ASCII Table & Character Codes

ASCII reference plus text ⇄ codes in many formats

How it works

Three modes: a searchable ASCII table (0–127 or 0–255) showing each character's decimal, hex, octal, binary, HTML entity and control-code name; an Encode mode that converts text to per-character codes in your chosen format and separator; and a Decode mode that turns codes back into text. Useful for debugging encodings, building escape sequences and learning the ASCII set.

Frequently asked

What representations does it show?

For every character: decimal, hexadecimal, octal, 8-bit binary, HTML numeric entity, and (for control characters) the standard name like NUL, TAB, LF or DEL.

Can it convert text to ASCII codes and back?

Yes. Encode mode turns text into codes (decimal, hex, octal, binary, HTML entity or \x/\u escapes); Decode mode reconstructs the original text from codes.
