What does Color to RGBA do?

Converts a color into a CSS rgba() string with a chosen alpha value. Paste your color on the left and NMSnabbit instantly shows the rgba() on the right. For example, “#3366cc” gives “rgba(51, 102, 204, 0.5)”. Everything runs locally in your browser — nothing is uploaded, so it stays private and works offline. You can process several values at once and copy the result with one click.
