Frequently Asked Questions
Does it support 8-digit HEX with alpha transparency?
Yes, both 4-digit (#RGBA) and 8-digit (#RRGGBBAA) hex codes are parsed automatically to extract the alpha opacity channel.
What is Modern CSS Color 4 syntax?
Modern CSS Color Level 4 uses space-separated channels like rgb(79 70 229 / 85%) instead of comma-separated rgba(). It is supported across all modern browsers.
Can I convert multiple hex codes simultaneously?
Yes, use the Batch Converter tab to paste a list of HEX codes, design tokens, or CSS snippets. You can copy the results as CSS variables, JSON, or Tailwind config.
How does the WCAG contrast auditor work?
It calculates the relative luminance of your color against pure white (#FFFFFF), black (#000000), or any custom background, evaluating AA and AAA compliance for normal and large text.
