Color Converter
Convert colors between HEX, RGB, and HSL.
Design handoffs and codebases use different color notations. A designer sends #3B82F6, your CSS needs rgb(), and your design tool shows HSL sliders. Utilitoo's Color Converter translates between HEX, RGB, and HSL instantly so everyone works from the same color values.
Frontend developers copy HEX from Figma into CSS variables, designers convert brand palettes to HSL for theme adjustments, and accessibility reviewers check contrast by inspecting RGB components. Stop manually calculating channel values or guessing hue rotations when building dark mode themes.
Enter a value in any supported format and see equivalent representations immediately. Useful when migrating design tokens, debugging Tailwind config colors, or matching a screenshot hex to stylesheet values in a component library.
Conversion runs locally in your browser on Utilitoo. No uploads, no accounts, no tracking. Free and privacy-first for UI developers, designers, and anyone bridging design tools and production code. Design system maintainers mapping Figma tokens to CSS custom properties use conversion to keep brand colors consistent across web, mobile, and email template codebases. Utilitoo is especially helpful when you inherit a codebase with mixed color formats and need to normalize values before refactoring theme variables. As part of Utilitoo's free, privacy-first toolkit, this page requires no sign-up and keeps your work on your device.
Color Converter handles values you already know - typed HEX codes, rgb() from stylesheets, or pasted design tokens. When the source is a picture instead of text, start with Image Color Picker to sample the pixel, then return here to convert or refine the result. Together they cover the two most common color workflows on the web.
Common use cases
- Converting Figma or Sketch HEX values to rgb() for CSS custom properties.
- Translating brand palette entries between HEX, RGB, and HSL for design system docs.
- Checking HSL lightness before generating hover or dark-mode variants in Tailwind config.
- Decoding color values pasted from browser DevTools during UI debugging sessions.
- Cross-checking typed color output after sampling a pixel with Image Color Picker.
Tips & common mistakes
Color Converter accepts HEX (#6366f1 or #636) and rgb(r, g, b) input. After picking a color from an image with Image Color Picker, paste the HEX here to see all format equivalents. HSL is especially useful when you need to adjust saturation or lightness without guessing channel math. All conversion runs locally in your browser on Utilitoo.
Common errors
- Invalid format - use #RRGGBB or rgb(r, g, b) with integers from 0 to 255.
- Missing hash on HEX - three- and six-digit hex values work with or without a leading #.
- Out-of-range RGB channels - values above 255 or below 0 are rejected.
How to use

Frequently Asked Questions
How do I convert HEX to RGB online?▼
Paste a HEX color like #FF5733 into Utilitoo and the tool displays the equivalent RGB and HSL values instantly.
What is the difference between HEX and RGB?▼
HEX uses a six-digit hexadecimal code prefixed with #. RGB expresses the same color as red, green, and blue values from 0 to 255.
When should I use HSL instead of RGB?▼
HSL makes it easier to adjust hue, saturation, and lightness for themes, hover states, and accessible color variations.
Can I convert shorthand HEX like #FFF?▼
Yes. Utilitoo accepts standard three-digit and six-digit HEX formats and converts them to full RGB and HSL.
Does this color converter upload my palette?▼
No. All conversions happen locally in your browser. Your colors are never sent to Utilitoo servers.
