Masking fits a Google Slides image into a visible shape, such as a circle or another available outline. It is useful for a consistent set of profile pictures or a designed illustration. The mask changes presentation appearance; it does not prove that hidden image areas have been securely removed.
Choose a mask shape
In the desktop editor, select the image. Open the arrow beside Crop and choose the desired shape. Google’s help describes this route for masking images in Slides. Start with a shape that suits the picture’s subject rather than choosing one solely for decoration.
Adjust the visible subject
Use the available colored handles to adjust the mask. Inspect the subject inside the shape, including faces, labels, and other important details. A circular mask can easily cut off information that a rectangular picture previously displayed.
Compare repeated pictures if the slide contains several masked images. Consistent outer shapes do not automatically create consistent subject size or eye level, so review the visible contents as well as the object dimensions.
Check clarity and context
Present the slide and confirm that the mask helps the audience understand the content. Ensure that a caption still identifies the correct picture and that required credits remain visible. If the shape makes a technical screenshot hard to interpret, use a simpler crop or an ordinary rectangular image instead. Keep a properly prepared source image for sensitive material. A stylish mask should not be used to conceal private details that should never have been included in the audience presentation.
