What this cannot tell you
- Covers standard 7-bit ASCII (0–127). Characters beyond that are Unicode, handled by other tools.
How this calculation works
Enter a single character, a decimal code or a hex code, and the tool shows that character’s value in every common base plus its name if it is a control character.
What the results mean
- Control characters
- Codes 0–31 and 127 have no printable glyph — they signal formatting like tab (9) and newline (10).
- Printable range
- Codes 33–126 are the visible characters: letters, digits and punctuation.
Frequently asked questions
What is the difference between ASCII and Unicode?
ASCII is the original 7-bit set of 128 characters covering English letters, digits and basic punctuation. Unicode is the vast superset that adds every other script, emoji and symbol — and its first 128 code points are identical to ASCII, which is why ASCII text is always valid Unicode.
