Color Converter
Convert between HEX, RGB and HSL with a live preview and one-click copy.
About this tool
HEX, RGB, and HSL are just different ways of writing the same color. This tool converts between them in your browser and shows a live preview, and never sends your color anywhere. Knowing how the notations relate and when to use each makes palette work smoother.
HEX and RGB are the same underneath
#RRGGBB lists the red, green, and blue intensities in hexadecimal (00βFF = 0β255), which is identical to the rgb(0β255, β¦) form. For example, #FF0000 and rgb(255, 0, 0) are the same red. The only difference is that HEX suits web declarations while RGB is easier for calculation and tools.
HSL maps to how people perceive color
HSL specifies a color by hue (a 0β360 degree color wheel), saturation (vividness in %), and lightness (brightness in %). Small tweaks like "a touch lighter but the same hue" or "slightly more muted" are more intuitive in HSL than editing RGB directly.
A round trip can nudge the last digit
Because RGB uses integers while HSL uses degrees and percentages, going RGB β HSL β RGB can shift the last digit due to rounding. It is not visually noticeable, but if you need exact values, treat your original notation as the reference.
Shorthand and transparency
A 3-digit form like #RGB is expanded to #RRGGBB before interpreting. When you need transparency, use rgba() or 8-digit HEX; since this tool centers on opaque colors, add the alpha component to the converted value.
How to use
- Enter a color code in HEX, RGB or HSL format (e.g. #285240).
- The converted formats and a preview appear automatically.
- Copy any format with one click using the button beside it.
FAQ
Are the colors I enter sent to a server?
No. All conversion is calculated in your browser (JavaScript), so the values you enter never leave your device.
Does it support the 3-digit HEX shorthand (#RGB)?
Shorthand like #RGB is normally expanded to #RRGGBB before interpreting. If it is not recognized, try entering the full six-digit form.
When should I use HSL versus RGB?
RGB pairs well with displays and CSS declarations, while HSL is better for intuitive adjustments like changing brightness while keeping the hue. Switch between them as your task requires.
Can it handle transparency (alpha)?
This tool focuses on converting opaque colors (HEX, RGB, HSL). If you need rgba() or 8-digit HEX with transparency, add the alpha component to the converted value.
Can the color shift slightly after converting?
Rounding occurs when converting between RGB and HSL, so a round trip may nudge the last digit slightly. It is not visually noticeable, but if you need exact values, treat your original notation as the reference.
Can I pick colors like a color picker?
The tool centers on entering and editing values directly. By adjusting the numbers while watching the live preview, you can dial in the color you want.
