What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding standard using 7 bits to represent 128 characters:

• 0–31: Control characters (non-printable)
• 32: Space
• 33–47: Punctuation & symbols
• 48–57: Digits 0-9
• 65–90: Uppercase A-Z
• 97–122: Lowercase a-z
• 127: DEL (delete)

About Text to ASCII Conversion

Why Convert to ASCII?

ASCII codes are fundamental in programming, data transmission, and computer science. Converting text to numeric codes helps with debugging, encoding, protocol analysis, and understanding how computers store text.

Number Bases

Decimal (base-10) is human-readable. Hexadecimal (base-16) is compact and common in programming. Binary (base-2) shows actual bit patterns. Octal (base-8) was used in early computing.

Extended ASCII & Unicode

Standard ASCII covers 0–127 (7-bit). Extended ASCII uses 128–255 (8-bit). Unicode extends far beyond, covering emojis, CJK characters, and more — this tool handles the full Unicode range.

Common Values

'A' = 65, 'a' = 97, '0' = 48, Space = 32, Newline = 10. The difference between uppercase and lowercase is always 32 — a classic computer science trick.
