How to Add a Watermark in Google Slides

How to Add a Watermark in Google Slides | Quick Tips & Tutorial for your presentations

A watermark is a little identifying image used as a fixed element in digital creations such as photos, documents, videos or, in this case, presentations. It helps protect that creation and prevents plagiarism or uses without attribution. In this Slidesgo School tutorial, you’ll learn, step by step, how to insert a watermark into your presentation.

Adding a watermark to a slide

  • Open your Google Slides presentation and select the slide where you want to add a watermark.
  • Click Insert → Image. 
    You’ll see different options to insert an image, such as Upload from computer, Search the web, (Google) Drive, (Google) Photos, By URL and Camera. In this case, we’re going to upload an image from the computer.

  • After inserting the image, resize it however you want. Watermarks tend to be small and are usually placed close to a corner so that they aren’t distracting.
