How It Works
This tool removes backgrounds from images using pixel-level analysis in the Canvas API. Four methods are available:
- Color Key: Pick a color (click on the image or use the color picker), and all pixels within the tolerance range will become transparent. Works best with solid-color backgrounds.
- Luminance (light): Removes bright pixels (white/light backgrounds). Adjustable threshold.
- Luminance (dark): Removes dark pixels (black/dark backgrounds).
- Edge Detect: Attempts automatic foreground/background separation using contrast analysis. Best for high-contrast images.
The Edge Softness slider controls how gradually the transition fades at the boundary (anti-aliasing). The Before/After slider lets you visually verify the result.
For complex backgrounds (natural scenes, gradients), consider a dedicated AI-powered service. This tool works best with solid or near-solid backgrounds.
