Character codes made easy
Each character has a number: “A” is 65, “a” is 97, a space is 32. This converter lists those codes for any text, in decimal, hexadecimal, binary or octal, ready to copy into code, spreadsheets or homework.
ASCII covers the 128 basic English characters. For anything beyond — é, ₹, emoji, Hindi — the tool shows the character's Unicode code point, the modern extension of ASCII.

- For the actual bytes stored in a file, use Text to Binary, which shows UTF-8 bytes.
Frequently asked questions
What is the ASCII code of A?
65 in decimal, 41 in hexadecimal and 01000001 in binary.
What happens to emoji?
They're outside ASCII, so the tool shows their Unicode code point, for example 128075 for 👋.
Is ASCII the same as Unicode?
The first 128 Unicode code points are exactly ASCII. Unicode extends the list to over a million characters.
