Color Converter — HEX, RGB & HSL Online (Free)

Convert colors between HEX, RGB and HSL instantly with a live preview. Paste any color format and see all three representations — free, in your browser.

All tools run in your browser — nothing you process is ever uploaded.

How to Use

  1. Type a color in any supported format — #3b82f6, rgb(59, 130, 246) or hsl(217, 91%, 60%).
  2. Watch the other two formats update instantly, along with a live color preview.
  3. Copy whichever format you need for CSS, design software or code.

Everything runs locally in your browser. There is no upload, no account and no limit on how many colors you can convert.

HEX, RGB and HSL are three views of the same color. Web developers move between them constantly: a palette from a design tool arrives in HEX, a component needs an rgb() override, and an animation script wants to animate between HSL values. Converting by hand is error-prone — a single wrong digit changes the whole color.

Tips

Shorthand hex like #fff works too. If you type something the tool cannot parse, it tells you instead of guessing — so invalid values never silently produce a wrong color. Use the HSL view when you want to tweak a color’s lightness without disturbing its hue.

Why use it

Design tools and CSS both use color, but rarely the same format. Instead of switching between browser devtools and calculators, this converter gives you every format in one place with a visual check — fast, private and accurate.

Real-world use cases

  • API development: Format JSON responses from Chrome DevTools before committing fixtures.
  • Debugging: Validate timestamps, regex or hashes without switching to a terminal or IDE.
  • On-call fixes: From your phone, quickly convert timezone or generate a UUID for a hotfix branch.

For quick checks without context switching, the browser tool is fastest. For CI, keep the CLI as source of truth.

Pro tips

  • Bookmark the tool. With prefetch enabled, it opens near-instantly next time.
  • For secrets like hashes with salts, prefer your local terminal for production values.
  • Pair UUID/Password generators with your password manager for rotation workflows.

What is the difference between HEX, RGB and HSL?

HEX is a 6-digit hexadecimal shorthand used in CSS and design tools, RGB expresses a color as red, green and blue channels, and HSL describes it by hue, saturation and lightness — which many people find more intuitive for picking and adjusting colors.

Which format should I use in CSS?

All three work in modern CSS. HEX is the most common convention, rgb() is a drop-in equivalent, and hsl() is convenient when you want to adjust lightness or saturation programmatically.

Is it safe to paste production secrets?

Local processing is safer than server tools, but avoid pasting real production secrets anywhere.

Does this work offline?

Yes. After the first load the tool works without network.

Can I use this on mobile?

Yes. All developer tools are responsive and work on phones.
