Convert PNG to AVIF Online
Runs 100% in your browser — your files never leave your device.
PNGs are heavy; AVIF delivers the same picture at a fraction of the size, with transparency support. Where your browser can encode AVIF, this tool produces it locally and tells you plainly when it cannot. Nothing is uploaded.
