Google Meet watermarks place identifying text over video and presentations to help trace unauthorized visual copies. The overlay includes the meeting code and the viewer’s email address. It is a traceability measure, not a guarantee against copying or editing, and enabling it can exclude participants whose devices do not meet the requirements.
Check eligibility and participant compatibility
The feature requires an eligible work or school Workspace subscription. Ask the administrator if it is missing. Participants must be signed in and use an updated Chromium browser or the latest mobile app. Google says Firefox is unsupported; unsupported browsers cannot show incoming video or presentations after watermarks are enabled. Mobile users can view watermarks but cannot enable them.
Enable the control from a computer
In the meeting, open Host controls and turn on Add a watermark. If joining from a conference room, Google says watermarks can be enabled through Companion mode. Read any warning that people will be removed because they do not meet technical requirements. Coordinate with the organizer and affected participants before choosing whether to cancel or proceed.
Verify the overlay and its limits
Confirm that supported viewers can see the required presentation and the watermark. Google says watermarks cannot be used while recording or live streaming; starting either disables the watermark. Recheck the protection if the event changes into a recorded or streamed session. An image-editing program can remove the overlay, so do not describe it as a technical block on screenshots or leaks. Keep audience selection, sensitive-content handling, and any capture policy in place alongside the visual marker. A watermark setting alone does not establish that a meeting is safe for every kind of confidential material.
