HEX to RGB Converter
Key Takeaway: Converting HEX to RGB reverses that encoding: it splits a six-character hexadecimal color code into three base-16 pairs and decodes each one back into its matching 0–255 decimal value for the red, green, and blue channels — same underlying color, just read out in decimal instead of hex.
There's no server involved at any point — the decoding happens locally in your browser the moment you type a code or move the color picker.

Common HEX to RGB Examples
| Color | HEX | RGB |
|---|---|---|
| Red | #FF0000 | 255, 0, 0 |

| Black | #000000 | 0, 0, 0 |
| Orange | #FF5733 | 255, 87, 51 |
| Slate | #1A2B3C | 26, 43, 60 |
Why Convert HEX to RGB
Converting HEX to RGB matters because plenty of tools flatly can't consume a hex string — canvas drawing calls, JavaScript color objects, and slider-based pickers all expect three separate 0–255 numbers, so you decode the hex pairs whenever code or a control needs that shape instead.
HEX and RGB are two notations for the exact same colors. HEX is compact and the standard for CSS, HTML, and most design files — a six-character code like #FF5733 is easy to paste and share. RGB breaks that same color into three decimal values (255, 87, 51), which is the format sliders, APIs, and certain design tools report and accept.
You need to convert when the tool in front of you speaks a different dialect than the one that gave you the color. A brand guide delivers a HEX code; the CSS rgba() function needs decimal values to add transparency. A design token uses #1A2B3C; a canvas API or animation library expects rgb(26, 43, 60). This tool handles that translation instantly.
The math is straightforward — each pair of HEX characters is a base-16 number converted to base-10 — and it runs entirely in your browser with no upload required. Paste a HEX code or use the color picker, and the RGB values update in real time.
How HEX to RGB Conversion Works
Converting HEX to RGB splits the six-character code into three two-digit pairs and reads each pair back out as a base-10 decimal number for the red, green, and blue channels.
A HEX color code is six hexadecimal characters split into three pairs, one each for red, green, and blue. Converting to RGB just means taking each pair and reading it as a base-16 number, then writing that same value out in base-10.
For example, the HEX code #FF5733 splits into three pairs: FF, 57, and 33. Converting each pair from base-16 to base-10 gives FF = 255, 57 = 87, and 33 = 51, which together give rgb(255, 87, 51).
Where Code and Design Tools Need RGB Instead of HEX
Plenty of code paths want the decoded decimal channels rather than the compact hex string. The HTML5 canvas 2D API's fillStyle and getImageData pixel buffers work in per-channel 0–255 values, JavaScript color libraries typically expose .r, .g, and .b properties for math like blending or brightness checks, and computing an rgba() overlay from a brand hex color means pulling the three channels back out first. Per the W3C's CSS Color Module Level 4 specification (see CSS Color Module Level 4), hexadecimal notation also supports optional 4- and 8-digit forms, where the extra pair encodes an alpha channel rather than a fourth color channel — so even hex-native workflows eventually need the RGB decomposition once transparency enters the picture.
The decoding itself is a straight base conversion with no rounding involved: a hex pair like FF is read as a two-digit base-16 number and rewritten in base-10, giving 255, and the same logic applies independently to each of the three pairs in a six-character code. According to MDN's documentation on CSS color values (see MDN: CSS color value), each hex digit pair maps directly to its decimal channel value with no gamma correction or color-space adjustment applied in the process, which is why decoding a HEX code to RGB — and re-encoding it back to HEX afterward — reproduces the exact same color every time.
Use Cases
Web Design
Take a HEX brand color from a style guide and get the RGB values some tools and APIs expect instead.
CSS rgba() Opacity
Convert a HEX color to RGB so you can add transparency with rgba(r, g, b, alpha) in CSS.
Graphic Design
Match a HEX swatch from one design tool to the RGB values another tool reports for the same color.
UI/UX Design
Translate HEX codes from a prototype into RGB values ready to hand off to a development team.
HEX vs RGB: Format Comparison
| Feature | HEX | RGB |
|---|---|---|
| Format | Hexadecimal (00–FF per channel) | Decimal (0–255 per channel) |
| Example | #FF5733 | rgb(255, 87, 51) |
| CSS Support | Yes — #RRGGBB and #RGB | Yes — rgb() and rgba() |
| Transparency | No (use rgba or 8-digit hex) | Yes — via rgba() |
| Human Readable | Compact, standard for web | Easier to understand channels |
| Common Use | CSS, HTML, design files | Code, APIs, design tools |
| Color Accuracy | Identical | Identical |
| Free to Use | Yes | Yes |
HEX and RGB represent identical colors — the difference is notation only. Use HEX for CSS and design files; use RGB when you need decimal channel values for rgba() transparency, canvas APIs, or any tool that expects numeric inputs.
Frequently Asked Questions
What is HEX?
HEX is a base-16 (hexadecimal) representation of a color, written as a six-character code like #FF5733. The first two characters represent red, the middle two represent green, and the last two represent blue.
What is RGB?
RGB stands for Red, Green, Blue — a color model that defines a color by mixing three light values, each ranging from 0 to 255, to produce the full range of colors a screen can display.
Why convert HEX to RGB?
Different tools and codebases expect colors in different formats — CSS, HTML, and most design software commonly use HEX, while sliders, code, and some APIs report colors as RGB. Converting lets you move a color between the two without guessing.
How does the conversion work?
Each pair of HEX characters is converted from base-16 to base-10. For example, in #FF5733, FF becomes 255, 57 becomes 87, and 33 becomes 51, giving rgb(255, 87, 51).
Can I use RGB in CSS?
Yes. RGB is one of the most common ways to specify color in CSS, for example background-color: rgb(255, 87, 51);. HEX codes work in CSS too, written as #FF5733.
What if my HEX code has only 3 characters?
A 3-character shorthand HEX code like #F83 expands by doubling each character, so F83 becomes FF8833. This tool detects shorthand codes automatically and expands them before converting.
