RGB to Hex Converter

RGB to Hex Converter — Translate Color Values for Web and Design: RGB color model defines every color as a combination of red, green, and blue channels, each ranging from 0 to 255. The hexadecimal format compresses these three decimal values into a six-digit code preceded by a hash symbol, such as #FF69B4. This format is the standard for CSS, HTML, SVG, and most design tools. This free converter transforms your RGB inputs into hex codes instantly, running offline with no signup required ever and returning results in seconds.

Each channel is independently converted to a two-digit hex number. Red 255 becomes FF, green 105 becomes 69, and blue 180 becomes B4, yielding the hex code #FF69B4 (hot pink). The hex digits use 0–9 and A–F, where A = 10 and F = 15. Two hex digits represent values from 00 (0) to FF (255), which maps directly to the 256 levels per channel in the RGB model.

When the alpha channel is set below 100%, the tool outputs an 8-digit hex code (RRGGBBAA) plus the equivalent rgba() CSS function. For example, alpha at 50% produces a semi-transparent version. The alpha hex value is calculated by scaling the percentage to 0–255, so 50% becomes 80 in hex (approximately 128 in decimal). This is useful for overlays, glass effects, and modern CSS compositing.
