What is screenshot annotation?

Annotation refers to a "note of explanation or comment added to a text or diagram" added by editing a screenshot

Screenshot or image annotation is adding labels or comments on a screenshot to give more information or emphasize an area.

Why is screenshot annotation important? 

Including screenshots in your content, help guides or how-to guides can be useful. But sometimes screenshots aren't enough.

Screenshot annotation comes in handy in a few ways:

  • Visual clarity: Draw attention to specific elements in a screenshot, guiding viewers to important details.
  • Emphasis: Point out the important parts of a screenshot. 
  • Context: Add contextual information that explains the purpose or highlights specific areas.
  • Details: Explain a particular part or the whole screenshot image for accuracy.
  • Streamline collaboration: Eliminate lengthy explanations and reduce the chances of misunderstanding.

There are multiple kinds of annotations that can be added to a screenshot, beyond text boxes and basic shapes:

  • Add a text block on a screenshot image, with instructions or details. 
  • Add an arrow to highlight the important information.
  • If the screenshot has multiple steps (or clicks) on the same screenshot, you can add multiple arrows with numbers to show the sequence.
  • Add a circle or square around the section you want to emphasize. You can also combine the squares with arrows or sequence arrows.
  • Color-code different elements in the screenshot to sort or emphasize them. For example, use red to show elements that need to be fixed, blue for new elements, green for accepted elements, etc.
  • If you're annotating a screenshot with sensitive information, blur screenshot details to avoid privacy or security issues. 
  • Use emoji icons to visually represent reactions, priorities or statuses in a fun, visual way.
