What is ASCII?

ASCII stands for American Standard Code for Information Interchange. It's the foundational character encoding standard used in computers worldwide since 1963. Each character—whether it's a letter, number, symbol, or space—gets assigned a unique number from 0 to 127 (standard ASCII) or up to 255 (extended ASCII). This numeric system lets computers store and transmit text reliably.

Understanding ASCII codes matters if you're into programming, web development, data processing, or cybersecurity. When your code needs to validate user input, manipulate strings, or work with binary data, you often need to know the ASCII value of characters. For instance, checking if a character is uppercase or lowercase involves comparing ASCII ranges.

Modern systems use extensions like UTF-8 that include ASCII, supporting thousands of characters beyond English. But ASCII remains the backbone—every text file, email, and web page uses it. Our converter helps you quickly look up any character's ASCII representation in multiple formats useful for different technical contexts.
