How to Convert HEX to RGB Online — Free Tool

Designers and developers constantly move between HEX codes (#RRGGBB), RGB values, and formats like HSL or CMYK. Converting HEX to RGB tells you how much red, green, and blue make up a brand color—essential for CSS, design tokens, and accessibility checks. Use the color converter below to pick or paste a HEX value and see RGB instantly, plus harmonies and export options.

  1. Enter or pick your HEX color

    Type a six-digit HEX code (with or without #) in the base color field, or use the swatch picker to choose visually. Invalid HEX will be caught before you copy values downstream.

  2. Read the RGB output

    As soon as the color is valid, RGB appears in the readout—typically as rgb(r, g, b) with integers 0–255 per channel. You can copy individual channels or the full line for your stylesheet or design doc.

    What you'll see

  3. Copy CSS or export your palette

    Use the copy actions for CSS variables or open the code modal to download theme JSON. Palette harmonies (complementary, triadic, and more) update from your base color so you can build a coherent scheme without manual math.

RGB is ideal for rgba() with alpha in modern CSS; when you need HSL for programmatic adjustments or CMYK for print, the same tool converts in one place. For contrast checking against white or black text, use the preview panels to judge readability before shipping UI.
