ASCII Table

Browse all 128 standard ASCII characters with detailed information.

ASCII (American Standard Code for Information Interchange) is a character encoding standard that uses 7 bits to represent 128 unique characters. It includes control characters (0-31), printable characters like letters, numbers, and symbols (32-126), and the delete character (127). This standardized encoding forms the foundation of modern computing text representation.
