How It Works

Base64 maps every 6 bits of binary data onto a printable character (A-Z, a-z, 0-9, +, /). Encoded output is typically about 33% larger, and is commonly used to carry images or binary files over HTTP.

Privacy & Security

Every conversion runs locally in your browser (JavaScript). Nothing is uploaded to a server, so sensitive data stays with you.
