What would you like to do?
Windows jscript base64 encoder. Drag and drop files you wanna encode to this .js file.
var fsDoOverwrite = true // Overwrite file with base64 code
var fsAsASCII = false // Create base64 code file as ASCII file
var adTypeBinary = 1 // Binary file is encoded
function encode(from, to) {
var inputStream = WScript.CreateObject("ADODB.Stream");
inputStream.Type = adTypeBinary
var xml = WScript.CreateObject("MSXml2.DOMDocument");
var element = xml.createElement("Base64Data");
element.dataType = "bin.base64";
element.nodeTypedValue = inputStream.Read();
var fileSystem = WScript.CreateObject("Scripting.FileSystemObject");
var outputStream = fileSystem.CreateTextFile(to, fsDoOverwrite, fsAsASCII);
outputStream.Write(element.text.replace(/\n/g, ""));
function getTxtName(name) {
return name + ".txt";
function main() {
var args = WScript.Arguments;
for(i = 0; i < args.length; ++i) {
encode(args(i), getTxtName(args(i)));
