What it will not do
- A watermark drawn above content can still be removed by anyone with a PDF editor. It marks a document; it does not protect one.
Where this runs
Add Watermark runs entirely inside this page. Your file is read by the browser, processed in memory and handed back to your downloads folder. It is never sent to a server, because there is no server involved in this tool.
