Frequently Asked Questions

Each RGB channel (red, green, blue) accepts values from 0 to 255.

Enter the RGB values and alpha value (0-1). The tool will convert to 8-digit hex format where the last 2 digits represent opacity.
What if my RGB values are percentages?
Convert percentages to 0-255 range first. For example, 50% = 127.5 (round to 128).
