Adding an image watermark

Last Updated:

The watermark feature superimposes an image, consisting a meeting participant’s email address, onto the shared content they are viewing and over their video in most video layouts (Speaker, Gallery, Side-by-side). You can also display several instances of the watermark so that it's more visibly apparent across the video or shared screen.

This feature secures the information that you share during a meeting and ensures that shared or confidential content belongs to you.

Notes:

  • To use the watermark feature, account owners and admins must first enable Only authenticated users can join meetings, or when you schedule a meeting/webinar, at the user level, you can enable Require authentication to join. This will require participants to be authenticated before joining the meeting. 
  • This feature is only available through the Zoom web portal. Other scheduling methods, such as the Zoom desktop client or the Microsoft Outlook plugin or add-in, do not support having this option available with additional options, even when Require authentication to join is enabled.
