Enter a hex code, and the tool expands 3-digit shorthand to 6-digit, or shortens a 6-digit code back down when it's collapsible.
A 3-digit form like #ABC where each digit is doubled, so #ABC expands to #AABBCC. It only works when each channel's two digits match.
No. A 6-digit hex only collapses to shorthand when each pair of digits is identical (e.g. #33AAFF → #3AF); otherwise it stays 6-digit.
Yes — you can paste with or without the leading hash and the tool normalizes the output for you.
