Watermark a deck

Lay identifying text over a presentation so a forwarded copy names its reader. One checkbox and one text field in Settings.

A watermark lays identifying text over the presentation: a quiet reminder that this copy belongs to a specific reader. Use it for pricing, unreleased work, or anything you would rather not see forwarded around.

Turn it on

1. Open the presentation's Settings.
2. Tick Watermark overlay.
3. Enter your text in the Watermark text field, then click Save.

Watermark overlay lives with the gates in Settings.

The overlay is applied when the presentation is served, so a change takes effect on the live link right away: edit the text or untick the box and the next open reflects it. The file you uploaded is untouched, and the link your reader holds never changes.

What to write

The text is yours. Keep it to a few words: short text stays legible where a full sentence turns to noise. Three patterns that earn their place:

• Confidential: the plain deterrent.
• Prepared for Acme Co: the copy reads as theirs, which makes passing it along feel like handing over something with their name on it.
• A date: an old forwarded copy identifies itself as out of date.

Watermarks deter, gates prevent

Be honest with yourself about what an overlay does: it discourages sharing, it does not prevent it. Anyone who can read the deck can screenshot it. When the material genuinely must not travel, combine the watermark with a password or email gate so you decide who opens it in the first place, and send each recipient their own link from Personalized tracking links in Settings so every view is attributed to a person. The watermark then does its real job: reminding the reader that the copy in front of them is theirs.
