Base64 Encoder
Encode UTF-8 text to Base64 in your browser.
Tool workspace
Encodes UTF-8 text to Base64 in your browser. Unicode is encoded as UTF-8 bytes before Base64.
How it works
Paste text and Encode. The tool converts UTF-8 bytes to standard Base64 in your browser.
Empty input clears the result—no error. Unicode characters are encoded as UTF-8 before Base64 (not Latin-1).
