This tool is essential for web developers migrating legacy image assets to WebP, content creators preparing images for platforms with WebP support, and anyone who receives WebP files and needs to convert them back to universally compatible JPG or PNG. All conversions run locally in your browser via Canvas API rendering with zero server uploads.
