How to use RGB to HEX

Enter the RGB values — red, green, blue (0-255 each).
Read the hex code — #FF6600.
Use in CSS, HTML or your design system — hex is the web default.
Reverse it with Hex to RGB when you need rgba() transparency.

What is RGB to HEX?

An RGB to hex converter turns red-green-blue values into a hexadecimal color code: rgb(255, 102, 0) becomes #FF6600. It's the reverse of hex-to-RGB — taking the three explicit 0–255 numbers and packing them into the compact six-digit hex string that CSS and design tools commonly use.

Each RGB number (0–255) becomes two hex digits (00–FF): 255 → FF, 102 → 66, 0 → 00. The result is the hex code preferred for its brevity in stylesheets, HTML and design software.

About the RGB to HEX

Enter RGB values and get the hex code instantly.

Why you'd convert this direction: hex is the CSS/web default — most stylesheets, HTML color attributes and design handoffs use hex (#FF6600), so a color you have as RGB (from a picker, a graphics tool, or code output) often needs converting to hex to fit; compactness — #FF6600 is shorter than rgb(255, 102, 0), and hex is the convention in most front-end code; design tool output — you sampled a color as RGB and need the hex for your brand guide or CSS variables; and consistency — matching the hex format the rest of your codebase or design system uses.

The reverse is our Hex to RGB converter (needed when you want transparency via rgba). For the fuller picture — HSL, color names, and all formats at once — our Color Converter handles everything. Sample colors from images with Color Picker from Image, and build harmonious sets with the Color Palette Generator. Conversion runs locally and instantly.

Frequently Asked Questions

Convert each number (0-255) to two hex digits and concatenate: 255→FF, 102→66, 0→00 → #FF6600. Each channel becomes a hex pair; the tool does it instantly.

Hex is the CSS and web default — most stylesheets, HTML and design handoffs use it for its compactness. A color you have as RGB (from a picker or graphics tool) often needs hex to fit your codebase or brand guide.

RGB channels must be 0-255 — values outside that aren't valid colors. Some contexts use 0-1 float RGB (0.5 instead of 128); multiply by 255 first if your source uses floats.

None — hex color codes are case-insensitive, so uppercase and lowercase are identical. Conventions vary (CSS often lowercase, some tools uppercase); pick one for consistency, but both work everywhere.

Either use 8-digit hex (#FF6600CC, the last two digits being alpha) or convert back to RGB and use rgba(255,102,0,0.8). Both are supported in modern browsers; rgba is more widely familiar.
