RGB to HEX Converter

Convert RGB to HEX in Real Time

The RGB to HEX converter turns red, green and blue values into a web-ready HEX code as you adjust them, with a live color preview. Paste a HEX code into the reverse box and it loads the matching RGB instead — conversion both ways, instantly.

How to Use It

1. Drag the Red, Green and Blue sliders (0 to 255 each).
2. Watch the HEX code and preview update live.
3. Tap the HEX or RGB box to copy the value.
4. To go in reverse, paste a HEX code into the bottom field to set the sliders.

How the Conversion Works

Each RGB channel (0 to 255) becomes a two-digit hexadecimal number (00 to FF), and the three are joined into #RRGGBB:

Channel	Decimal	Hex
Red	124	7C
Green	58	3A
Blue	237	ED

Result: #7C3AED

Black is rgb(0, 0, 0) → #000000, and white is rgb(255, 255, 255) → #FFFFFF.

Why You Might Need It

• CSS and HTML use HEX codes, but design apps often give you RGB.
• Sampling a screen color frequently returns RGB values you need as HEX.
• Matching a brand color across tools that use different formats.
• Learning how the two notations relate, channel by channel.

Tips

• Use the sliders to fine-tune a shade visually rather than guessing numbers.
• The preview’s text color flips automatically so the HEX stays readable on light or dark backgrounds.
• Shorthand HEX like #0AF works in the reverse field and expands to #00AAFF.

Everything runs locally in your browser, so conversions are instant and private. Whether you are translating a designer’s RGB spec into CSS or pulling a HEX code back into an RGB value, this converter handles both directions without a reload.
