What does Text to ASCII Converter do?

Convert text to character codes — decimal, hexadecimal, octal or binary — and back again. Works with the full Unicode range, so it handles far more than the original 128 ASCII characters.

Frequently Asked Questions

What is ASCII?

A 7-bit character encoding defining 128 characters — the English alphabet, digits, punctuation and control codes. Unicode superseded it but kept the first 128 code points identical, so ASCII is still a valid subset.

What is the ASCII code for A?

65 in decimal, 41 in hex, 101 in octal and 01000001 in binary. Lowercase "a" is 97 — exactly 32 higher, which is why case conversion is a single bit flip.

What happens with emoji and non-English characters?

They have no ASCII code, so the tool shows their Unicode code point instead. An emoji typically sits above U+1F300, far outside the ASCII range.

What is the difference between a code point and a byte?

A code point identifies a character; bytes are how it is stored. U+00E9 (é) is one code point but two bytes in UTF-8. This tool shows code points — use the binary converter for bytes.
