Color Converter Online — HEX to RGB, RGB to HSL, WCAG Contrast Checker
Convert color formats
Color name: #4B7BEC→Royal Blue
Click a swatch to use it
Convert colors instantly between HEX, RGB, and HSL formats with a live color picker and a recent-colors history so you can jump back to a shade you sampled earlier without re-typing the value. A built-in WCAG contrast checker compares any foreground/background pair and shows the exact contrast ratio alongside pass/fail badges for AA Normal (≥4.5), AA Large (≥3.0), AAA Normal (≥7.0), and AAA Large (≥4.5), so you can verify accessibility before shipping — a one-click swap button flips fg/bg to test both directions. Use it to keep brand colors consistent across Figma designs and CSS, hand off design tokens to developers, run accessibility audits on existing pages, or pick a readable text color for any background. The converter is perfect for designers and developers who switch between color formats daily and need accurate, copy-ready values for CSS, Tailwind, or design tools. Everything runs 100% locally in your browser — no color values are sent to a server.
Convert colors and verify WCAG contrast in one tool
Type a hex, RGB, or HSL value and instantly get all three formats plus a color picker for fine-tuning, with recent colors saved to a history strip for quick recall. The built-in WCAG contrast checker lets you pick a foreground and background color, swap them with one click, and shows the exact ratio like "4.52 : 1" next to pass/fail badges for AA Normal (4.5), AA Large (3.0), AAA Normal (7.0), and AAA Large (4.5). Use it before shipping a button, a hero banner, or a chart series to guarantee accessibility compliance on the first try.
Local palette management for design systems and brand work
Brand palettes, design tokens, and unpublished product colors never leave your browser — the converter runs entirely locally with no API calls and no cloud sync. That matters when you are working on a confidential rebrand, an embargoed product launch, or a client proprietary color system that cannot be shared with a third-party color tool. Save your recent colors and reuse them across sessions without an account.
