Content that has been base 64 encoded is not permanently changed. The process of converting it back to the standard text it was originally is actually very simple. Executing a base 64 decode will allow you to convert a string back to a standard piece of text…assuming of course the original content was standard readable text.
The tool below will allow you to decode a base 64 string. Enter the text into the box and click the button to decode. The decoded value will appear in the box below.
