Our AVIF converter uses the browser's native Canvas API with canvas.toDataURL('image/avif'). Everything is processed locally without sending images to external servers. The tool automatically checks if your browser supports AVIF encoding and alerts you if an update is needed. Convert any image to AVIF or convert AVIF files to PNG.
