About converting RGB to HEX
RGB and HEX describe the same on-screen color in different notations, and converting between them is everyday work in web and graphic design. This page focuses on RGB to HEX, but shows HEX, RGB and HSL together so you always have every format to hand.
Everything runs in your browser, so it's instant and private — no upload, no sign-up. Edit any field and the others update, including the live preview and the native color picker.
Frequently asked questions
How do I convert RGB to HEX?
Type or paste your RGB value (or pick a color with the swatch) and read the HEX value straight off — it updates instantly. Copy it with one click.
Are the values CSS-ready?
The HEX value sits alongside HEX, RGB, HSL and HSV — copy whichever you need. HEX, RGB and HSL paste straight into CSS; HSV (HSB) is a design-tool notation rather than a CSS function.
Can I convert the other way?
Yes. Every field is editable, so you can go from HEX back to RGB too, or to any other format — they all stay in sync.
Is anything uploaded?
No. All the conversion runs in your browser; nothing is sent anywhere.
