Online RGB to HEX Converter

I have always liked a bit of color in my work, but color codes can be tricky. If you have ever tried to copy a color from your graphics app into CSS and gotten a weird result, you know what I mean. Sometimes you get RGB numbers, but your website, plugin, or design tool asks for a HEX code. That is why I created this RGB to HEX Converter. It is simple, fast, and runs right in your browser.

What Is an RGB Value?

RGB stands for Red, Green, Blue. These are the three main colors every screen uses to make every color you see. Each RGB value has three parts. Each one is a number from 0 to 255.

A typical RGB value might look like this:

rgb(255, 102, 0)

Or you might see it written just as:

255, 102, 0

Both represent a bright orange color. Many design tools and apps use the RGB format because it is easy for humans to read and adjust.

What Is a HEX Color Code?

A HEX color code is another way to write the same color, using numbers and letters. It looks like this:

#FF6600

Every HEX code starts with a # and is followed by six hexadecimal digits. Each pair of digits shows how much red, green, or blue is in the color, but using hexadecimal instead of normal numbers.

Why Convert RGB to HEX?

You will need to convert RGB to HEX if you are:

• Writing or updating CSS, which almost always uses HEX for colors
• Copying colors from an app or screenshot tool into your code
• Matching a brand’s color palette between digital tools
• Sharing or saving a color in a way that everyone understands
• Building themes, WordPress plugins, or widgets that need HEX input

Basically, if you design, develop, or even tweak your blog, you will hit both formats. This tool lets you convert quickly without doing mental math or searching for a chart.

What This Tool Does

This tool takes any valid RGB input and converts it to a HEX color code. You can enter your color as rgb(255,102,0), with or without spaces or commas, or just use 255 102 0. It checks your input, makes sure the numbers are in the right range, and gives you a clean HEX code you can copy and use anywhere.

All the conversion happens instantly in your browser. You can run it as many times as you want, for any color, with complete privacy.
