What is WebP and why convert images?
WebP is a modern image format developed by Google that delivers smaller file sizes while keeping visual quality high. Compared to JPG and PNG, WebP can reduce file sizes by 25-70% for most web images, which improves page speed, Core Web Vitals, and overall user experience.
Our free WebP converter runs fully in your browser using the Canvas API. That means your images stay on your device, with no server uploads or tracking. You can batch convert multiple images, adjust quality, and resize on the fly to create optimized assets for blogs, product pages, and responsive layouts.
WebP supports transparency like PNG and can replace heavy JPG files for photographs. The converter also provides real file size savings per image so you can make informed quality and compression choices before downloading.
