What kind of images work best?

Images with solid, uniform backgrounds work best — white, black, or green screen backgrounds. Complex, gradient, or multi-color backgrounds give poor results with this algorithm.

Is this tool AI-based?

No. This tool uses a corner-sampling flood fill algorithm, not AI. It works well for simple backgrounds but cannot handle complex scenes like hair, fur, or gradient backgrounds.

What format is the output?

The output is a PNG file with an alpha channel (transparency). PNG is the only web format that fully supports transparency.

How Background Removal Works

The algorithm samples the corner pixels of your image to detect the background color. It then performs a flood fill, making all pixels within the tolerance threshold transparent. The result is exported as a PNG file with an alpha (transparency) channel.

Limitations

This is a simple color-based algorithm, not AI. It works best when the background is a single solid color and clearly distinct from the foreground subject. For hair, fur, or complex edges, adjust the tolerance carefully or use an AI-based tool for production use.
