About ASCII Table

ASCII (American Standard Code for Information Interchange) defines 128 characters numbered 0 through 127. Each row in the table above shows every representation of a character: decimal, octal, hexadecimal, 8-bit binary, the rendered symbol (or control code abbreviation), HTML numeric entity, and a human-readable description.

0–31 & 127 — Control characters for terminals, printers, and communication protocols. 32–126 — Printable characters: space, punctuation, digits, uppercase and lowercase letters.

Click any row to expand a detail panel with copyable values including Unicode code point and escape sequence. Use the search bar to filter the table by any field.
