Questions about watermark pdf

Can I put DRAFT or CONFIDENTIAL across every page?

Yes. Set the words, then the size, angle, colour and how much of the page shows through — a bold diagonal stamp or a discreet line in a corner, applied to every page in one pass.

Can the watermark be removed later?

Not from the file you download — it is written into the pages. Keep your original if you will need a clean copy.

Is the document uploaded?

No. The file is opened, changed and written by this browser tab — it is never sent to a server, so there is no queue to wait in and nothing to delete afterwards. Once the page has loaded you can turn the network off and the tool still works.
