How do I watermark a PDF on Android without an app?

In Chrome — upload, set the mark, download. The stamped copy shares onward from Downloads.

Will the mark show in WhatsApp document previews?

Yes — it is page content; every viewer renders it.

Can I unmark a watermarked file later?

Keep the clean original — that is your unmarked version; the mark is deliberately persistent on copies.

Watermarks in the forwarding chain

Android documents travel through chat-forward chains where context evaporates — the in-document mark is the context that survives. Applying it takes one Chrome pass between receipt and re-share.

The Chrome mechanics

Upload from the file manager, configure text or logo with opacity and position, download the marked copy — the original stays clean for the eventual final version.
