Text to Binary Conversion
Every character in text has a numeric code point. Binary conversion represents that code point in base 2. For ASCII text, each character is one 8-bit byte; for UTF-8 text, characters may use 1–4 bytes.
How It Works
- Each character maps to an ASCII or Unicode code point (decimal number)
- That decimal is converted to 8-bit binary for ASCII characters
- Example: 'H' → decimal 72 → binary
01001000 - Example: 'i' → decimal 105 → binary
01101001 - Bytes are typically separated by spaces for readability
ASCII Code Points Reference
- Space = 32 =
00100000 - A–Z = 65–90 (uppercase letters)
- a–z = 97–122 (lowercase letters)
- 0–9 = 48–57 (digit characters)
- Lowercase = uppercase + 32 (bit 5 difference)
What is the difference between ASCII and Unicode binary?
ASCII uses 7 bits per character and covers only 128 characters (English letters, digits, basic punctuation). Unicode supports over 1 million characters for all world scripts. UTF-8 encoding represents Unicode characters using 1–4 bytes — the first 128 code points are identical to ASCII, stored as single bytes.
How do I read binary-encoded text?
Split by spaces to get individual bytes. Convert each 8-bit binary group to decimal (each bit is a power of 2 from right to left). Look up the decimal in an ASCII table. For example: 01001000 = 64+8 = 72 = 'H'; 01101001 = 64+32+8+1 = 105 = 'i'. Together they spell "Hi".
Is binary text the same as machine code?
No — binary text encoding is a human-readable representation of character codes. Machine code is actual CPU instructions — sequences of bytes that the processor executes directly. The binary patterns for CPU instructions (opcodes, operands) have no relation to text character codes.
