Hex to Base64 Converter

Convert hexadecimal bytes

Convert hexadecimal byte pairs to Base64, or decode Base64 to hex without changing the binary data.

Example

UTF-8 text Hello becomes SGVsbG8=. Decoding reverses the operation. Binary data may not be readable text; download it using the files tool.

Base64 represents each three bytes as four characters, increasing size by roughly one third. Normalization preserves bytes; it cannot recover corrupted or missing data.

Text forms work without JavaScript. File conversion happens locally in your browser. Text submitted for conversion is processed on the server and is not stored.

Specification: RFC 4648.
