Decode On Copy tries to base64 decode any text that you copy, and if it can be decoded to a valid URL, the URL will be copied to your clipboard instead. It is best demonstrated by example.
- The simplest case is where you copy something that is not an encoded URL, like
http://www.example.com
. Since the text you copied can't be decoded to a valid URL, you will end up withhttp://www.example.com
on your clipboard. - Now, if you copy
aHR0cDovL3d3dy5leGFtcGxlLmNvbQ==
, Decode On Copy will notice that it can be base64 decoded tohttp://www.example.com
and will copyhttp://www.example.com
to your clipboard instead ofaHR0cDovL3d3dy5leGFtcGxlLmNvbQ==
. - Decode On Copy can also detect URLs that have been base64 encoded multiple times. So copying

would also result inhttp://www.example.com
being copied to your clipboard.
