WebP is a modern image format that offers both lossy and lossless compression, outperforming JPEG and PNG in efficiency. WebP lossless images are about 26% smaller than PNG, and lossy WebP images are 25–34% smaller than JPEG at similar quality. Using WebP reduces bandwidth usage and improves page load speed, enhancing your website’s user experience. ## What is AVIF? AVIF is a next-generation image format based on AV1 video coding technology, supporting both lossy and lossless compression. It delivers superior compression efficiency and image quality compared to WebP and JPEG. AVIF images often achieve over 50% smaller file sizes than JPEG while maintaining excellent visual fidelity—and are typically smaller than WebP as well. AVIF significantly lowers bandwidth usage and speeds up page loading, offering a faster and sharper visual experience for your website.
