Important limitations
A watermark is a visual label, not encryption or access control. Do not rely on it to protect sensitive content. Keep text short for best placement.
Privacy and file handling
This tool is designed to process supported files locally in your browser; the static website does not provide server-side file storage. Your browser still downloads the JavaScript libraries required for some operations from third-party content delivery networks. See the Privacy Policy for details. Do not use the output without checking it, and keep your original file.
