Base64 encoder / decoder

Handles UTF-8 text correctly, not just ASCII.

What is Base64 encoder / decoder?

Base64 represents arbitrary binary data as plain ASCII text, using only letters, digits, + and / — it's how images get embedded directly in CSS/HTML, and how email attachments and Basic Auth credentials are transmitted as text.

How to use it

Type plain text to encode it, or paste Base64 to decode it back. Correctly handles full UTF-8 text, not just ASCII.

Example

"Hello, ITcard!" -> SGVsbG8sIElUY2FyZCE=
