How to use the RGB to Hex Converter

  1. 1

    Any rgb(r, g, b) or rgba(r, g, b, a) — even loose formats like '255 100 50' work.
  2. 2
    Read the hex value
    Updates live. 8-digit hex is used when an alpha value < 1 is present.
  3. 3
    Copy
    Click Copy or select the output.

Hex vs RGB — when to use which

Hex codes are compact (#7755FF), good for design files, brand systems and pasting into Tailwind / SCSS variables. RGB function notation is more readable and lets you adjust channels arithmetically.

Modern CSS supports both interchangeably. For colours with transparency, use 8-digit hex or rgba() — both encode the same alpha channel.
