Encode/Decode text with just a click. If you want to encode the text to Base64 by default, select Encode level to Default. There are 5 levels of encode/decode, if you select 3, the text will be encoded three times. To decode, you'll have to select decode level to 3 to get the original string. Always remember the level you selected when encoding. If you don't want to use encode/decode level, just select or set the level to Default.
