Online Binary Encoder & Decoder

A binary code represents text or computer processor instructions using the binary number system's two binary digits, 0 and 1. The binary code assigns a bit string to each symbol or instruction. For example, a binary string of eight binary digits (bits) can represent any of 256 possible values and can therefore correspond to a variety of different symbols, letters or instructions. (source wikipedia)
Scripts are in pure javascript to prevent encoded/decoded Binary storing which could be seen by server administrator.

copy to clipboard JS Binary encode/decode function
//Binary decode to string
result = '';
for( i=0 ; i < binaryString.length ; i=i+8 )
	result += String.fromCharCode(parseInt(binaryString.substring(i,i+8), 2) );

//Binary decode to decimal
result = parseInt(binaryString,2);

//Binary decode to hexadecimal
result = parseInt(binaryString,8);

//Binary encode
for (i=0; i < string.length; i++)
    result +=string[i].charCodeAt(0).toString(2);

Binary decimal convertion:
53 =        1  1 0 1 0 1
256 128 64 32 16 8 4 2 1
