About this converter

PNG files are lossless but large. A single 1920x1080 PNG can easily be 2-5 MB. AVIF compresses that same image down to a fraction of the size while keeping transparency and near-identical visual quality. This converter draws your PNG onto an HTML Canvas and encodes it as AVIF using your browser's native AV1 encoder. No external libraries, no server processing. Your image never leaves your device.
