Frequently Asked Questions
What does removing the alpha channel do?
The alpha channel stores transparency. Removing it flattens the image against a background color, making all pixels 100% opaque.
Can I choose the background color?
Yes! You can choose any solid color (white, black, hex code) or even a gradient to fill the transparent areas.
Is the quality preserved?
Yes, the opaque parts of your image remain untouched. Only the transparent pixels are filled with your chosen color.
