RGB to Hex Converter
Instantly convert RGB values to HEX color codes. Supports standard RGB (rgb()) and RGB with alpha (rgba()) formats.
Understanding RGB Format
RGB (Red, Green, Blue) is a color model used in digital displays. Each component ranges from 0 to 255, representing the intensity of that color channel. Combining different intensities creates millions of colors.
RGB Format Options
rgb(red, green, blue)
rgba(red, green, blue, alpha)
rgb() - Standard format with values 0-255
rgba() - With alpha transparency (0-1)
Why Convert RGB to HEX?
Compact Format
HEX codes are shorter (6 chars vs ~15) and easier to share or store in databases.
Universal Support
HEX is widely supported across all design tools and browsers.
Design Tools
Many design tools like Photoshop, Figma, and Sketch primarily use HEX.
Developer Friendly
HEX is easier to use in code, config files, and terminal outputs.
RGB to HEX Examples
| RGB Value | HEX Code | Color |
|---|---|---|
| rgb(255, 255, 255) | #FFFFFF | |
| rgb(0, 0, 0) | #000000 | |
| rgb(255, 0, 0) | #FF0000 | |
| rgb(0, 255, 0) | #00FF00 | |
| rgb(30, 144, 255) | #1E90FF | |
| rgba(255, 0, 0, 0.5) | #FF000080 |
How It Works
Converting RGB to HEX is a straightforward mathematical process:
- Take each RGB value (0-255)
- Convert to hexadecimal (00-FF)
- Combine with a # prefix
FAQ
Does this work with RGBA (alpha channel)?
Yes! Use the alpha slider or enter rgba(255, 0, 0, 0.5) format. The result will be an 8-digit HEX with alpha (#RRGGBBAA).
What's the difference between #FF0000 and #F00?
Both represent the same red color. #F00 is a shorthand where each digit is doubled (#FF0000). Our converter outputs the full 6-digit format for clarity.
