RGB to HEX Converter
Convert RGB and HSL values to HEX and back, with sliders and a live colour preview. It runs entirely in your browser — no signup, no installation, and nothing you paste or drop leaves your device.
How the RGB to HEX Converter Works
This converter translates between the colour notations you paste into CSS, HTML and design tools. Type a HEX value such as #3366CC, an RGB value such as rgb(255, 0, 0) or an HSL value such as hsl(0, 100%, 50%) into the matching field and the other two are filled in straight away. The red, green, blue and alpha sliders build a colour by hand, and the preview swatch and the read-out lines update while you drag. Values are clamped and rounded instead of being passed through: rgb(300, -5, 0) becomes rgb(255, 0, 0), and alpha is always shown with two decimals. Short forms like #F00, four and eight digit HEX with transparency, and rgba() with a percentage alpha are understood as well. Every result can be copied with one click. Colour names such as tomato are not supported, and colours are not read from images.
