UnitConverterTool.com is designed to be comfortable for extended use and accessible to everyone. Our dark-first design, semantic structure, and privacy-first approach work together to create a tool platform that respects your eyes, your time, and your needs.
— Eye Comfort —
Measurable design choices that protect your vision during extended use.
Our #0A0F1C background emits 95% less blue light than white-background websites, reducing eye strain during extended sessions.
All text meets or exceeds WCAG 2.1 AA contrast ratio requirements (minimum 4.5:1 for body text, 3:1 for large text).
We never use #FFFFFF for body text anywhere on the site. Our lightest text color is #C8D8E8 - bright enough to read, soft enough to not cause glare.
Students, developers, and professionals spend hours with our tools. Every color, spacing, and animation choice is optimized for sustained comfortable use.
— The Difference —
A real visual comparison between traditional tool websites and our approach.
— Color System —
Every color is tested against WCAG luminance formulas. Here's the proof.
