Color Converter (HEX/RGB/HSL)

Quick answer: Color Converter (HEX/RGB/HSL) is a free online hex to rgb converter that lets you convert any color between HEX, RGB, HSL, HSV, and CMYK — paste a hex code, rgb(), or hsl() value and get every format instantly. No account or install needed — it runs entirely in your browser, free.

Convert any color between HEX, RGB, HSL, HSV, and CMYK — paste a hex code, rgb(), or hsl() value and get every format instantly.

What is the Color Converter (HEX/RGB/HSL)?

Digital color lives in several competing formats, and every design or development task seems to demand a different one: CSS happily takes hex and rgb(), design tools export HSL, print workflows need CMYK, and color pickers often show HSV. A color converter translates a single color between all of these models so you never do the math by hand. Paste a hex code like #4F46E5, an rgb() value, or an hsl() value, and this tool returns the equivalent HEX, RGB, HSL, HSV, and CMYK representations in one glance.

Under the hood the conversions are exact arithmetic on the same underlying color: hex is just RGB written in base-16, HSL rearranges RGB into the more human-friendly hue/saturation/lightness, HSV is the variant most pickers use, and CMYK approximates the color for print inks. One honest caveat: CMYK is device-dependent and this conversion is an approximation — always proof printed swatches before final artwork. The converter also normalizes shorthand hex (#f00 becomes #ff0000) and clamps out-of-range values. Like every tool here, it runs entirely in your browser with no signup.

How to use the Color Converter (HEX/RGB/HSL)

  1. Paste your color into the input — #4f46e5, #f00, rgb(79, 70, 229), or hsl(243, 75%, 59%) all work.
  2. Click Convert to see the color expressed as HEX, RGB, HSL, HSV, and CMYK.
  3. Copy whichever format your task needs straight from the result cards.
  4. Use the values directly in CSS, design tools, or print software.

Color Converter (HEX/RGB/HSL) use cases

CSS development

Convert a designer’s hex swatch into rgb() or hsl() for use with opacity and color-mix(). HSL is especially handy when you need hover states — just nudge the lightness value.

Print preparation

Get a CMYK approximation of a screen color before sending artwork to a printer. It won’t replace a real proof, but it flags colors that will shift badly in print.

Design handoff

Translate between the formats different tools export so developers and designers stay in sync. One source color, every notation, zero transcription errors — everyone works from the same value, so nothing gets lost in translation.

Theming

Move a brand color from hex into HSL, where adjusting lightness for hover states or dark mode is a one-number change instead of a guessing game. Dark-mode variants become a simple lightness shift rather than a new round of eyeballing.

Learning color theory

See how one color decomposes across every major color model side by side — the fastest way to build intuition for how hue, saturation, and lightness relate to RGB. You will quickly develop an instinct for how the models map to each other.

Tips

  • Shorthand hex like #f00 is expanded automatically to #ff0000.
  • Hex digits are case-insensitive; the tool normalizes output to lowercase.
  • CMYK values here are a standard naive conversion — fine for reference, not a substitute for a real ICC-profile proof.
  • For accessible text colors, pair this with the contrast checker before shipping.

Frequently asked questions

What is the difference between HEX, RGB, HSL, HSV, and CMYK?
HEX and RGB describe the same thing — red, green, and blue light intensities — with hex writing them in base-16. HSL and HSV rearrange those values into hue plus saturation/lightness or value, which humans find more intuitive. CMYK describes ink coverage (cyan, magenta, yellow, black) for print instead of light.
Is converting between formats lossless?
Between HEX, RGB, HSL, and HSV, yes — they describe the identical color, just in different coordinates, so round-trips are exact up to rounding. CMYK is the exception: converting RGB to CMYK and back can shift the color because print gamuts are smaller than screen gamuts.
What color formats can I paste in?
The tool accepts 3- and 6-digit hex (#f00, #ff0000), rgb() and rgba() with 0–255 values, and hsl() with degrees and percentages. The alpha channel is ignored since these conversion models are opaque. If your color uses another notation, convert it to one of these first.
Why do my CMYK numbers differ from Photoshop's?
Professional tools convert through ICC color profiles that model specific printers, inks, and paper. This converter uses the standard profile-independent formula, which is a useful approximation but not a press-accurate prediction. For final print work, always trust a calibrated proof over any online converter.
What does the K in CMYK stand for?
Key — the black ink plate. Black text and shadows print cleaner with real black ink than by overprinting cyan, magenta, and yellow, so K gets its own channel. It is called the key plate because it carries the image's detail and contrast.
Can I convert named CSS colors like red?
The input accepts hex, rgb(), and hsl() notations. For named colors, use your browser's devtools or a color picker to get the hex value first, then convert it here — most pickers reveal the hex in a single click. It takes only a moment.
Does the tool store the colors I convert?
No. Conversion is pure arithmetic done in your browser, so there is nothing to store in the first place. Nothing is uploaded, saved, or tracked, and closing the tab erases every trace of your session. Your palette choices remain completely private.
