About the Binary Converter
Text becomes binary through a character encoding — each character maps to a code point, which is then written in base two. This converter uses UTF-8, so accented characters and emoji convert correctly rather than turning into question marks. The numeric modes handle base conversion directly, which is handy for reading colour values, permission bits and low-level debugging output.
Frequently asked questions
How do I convert text to binary?
Each character is turned into its UTF-8 code point and written in base two, usually as eight-bit groups.
Does it support hexadecimal?
Yes — hex, binary and decimal convert in any combination.
Are emoji and accented characters handled?
Yes. UTF-8 encoding is used, so multi-byte characters convert correctly both ways.
How do I convert text to binary by hand?
Look up each character's ASCII or Unicode code point, convert that number to base 2, then pad it to eight digits. The letter A is 65, which is 1000001, written as 01000001. Doing that for a whole sentence is why a converter exists.
