How to Write Your Name in Binary Code
Convert your name to binary letter by letter using ASCII — with a worked example.
The idea: each letter is a number
Every letter has an ASCII code: uppercase “A” is 65, “B” is 66, and lowercase “a” is 97. To write your name in binary, you convert each letter to its code, then write that number in 8-bit base-2. Capital and lowercase letters have different codes, so “A” and “a” look different in binary.
A worked example: “SAM”
S = 83 = 01010011, A = 65 = 01000001, M = 77 = 01001101. So “SAM” in binary is 01010011 01000001 01001101. Each character becomes a group of eight 0s and 1s, separated by spaces for readability.
The fast way
Doing this by hand is good practice, but a text-to-binary converter does it instantly for any name — handy for binary jewellery, tattoos, geeky gifts and posters. Paste your name, copy the binary, and double-check the spacing groups it into bytes.
FAQ
Why do uppercase and lowercase look different in binary?+
They have different ASCII codes — “A” is 65 (01000001) and “a” is 97 (01100001) — so their binary differs by one bit in the third position.
