What does the RGB to HEX Converter do?

Each RGB channel (0–255) is converted to two hexadecimal digits and joined: rgb(79, 70, 229) → #4F46E5. Add an alpha value below 1 to get an 8-digit HEX code with transparency.

The bulk box accepts lines like rgb(255, 87, 51) or 0,128,255 and converts them all at once.

How to use the RGB to HEX Converter

  1. Enter R, G and B values (0–255) and optional alpha.
  2. Copy the HEX code.
  3. For many colours, paste them into the bulk box.
