Insert the Graphic or Picture on the Slide
Begin by adding the picture you want to use as the watermark. You have two options:
Insert your own picture that is stored on your computer. Select Insert > Pictures. In PowerPoint for Mac, select Insert > Picture > Picture from File. Insert an online graphic. Select Insert > Online Pictures.
Move and Resize the Graphic or Picture
If the watermark is for a company logo, move it to a specific corner on the slide so that it doesn’t interfere with the text on the slide. If the image is too big or too small, resize it.
To move a picture, select the image and drag it to the new location.
To resize a picture, drag a corner selection handle to enlarge or reduce the size of the photo. Use a corner selection handle to maintain the proper proportions of the picture.
Format the Picture for a Watermark
To make the picture less distracting on the page, format it to fade the image.
Select the picture. Select Picture Tools Format > Color to open a list of color variations. Hover over a color variation to see a preview on the slide. Choose Washout.
Send the Watermark to the Back
When your watermarked slide contains text, the watermark may appear on top of the text. If the watermark covers text, move the watermark behind the text.
Select the watermark. Select Home > Arrange. Select Send to Back. The watermark picture moves behind the text and will stay behind any new elements that are added to the slide.
