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).

Examples

  • Hello, world → SGVsbG8sIHdvcmxk
  • café → Y2Fmw6k=
