Result
How it works
- Upload or select your image.
- The frame is analyzed for subject vs. open space.
- See the negative space percentage and a suggested overlay zone.
The method
Regions of high visual complexity are treated as the likely subject, with the remaining flatter area estimated as negative space available for overlays.
FAQ
Why does negative space matter for image selection?
Negative space gives designers room to add text, logos, or UI elements without covering the subject — images with too little negative space often look cramped once overlays are added.
How is the subject area estimated?
The image is analyzed for regions with high visual complexity or contrast versus flatter background regions, giving a rough estimate of how much of the frame the subject occupies.
What is this useful for?
Choosing hero images for a website, picking photos for a poster or ad, or evaluating whether an image will work well with a text overlay.
