Text to Binary
Convert text to binary (0s and 1s) — each character as its 8-bit binary representation.
About Text to Binary
Converting text to binary displays the raw bit-level representation of each character. Each character is converted to its ASCII/UTF-8 byte value, then expressed as an 8-bit binary number. The letter 'H' is ASCII 72 = 01001000 in binary. 'i' is ASCII 105 = 01101001. Together "Hi" = 01001000 01101001.
Understanding binary representation is foundational for computer science students, programmers working with low-level systems, network engineers analyzing packet data, and anyone learning how computers store and process text data at the byte level.
FAQ
Why are there always 8 digits per character?
Each character is represented as one byte (8 bits) for ASCII characters. A byte can store values 0–255. The 8 bits are padded with leading zeros to always show the full 8 bits — so the number 1 is shown as 00000001, not just 1.
How do I convert binary back to text?
Use the Binary Converter tool which supports the reverse conversion. Group the binary digits into 8-bit chunks, convert each to a decimal number, then look up that ASCII/Unicode character.
