Character Code Converter

Convert text between ASCII, decimal, hex, octal, binary, Unicode, and HTML entities.

Convert text and characters between ASCII/Unicode, Decimal, Hexadecimal, Octal, Binary, Unicode notation (such as U+0041), and HTML numeric entities in decimal (A) or hex (A). Type into any field and the rest update live. Each field works per Unicode code point, so characters beyond the basic ASCII range convert correctly. Go to the UTF-8 tool to convert UTF-8 byte sequences. Go to the Base Conversion tool to convert bases from 2 to 62.
