Base64 Decode and Encode Online

Base64 is an encoding format based on 64 characters chosen for being the most compatible with all other systems.
You have to use base64 encoding whenever you want to transmit data from a language to another language. Or when you want to forward special parameters where encoding requires reliable and rigorous compatibility.
If your code is being transfered from PHP to JavaScript, you should better use JSON format.
