Color Converter
Convert colors between HEX, RGB and HSL
🔒 100% free · no signup · files never leave your device
Colors on the web exist in three main notations, and every project eventually needs all of them. HEX (#3B82F6) is what design tools and brand guidelines hand you. RGB (59, 130, 246) is what CSS filters, canvas code and image editors think in. HSL (217°, 91%, 60%) is the human-friendly one — its hue, saturation and lightness channels map to how designers actually reason, making it far easier to build hover states, dark variants and full palettes by adjusting a single number.
This color converter translates between HEX, RGB and HSL bidirectionally and live: type any format, or use the visual picker, and the other two update instantly with a large swatch preview. One-click copy on every value means no more manual retyping between a Figma file and a stylesheet. With RGBA and HSLA alpha support included, it covers every color conversion a front-end developer or designer hits in daily work.
Why use Color Converter
Moving colors from a design file into CSS
Design tools show HEX, but your stylesheet convention may use RGB or CSS variables — converting once, accurately, avoids subtle mismatches.
Building hover and active states
Convert a brand color to HSL, drop lightness by 8–10%, and you get a predictable darker variant for button hover states.
Generating a full palette from one brand color
In HSL, stepping saturation and lightness produces tints and shades that stay harmoniously on-hue.
Adding transparency to an existing color
Convert HEX to RGBA to set a semi-transparent overlay without changing the base hue.
Pro tips
- Prefer HSL when designing variations: changing only the L channel keeps hue consistent, which is nearly impossible to eyeball in RGB.
- A 3-digit HEX like #48F is shorthand that doubles each digit (#4488FF) — handy for quick mental shortening.
- Check contrast after converting brand colors for text; WCAG requires 4.5:1 for body text regardless of notation.
- When copying from design tools, verify the color profile — an sRGB mismatch can shift values even when the HEX code matches.

Frequently Asked Questions
What formats are supported?▾
HEX (#RRGGBB), RGB/RGBA, HSL/HSLA — all converted live as you type.
What is the difference between HEX, RGB and HSL?▾
HEX and RGB describe a color by how much red, green and blue to mix. HSL describes the same color as hue, saturation and lightness, which makes building tints and shades much easier because you adjust a single number.
Is the conversion exact?▾
HEX and RGB map one-to-one, so those are lossless. HSL uses rounded percentages, so converting to HSL and back can shift a channel by one unit — invisible to the eye, but worth knowing if you compare values programmatically.
