MP4 to HLS Converter (Free, Online, No Upload)
Convert any MP4 file to HLS streaming format right in your browser. Nothing gets uploaded to a server. HLS (HTTP Live Streaming) breaks your video into small segments with a playlist file, enabling adaptive bitrate streaming on Apple devices and most modern players. The conversion runs locally on your device.
