Remove a simple solid-color background

This tool is a basic color-key remover, not an AI segmentation tool. It begins with the upper-left pixel as the default background color, then removes pixels close to the selected color according to the tolerance slider.

How to use this tool

Choose an image with a mostly uniform background, ideally contrasting with its subject.
Check the Background Color To Remove control and adjust it if the sampled corner is not representative.
Increase tolerance gradually while checking subject edges in the preview.
Export as PNG to preserve transparent pixels.

Practical tips

If the subject has the same color as the background, it may become transparent too.
A smaller tolerance protects neighboring colors but leaves more background fringe.
For complex hair, shadows, patterned rooms, or multiple background colors, use a dedicated masking workflow.

Common questions

Is this an automatic AI background remover?

No. The current version removes pixels that match one selected color within a tolerance.

Why is part of the subject missing?

The subject and background may have similar colors; lower the tolerance or change the target color.

Limitations: The algorithm treats matching pixels throughout the image, not only the connected background. Review the output before using it commercially.
