Color Converter: HEX, RGB, HSL & CMYK Made Simple

Tooly · 2026-08-02 · 5 min read

Designers think in HEX, developers write in RGB, and print shops demand CMYK — and somewhere in between, your brand color gets lost. A color converter translates any color between formats instantly, so your brand looks identical on screen and in print. The best ones run entirely in your browser.

Color formats explained

Format	Used for	Example
HEX	Web (CSS)	`#6366F1`
RGB	Screen / code	`rgb(99, 102, 241)`
HSL	Design tweaking	`hsl(239, 84%, 67%)`
CMYK	Print	`cmyk(59, 58, 0, 5)`

Frequently Asked Questions

Is this color converter really free? Yes — unlimited conversions, no account, no watermark.

Why does my print color look different? Screens (RGB/HEX) show light; print (CMYK) uses ink — conversion gets you close, but print always needs a physical proof.

Is my input uploaded? No — conversion runs entirely in your browser, so your colors stay on your device.

What about palettes? The Color Palette Generator creates harmonious schemes from any starting color.
