Where can I find a string to bytes32 converter online?

Question

So far I am using this solidity code

pragma solidity 0.4.24;

contract Converter{
    function Converter(){

    }

    function stringToBytes32(string memory source) returns (bytes32 result) {
        bytes memory tempEmptyStringTest = bytes(source);
        if (tempEmptyStringTest.length == 0) {
            return 0x0;
        }

        assembly {
            result := mload(add(source, 32))
        }
    }
}

Is there a website or online tool to easily convert strings to bytes32?
