/png). For JPG/PNG-to-WebP conversion, the same canvas pipeline operates in reverse, accepting standard image formats and exporting with the image/webp MIME type at a user-configurable quality level ranging from 0.1 to 1.0.

An adjustable quality slider gives users precise control over the compression-to-quality tradeoff, with real-time file size estimates updating as the slider moves. The converter displays before-and-after previews showing the original alongside the converted result, with file size comparisons highlighting the compression savings. All processing happens client-side ensuring complete privacy for sensitive images.
