FAQs

 

  1. How do I convert RGB to hex? Enter red, green, blue values (0–255), optional alpha, and click Convert. Copy the #hex code.
  2. What is the difference between #RRGGBB and #RGB? #RRGGBB is full 6-digit (e.g., #FF5733); #RGB is shorthand 3-digit when pairs are identical (e.g., #F53).

  4. Does it support transparency (RGBA)? Yes — enter alpha (0–1 or 0–100%), get hex with alpha (#RRGGBBAA).
  5. Is the tool safe for color data? Yes — all conversion happens in your browser; nothing is uploaded or stored.
  6. Why use hex instead of RGB in CSS? Hex is shorter, widely supported, and easier to read/copy in stylesheets.
