The ASCII Table Reference shows all 128 standard ASCII characters (codes 0–127). ASCII (American Standard Code for Information Interchange) is the foundation of digital text encoding. Each character is assigned a unique 7-bit binary number, displayed here in decimal, hexadecimal, and binary formats.
Characters 0–31 are control codes (non-printable), 32–126 are printable (space through tilde), and 127 is the DEL control character. Common characters like space (32), tab (9), and line feed (10) are highlighted in blue. Also check out our Binary to Text Converter and Hex Converter for related encoding utilities.
