Questions

Are my files uploaded to a server?

No. Everything runs inside your browser, so your files never leave your device. Close the tab and nothing is left behind.

Does it work with non-Latin text?

Yes. The text is drawn with the fonts on your device, so any script your system can display — Chinese, Arabic, Cyrillic, emoji — will work.

Can the watermark be removed?

It is drawn into the page content, so ordinary PDF readers can’t simply delete it. It is a deterrent, though, not an anti-forgery measure.
