Text ? Binary Converter

Each character is converted to its Unicode code point (a number), which is then represented as an 8-bit binary number padded with leading zeros. For example, 'A' (code 65) becomes 01000001.

The converter works with all Unicode characters, including emoji, CJK characters, and accented letters. For characters above code 255, the binary representation will be longer than 8 bits to accommodate the full code point.

Each character is converted to its ASCII or Unicode code point, then that number is represented in base-2 (binary). For example, 'A' is ASCII 65, which is 01000001 in 8-bit binary. UTF-8 characters may use multiple bytes, each represented as 8-bit binary.

ASCII uses 7 or 8 bits per character covering 128 basic characters. Unicode extends this to millions of characters using variable-length encodings like UTF-8 (1-4 bytes per character). This tool represents each character as 8-bit binary using its UTF-16 code point.

Binary representation is fundamental to understanding how computers store and transmit text. It's useful for education, debugging encoding issues, low-level programming, data forensics, and understanding bitwise operations in programming.

In the text-to-binary direction, output bytes are separated by spaces. When converting back, the tool splits on any whitespace, so you can paste binary with spaces, tabs, or newlines as separators.
