PNG files are typically the largest images on any website. AVIF, based on the AV1 video codec, compresses dramatically better while still supporting the alpha transparency that makes PNG essential for logos and UI graphics.
Converting your PNGs to AVIF can reduce image weight by well over half, which translates directly into faster page loads, better Core Web Vitals, and improved search rankings.
All modern browsers display AVIF natively, and major CDNs and platforms serve it by default. For maximum compatibility, serve AVIF first with WEBP or PNG fallbacks.
Fublix's PNG to AVIF converter runs the entire encoding process inside your browser using WebAssembly. Nothing is uploaded, stored, or processed on any server.
Your images stay on your device from start to finish - private by design, free, and unlimited.
