What You'll Need

  • Estimated time: 1-3 minutes

Step 1: Access the Free Image Annotator

Navigate to the Vidocu website and hover over the Tools menu. From the dropdown, select Free Image Annotator to open the annotation tool.

Step 2: Upload Your Image

Scroll to the designated area for image upload and drop your image file there. This will load the image into the annotation workspace, ready for editing.

Step 5: Change Annotation Colors

Adjust the color of your annotations by selecting from the color swatches. Click on a color, such as green or orange, to see how it changes the appearance of your arrows and boxes.
