Select a character to inspect its codes.

How to use it

Search by a character, decimal code such as 65, hex code such as 0x41, or a name such as space. Select a character to inspect its codes and copy printable characters. Expanded adds binary, HTML entities and full descriptions.

Useful example

Uppercase A is decimal 65 and hex 41; lowercase a is decimal 97 and hex 61. The space character is decimal 32.

ASCII, Unicode and line endings

ASCII contains 128 codes, numbered 0–127. Unicode includes many more characters; UTF-8 preserves the ASCII byte values for that first range. LF is decimal 10 (hex 0A) and CR is decimal 13 (hex 0D). A Windows-style text line ending often uses CR followed by LF. Numeric HTML references for control codes are not a promise that browsers render those controls as visible characters.

Frequently asked questions

How do I find the code for A?

Search A or enter 0x41. Uppercase A is decimal 65, hexadecimal 41 and binary 01000001. Lowercase a is a different code: decimal 97.

Where are accented letters and emoji?

They are outside standard ASCII. An extended 8-bit code page is not interchangeable with Unicode. Use the binary translator for UTF-8 text.

Why can I not copy a visible character for NUL?

Control codes describe operations or separators rather than ordinary printable glyphs. The chart shows their names and values for reference.
