Text to Binary Converter - Encode Text as Binary Code

Text is stored on computers as binary numbers. Each character maps to a number (ASCII code or Unicode code point), and that number is represented in binary (base-2, using only 0 and 1). Our tool lets you see and generate this binary representation.

How Text to Binary Works

1. Each character is converted to its ASCII/UTF-8 code point (a number)
2. That number is converted to binary (base-2 representation)
3. Binary is padded to 8 bits (1 byte) per character
4. Example: A = ASCII 65 = binary 01000001

ASCII vs UTF-8 in Binary

ASCII characters (English letters, digits, basic symbols) fit in 7 bits (1 byte). UTF-8 uses 1-4 bytes per character, so non-ASCII characters (Chinese, emoji, accented letters) produce longer binary strings.
