- Pick the background color to remove using the color picker — default is white (#ffffff).
- Adjust the threshold slider (0–200) to control how closely pixels must match the target color.
- Adjust the feather slider (0–100) to soften the edges of the removed area.
- Download the result as a transparent PNG — all processing runs in your browser and nothing is sent anywhere.
