Highlight Image Area
Direct attention to one part of an image with a rectangle or ellipse, adjustable outside dimming, and a colored border.
Upload an image, define a rectangle or ellipse, and dim everything outside the selected area.
Rectangle or ellipse
Match the highlight shape to interface controls, products, faces, or circular details.
Adjustable focus
Use exact source-pixel coordinates and dimensions for repeatable placement.
Dimmed surroundings
Control how strongly the rest of the image recedes behind the selected area.

Using highlights clearly
Keep the selected region tight around the important content. Use enough dimming to establish focus without making the surrounding context unreadable. A high-contrast border helps the region remain visible on mixed backgrounds.
