How To Use

4. Click Preview first image to test the settings on one file.
5. Click Process all, then download the finished PNG or WEBP files as a ZIP.

Choosing Colors

• Use the color picker for quick visual selection.
• Enter a HEX value if you already know the exact color.
• Enter RGB values when you need precise red, green, and blue numbers.
• Use the dropper on the first image to select an exact pixel color from your artwork.
• Choose Transparent as the color to be replaced or as the replacement color.

Rule Settings

• Tolerance controls how close a pixel must be to the selected color. Higher values replace a wider range of similar colors.
• Edge Feathering softens the transition around replaced pixels. Use 0 for crisp, exact edges.
• Fringe Removal expands the selected area slightly to catch leftover edge pixels.
• Fringe Passes controls how strongly that cleanup is applied.

Tips

• For flat artwork or graphics, start with a tolerance around 50 and edge feathering at 0.
• For anti-aliased edges, increase tolerance or add one fringe pass.
• Rules run from top to bottom, so put your most important or most specific replacement first.
• Your files stay on your device. The tool processes images locally in your browser.
