Text to Binary Converter

Type any text — a name, word, or sentence — and get binary instantly. Name to binary is the same tool: a name is just text. Each character becomes its code, then binary.

How to convert text to binary

1. Take one character. Take the first character, for example H in "Hi".
2. Find its code. Every character has a code: H is 72, i is 105, A is 65, space is 32.
3. Convert the code to binary. 72 = 1001000, 105 = 1101001, 65 = 1000001.
4. Join with spaces. Join the binary groups with spaces. "Hi" becomes "1001000 1101001".

Worked examples

"Hi" → "1001000 1101001". H is 72 = 1001000, i is 105 = 1101001.

"Ana" → "1000001 1101110 1100001". A is 65 = 1000001, n is 110 = 1101110, a is 97 = 1100001. This is the same name-to-binary conversion — just text to binary applied to a name.

Padding note: RadixFlip shows minimal binary with no leading zeros: A = 1000001. With 8-bit padding the same value is written 01000001. Both mean 65.

How to convert text to binary in code

Python

def text_to_binary(text):
    return " ".join(format(ord(c), "b") for c in text)

print(text_to_binary("Hi"))   # 1001000 1101001
print(text_to_binary("Ana"))  # 1000001 1101110 1100001
# 8-bit padded: " ".join(format(ord(c), "08b") for c in text)

Java

// Minimal binary, one group per character
String textToBinary(String text) {
    StringBuilder out = new StringBuilder();
    for (int i = 0; i < text.length(); i++) {
        if (i > 0) out.append(" ");
        out.append(Integer.toBinaryString(text.charAt(i)));
    }
    return out.toString();
}
// textToBinary("Hi") → "1001000 1101001"

C

#include <stdio.h>
#include <string.h>

void printBinary(int n) {
    if (n == 0) { printf("0"); return; }
    char bits[32]; int i = 0;
    while (n > 0) { bits[i++] = (n % 2) + '0'; n /= 2; }
    for (int j = i - 1; j >= 0; j--) putchar(bits[j]);
}

int main(void) {
    const char *text = "Hi";
    for (size_t i = 0; i < strlen(text); i++) {
        if (i > 0) putchar(' ');
        printBinary((unsigned char) text[i]);
    }
    // prints: 1001000 1101001
    return 0;
}

These snippets use the character code (ASCII for English letters, digits, and punctuation). RadixFlip uses Unicode code points, so emoji count as one character with one code.
