About Image to AVIF
Convert JPG, PNG and WebP images to AVIF, the next-generation image format that often beats WebP on file size at the same quality. AVIF is a great fit for hero images and photo-heavy pages where every kilobyte affects load time. Choose the quality, convert, and see how much you saved. Encoding runs in your browser using its built-in AVIF support.
