About PNG To AVIF Converter Online
PNG (Portable Network Graphics) uses lossless compression and is the standard choice for images that need transparency, crisp edges, or pixel-perfect fidelity — logos, screenshots, icons, and illustrations. PNG files are larger than JPEG for photographs.
Converting to AVIF gives you the smallest possible file size for web delivery while retaining excellent quality. AVIF is supported in all modern browsers and is the recommended format for performance-focused web images.
This tool converts your PNG images to AVIF directly in the browser. Upload your file, choose a quality preset if available, and download the converted result instantly.
