UTF-8 (8-bit Unicode Transformation Format) is a variable length character encoding that can encode any of the valid Unicode characters. Each Unicode character is encoded using 1-4 bytes. Standard 7-bit ASCII characters are always encoded as a single byte in UTF-8, making the UTF-8 encoding backwards compatible with ASCII. UTF-8 is the most common Unicode encoding and used by a majority of applications and websites.

To convert to other formats, go to the ASCII, Decimal, Binary, Hex, and Octal tool.
