info About Base64 Decoder

Base64 Decoder is a tool to transform encoded text in base64 form to normal character / string in original character. This tool is opposite of the Base64 Encoder which workes by reversing the function of Base64 Encoder.

Base64 encoding usually used when binary data need to be encoded. Encoded data will stored and transfered over media that design to deal with textual information. This guarantees that the data won't changed during transfer without modification. Base64 encode generally in some application like electronic mail via MIME.

MIME which stands for MUlti-porpose Internet Mail Extensions is one of application used base64 encode format to transfer data. It is used to transmit data with file attachment over Simple Mail Transfer Protocol. Encoding data in base64 will encrease more 33% the data space than the original data.

Base64 will turn the binary data in to text. The encoded data will get the character in range A-Z, a-z, and 0-9 for the initial 62 values that can use to encode data. Other base64 variation share the same property but they use different symbols in the last two values.

For Example, The encoded text is :

And the decoded text as result is :
