RGB to Integer Converter
Pack RGB color values into a single 24-bit integer (used in many graphics APIs and game engines).
How to use this tool
- Enter red, green, and blue values (0–255 each).
- The tool computes the 24-bit packed integer and its hex string.
- Use the decimal integer in APIs that accept packed 0xRRGGBB values.
Pack R, G, B values into a single integer: color = (R << 16) | (G << 8) | B. Common in game engines, OpenGL, and low-level graphics APIs.
Frequently asked questions
- How is an RGB color packed into an integer?
- Red occupies bits 16–23, green bits 8–15, and blue bits 0–7. The formula is: (R << 16) | (G << 8) | B.
- What range can the integer be?
- 0 (black) to 16,777,215 (white, 0xFFFFFF) for 24-bit RGB.
