FAQ
Are my files uploaded anywhere?
No. The watermark is applied in your browser using JavaScript. Your PDF never leaves your device.
Can I use an image as a watermark?
Not yet -- this tool currently supports text watermarks only.
Can I remove the watermark afterwards?
The watermark becomes part of the page content, the same way most watermarking tools work. Keep your original file if you may need an unmarked copy later.
