- How does RGB to hex conversion work?
- Each channel value from 0-255 is written as a two-digit hexadecimal number, then joined as #RRGGBB. For example rgb(59, 130, 246) becomes #3b82f6.
- What values are accepted?
- Whole numbers from 0 to 255 for each of the red, green and blue channels — the standard 8-bit-per-channel range used in CSS and design tools.
- Does it show a color preview?
- Yes. A live swatch updates as you type so you can confirm the color before copying the hex code.
- Does this need an internet connection?
- Only to load the page. The conversion itself runs in your browser, so nothing you enter is sent anywhere.
