Asymmetry Heatmap

Instantly visualize where your image is unbalanced. The heatmap overlay highlights asymmetric pixels in bright colors, making them easy to spot.

Batch Workflow

Audit entire libraries of icons, logos, or portrait photos in seconds. Process hundreds of images simultaneously without uploading to a server.

Frequently Asked Questions

What is the symmetry score?

The score represents the percentage of pixels that match their mirrored counterparts within the specified tolerance. A 100% score indicates perfect mathematical symmetry.

How does the heatmap work?

The heatmap highlights pixels that do not have a symmetric partner. The brighter the color, the larger the difference between the two sides.

Is my data secure?

Yes. All analysis is performed client-side in your browser. Your images are never sent to our servers, ensuring total privacy for your professional assets.
