What is the ASCII code for common characters?

Space=32, A=65, a=97, 0=48, newline=10, tab=9. The uppercase alphabet runs from 65 (A) to 90 (Z). Lowercase from 97 (a) to 122 (z). Digits from 48 (0) to 57 (9).

What is the difference between ASCII and Unicode?

ASCII covers 128 characters (English letters, digits, basic punctuation). Unicode covers 143,000+ characters covering all human writing systems and emoji. UTF-8 encoding is backward-compatible with ASCII for the first 128 code points.

What are control characters in ASCII?

Control characters (codes 0–31 and 127) are non-printable characters for controlling devices and text formatting: LF (10) is a newline, CR (13) is a carriage return, ESC (27) is the escape key, DEL (127) deletes.

What is ASCII Converter?

ASCII (American Standard Code for Information Interchange) maps 128 characters — letters, digits, punctuation, and control characters — to numeric codes from 0 to 127. Understanding ASCII is fundamental to text encoding, binary data processing, and low-level programming. DailyDevTools' ASCII Converter converts text to ASCII codes (decimal, hex, binary, octal) and back, supporting both ASCII and Unicode code points.

How to use ASCII Converter

1Type or paste text to convert it to ASCII decimal codes (space-separated or one per line)
2Or paste a list of ASCII decimal codes to convert back to text
3Toggle between decimal, hexadecimal, binary, and octal output formats
4Use the Unicode mode to go beyond ASCII and convert any character to its Unicode code point
