This tool works entirely on this page. Your file is opened by JavaScript here, changed in memory, and handed straight back to you — it is never uploaded. Open your browser's Network tab while you use it and you will see nothing leave your device.
Because there is no server doing the work, there is no signup, no watermark, no file size limit, and no daily cap. Nothing is stored, because nothing is received.
