ShowDev: I built Hexto – a color converter & accessibility tool for designers/devs

Hey Devs! 👋

I recently launched Hexto, a free, responsive color conversion and accessibility tool for developers and designers.

🧰 What Hexto Does

🎨 Convert instantly between:

• HEX / RGB / RGBA
• HSL / HSLA
• HSB (HSV)
• CMYK

🧪 Includes a built-in WCAG contrast checker

🖼️ Export your color as a PNG swatch image

📋 Copy individual codes or all at once

🔗 Share colors via unique URLs like:

https://hexto.io/?color=%23ffcc00

🕘 Keeps your recent color history

🌗 Toggle light/dark mode

📱 Fully responsive – mobile & iPad ready

✅ No login, no ads, no tracking

🔧 Why I Built It

I needed a single-page, fast tool that worked well on mobile and made it easy to convert + validate colors for frontend work. So I built one!

Hexto has been super useful in my workflow, so I polished it up and made it public.

Would love your feedback or feature ideas 🙌

Thanks!
