Apply watermarks to all images in a space

Set your space or site to include a watermark on all images. This makes it harder to share proprietary or sensitive images without attribution. You can use an image as a watermark or display the reader’s user ID.

When watermarking is turned on, Confluence overlays a visible watermark on images wherever they appear, including on content you view and in content you export or download. This helps protect intellectual property and discourages sharing without permission.

Set a watermark for a space

Space admins can set watermark for all images in a space. The watermark will be visible to all users visiting the space and on all images downloaded from the space.

To set a watermark, open Space settings, select Look and feel, then Watermark.

1. Select the type:

   • Image: Use an image such as a logo file to apply to all images.

   • User ID: Apply the user ID of the person viewing the page. The user ID is a long series of numbers that identifies an Atlassian account.

2. Select an image file to upload. You will see a preview of the image with current settings.

3. Choose the watermark image’s Position, Opacity %, and Scale %,

   • For User ID watermarks, you can also choose Light or Dark text.

4. Select Save to apply a watermark to all images. You will need to refresh open content to see the watermark.

5. Before you apply your settings, you can choose a background for your preview.

6. If you want to remove the watermark from all images but preserve your settings, select Remove.

Set a watermark for all spaces

Site admins can set a watermark for images across all of Confluence. Select Confluence administration, then select Administration and select Watermark. The settings are the same as above, but apply to all images in every Confluence space.

A watermark set at the space level will override the site-level watermark.
