How do I make a color transparent in an image?

Upload your image, click on the color you want to make transparent, adjust the tolerance slider to control how similar colors are affected, then click "Apply Transparency" and download the result as PNG.

What is the tolerance setting?

Tolerance controls how similar a pixel must be to your selected color to become transparent. A low tolerance (0) only affects exact color matches, while a high tolerance (100) makes a wider range of similar colors transparent.

Why is PNG the only output format?

PNG is the only common image format that supports transparency (alpha channel). JPEG and BMP do not support transparency, so only PNG can preserve the transparent areas you create.

Can I pick a color manually instead of clicking?

Yes! You can use the color picker input to manually select any color, or type a hex color code directly. Both methods work alongside clicking on the image.

Is my image uploaded to a server?

No. All image processing happens locally in your browser using the Canvas API. Your images never leave your device.

Make Color Transparent
