Stamping the purpose onto a copy of an ID or a contract before sending it helps stop the file being reused elsewhere.

Does it work with non-Latin text?

Yes. The built-in PDF fonts have no Hangul, kana or Han characters, so passing them straight in fails — the text is drawn as an image and laid on instead.

Can the watermark be removed?

It is laid on as an image, so it is hard to remove by ordinary means. It is not, however, real protection.
