FAQ

What is ASCII and how does it work?

ASCII (American Standard Code for Information Interchange) maps 128 characters to numbers 0-127. For example, 'A' = 65, 'a' = 97, '0' = 48. It is the foundation of text encoding in computing.

How do I convert text to ASCII codes?

Enter text in the input field and the tool shows the ASCII value for each character. Supports decimal, hexadecimal, octal, and binary representations. Non-ASCII characters use extended encodings like UTF-8.

What is the difference between ASCII and Unicode?

ASCII covers 128 characters (English letters, digits, symbols). Unicode covers 150,000+ characters from all writing systems worldwide. UTF-8, the most common Unicode encoding, is backwards-compatible with ASCII.
