About UTF-8 Encoding
UTF-8 is a variable-width character encoding that uses 1-4 bytes per character. ASCII characters (0-127) use 1 byte, while extended characters use more bytes. This tool converts text to/from UTF-8 byte sequences in decimal, hexadecimal, or binary format.
What is UTF-8 Encoding?
UTF-8 is a variable-width character encoding that can represent every character in the Unicode standard using 1 to 4 bytes.
It's the dominant encoding for the web and is backward compatible with ASCII. UTF-8 efficiently handles both simple English text and complex international characters.
