Translate color codes across every format

Developers, designers, and brand teams frequently bounce between HEX, RGB, HSL, and CMYK notations. The Color Converter keeps shades accurate, surfaces WCAG contrast warnings, and generates reusable design tokens so product teams can stay aligned.

Visualize palettes with confidence

Paste any color token or use the eyedropper to sample pixels from screenshots. The converter outputs precise equivalents for digital and print workflows, including alpha-aware RGBA strings, percentage-based HSL values, and CMYK percentages for packaging or signage.

Preview complementary shades, lighter/darker ramps, and accessible text pairings. Because everything renders in real time, you can tweak brand proposals live during reviews instead of guessing hex values from memory.

Contrast insights
Automatic WCAG calculations flag combinations that miss AA or AAA thresholds, helping you correct them before QA does.
Token-ready output
Copy CSS variables, Tailwind config snippets, or JSON tokens that drop straight into your design system repository.

Collaborate across mediums

Brand kits rarely stay digital. Hand off CMYK or Pantone-adjacent values to print vendors while still maintaining the exact RGB counterpart engineers need. Notes and comparisons live right inside the tool so marketing, product, and engineering speak the same language.

Since conversions run client-side, you can experiment without ever uploading proprietary assets. Save swatches locally or pair them with a FreeTools.run Image Converter session to generate optimized preview cards.

Batch mode
Drop in multiple tokens to build palette reference tables that sync with slides or documentation instantly.
Brand annotations
Add usage notes like “buttons only” or “alerts” so downstream consumers understand the intent behind each shade.

Workflow suggestions

Audit handoffs

Use the exported token list in pull requests to prove that implementation matches the latest Figma file.

Local theming

Keep multiple palettes handy while prototyping dark mode, high-contrast, or seasonal themes.

Marketing QA

Share a link with marketing leads so they can validate colors without installing extra software.

Print proofing

Send CMYK readouts in the same email as packaging mockups so printers have everything they need.

Next step

Optimize assets after finalizing colors

Send your polished palette straight into the Image Converter to compress hero graphics, banners, or social previews without sacrificing vibrancy.

Frequently asked questions

What color formats are supported?

We support conversion between HEX, RGB, RGBA, HSL, HSLA, and CMYK formats. You can input any of these, and the tool will instantly calculate the others.

What is Alpha channel?

The Alpha channel represents the opacity or transparency of a color. It is used in RGBA and HSLA formats, where 'A' stands for Alpha. A value of 0 is fully transparent, and 1 (or 255/100%) is fully opaque.

How do I pick a color?

You can type a color code directly into any input field, or use the visual color picker to select a color from the spectrum.

Is this useful for print design?

Yes. We provide CMYK (Cyan, Magenta, Yellow, Key/Black) values, which are essential for print design. However, please note that screen colors (RGB) may look slightly different when printed.

Follow these four quick steps to transform data between ecosystems right inside your browser—no downloads, no accounts, and no data leaving the FreeTools.run sandbox.

Step 1: Load your source data
Paste text, drag a file, or start with our curated sample to understand how the converter workflow behaves with real inputs.
Step 2: Adjust tool options
Toggle presets, update formatting rules, or choose export preferences. All controls update in real time so you can preview the effect before committing.
Step 3: Review the live preview
Use the split-pane preview, inline validation, or diff output to confirm the transformation looks correct before you copy anything back into your project.
Step 4: Export or chain another tool
Copy the result, download a file, or jump into a related FreeTools.run utility (like Diff Checker or the QR Code Generator) to continue the workflow without leaving the browser.
