This RGB to hex converter turns RGB colour values into hex colour codes, directly in your browser. Enter the red, green and blue values, and get the hex code. No account, no install, so designers and developers can convert colours for web design and CSS on any device in seconds.
How to Convert RGB to Hex Step by Step
- Enter the RGB values. Type the red, green and blue values of your colour into the inputs. Together these define the colour in the RGB system.
- Convert to hex. The tool converts the RGB values into a hex colour code, expressing the same colour in the hexadecimal form used in web design.
- Read the hex code. The hex colour code appears, representing your colour in the compact hex format that web and CSS commonly use.
- Copy the hex code. Copy the hex code to use in your CSS, design tool, or wherever colours are specified in hex.
- Use it in your design. Apply the hex colour code in your web page, stylesheet, or design, having converted your RGB colour into the widely used hex form.
What RGB and Hex Colour Codes Are
Colours on screens are commonly defined in two related ways: RGB and hex. RGB specifies a colour by its red, green and blue components, the three primary colours of light that combine to make any colour on a screen. Hex, or hexadecimal colour codes, express the same red, green and blue information in a compact hexadecimal form. Both describe the same colours, just in different notations, and converting between them is common in web design.
The RGB and hex representations are two notations for the same underlying colour information. An RGB value gives the red, green and blue components as numbers, while a hex code encodes those same three components in hexadecimal, typically as a compact string. Because they represent the same colour, any RGB colour has an exact hex equivalent and vice versa, and converting simply re expresses the colour in the other notation.
Hex colour codes are especially common in web design and CSS, where colours are frequently specified as hex codes. RGB is also used and is often how colours are picked or thought about in terms of their components, but hex is a compact, ubiquitous way to write colours in web contexts. So converting an RGB colour to its hex code is a routine need when you have a colour in RGB terms and need it in the hex form for the web.
RGB to hex conversion is used by web designers and developers constantly, since colours arise in both notations and hex is the common web format. You might pick a colour in RGB, from a design tool, or from another source, and need its hex code for your CSS. Because the conversion re expresses the colour exactly, a converter gives the precise hex code for any RGB colour instantly, making working with colour codes smooth.
RGB Versus Hex for Colours
| Aspect | RGB | Hex |
|---|---|---|
| Specifies | Red, green, blue components | The same, in hexadecimal |
| Form | Numbers for each component | A compact hex string |
| Common in | Picking and thinking of colour | Web design and CSS |
| Represents | The same colour | The same colour |

Frequently Asked Questions
How do I convert RGB to hex?
Enter the red, green and blue values of your colour into the inputs, and the tool converts them into a hex colour code, expressing the same colour in the hexadecimal form used in web design. The hex code appears instantly, representing your colour in the compact hex format that web and CSS commonly use. Copy the complete hex code to use in your CSS, design tool, or wherever colours are specified in hex. Since RGB and hex are two notations for the same colour, the conversion re expresses your colour exactly in the hex form.
What are RGB and hex colour codes?
RGB and hex are two related ways of defining colours on screens. RGB specifies a colour by its red, green and blue components, the three primary colours of light that combine to make any colour on a screen, given as numbers. Hex, or hexadecimal colour codes, express the same red, green and blue information in a compact hexadecimal form, typically as a string. Both describe the same colours, just in different notations. RGB is often how colours are picked or thought about in terms of components, while hex is the compact, common format in web design and CSS.
What is the difference between RGB and hex?
RGB and hex are two notations for the same underlying colour information. RGB gives a colour's red, green and blue components as separate numbers, which is intuitive for picking or thinking about colours in terms of their components. Hex encodes those same three components in hexadecimal, typically as a compact string, which is the common format in web design and CSS. Because they represent the same colour, any RGB colour has an exact hex equivalent and vice versa. So the difference is only in the notation, how the colour is written, not in the colour itself, which is identical.
Why are hex colour codes used in web design?
Because hex colour codes are a compact, ubiquitous way to write colours in web contexts, and are the common format in CSS and web design. A hex code encodes a colour's red, green and blue components in a short hexadecimal string, which is convenient and widely supported for specifying colours in stylesheets and web pages. While RGB is also used and is often how colours are picked in terms of their components, hex is the standard, compact notation for writing colours on the web. This is why converting an RGB colour to its hex code is a routine need when working with web colours.
Does converting RGB to hex change the colour?
No, converting RGB to hex does not change the colour at all; it only changes how the colour is written. RGB and hex are two notations for the same colour, so the hex code produced by converting an RGB value represents exactly the same colour, just in the hexadecimal form. The conversion simply re expresses the identical colour in the other notation. So you can freely convert between RGB and hex knowing the colour stays the same, with only the way it is written changing between the numeric RGB components and the compact hex string. They are exact equivalents.
Can I convert hex back to RGB?
Yes, just as RGB converts to hex, hex colour codes can be converted back to RGB values, since they are two notations for the same colour. Related colour tools handle converting hex codes to RGB, letting you move between the notations in both directions as needed. So if you have a hex code and need the red, green and blue values, you can convert it back to RGB, and if you have RGB and need hex, you convert to hex. This flexibility to convert either way is useful when working with colours across tools and contexts that use different notations.
What should I do if my colours look inconsistent?
To keep colours consistent across your design, use the exact converted hex codes wherever you use a colour, since the hex code precisely represents the intended RGB colour. Inconsistency often arises from using slightly different or incorrectly copied codes, so ensure you copy the complete, correct hex code each time and reuse it consistently. Because the conversion re expresses the colour exactly, using the same converted code everywhere gives consistent colours. If you pick colours in RGB, convert them to hex once and reuse those hex codes, so the same colours appear consistently throughout your web page or design.
Is the RGB to hex converter free?
Yes, it is completely free with no account and no usage limit. You can convert as many RGB colours to hex codes as you like, as often as you like, at no cost. It runs entirely in your browser on any device, so there is nothing to download or install, and the hex colour code appears instantly whenever you enter red, green and blue values, helping designers and developers work with colours in the hex format used throughout web design and CSS.
