The complete ASCII table

ASCII (American Standard Code for Information Interchange) maps the numbers 0–127 to characters: control codes, punctuation, digits and the basic Latin letters. This table lists every code in decimal, hexadecimal, octal and binary, along with the printable character or the control-code abbreviation. Everything runs in your browser — nothing is sent anywhere.

Control codes vs printable characters

Codes 0–31 and 127 are non-printing control characters such as NUL, tab (HT), line feed (LF) and carriage return (CR). Codes 32–126 are printable, starting with the space (32) and ending with the tilde (126). Use the search box to find a character by its number, hex value, glyph or name.

FAQ

What is the ASCII code for "A"? The capital letter A is decimal 65, hex 0x41, octal 101 and binary 01000001. Lowercase "a" is decimal 97.

How do I convert ASCII to hex? Find the character's decimal value and read the hex column, or type the character into the search box — its hex code is shown alongside.

Is ASCII the same as Unicode? The first 128 Unicode code points are identical to ASCII, so ASCII is effectively a subset of Unicode (and of UTF-8).

What is the DEL character? Decimal 127 (DEL) is a control code originally used to delete characters on paper tape; it is not the same as the Backspace key (decimal 8).
