Bin2Au3

Bin2Au3 is a small-sized and portable piece of software that gives you the possibility to convert binary files into AutoIt format, which is an automation language for Windows. It contains a couple of intuitive options.

Doesn't need installation

Since installation isn't required, you can copy the downloaded executable file to any preferred directory on the computer and just double-click it to bring up the main window and configure settings.
Otherwise, you can keep Bin2Au3 stored on a USB flash drive and directly run it on any machine without having to set up anything. It doesn't add new entries to the system registry or create extra files on the disk without your permission.

Set the source binary file and output options

The main window doesn't put emphasis on graphical elements, preferring to focus on functionality instead. You can use the built-in file browser to indicate the source file and the output directory and name for the AU3-formatted file.
Moreover, it's possible to set the variable name and way to name it as, add #include-once, and show tooltips. The new file can be then generated with the click of a button. Otherwise, you can reset all options to default if you change your mind.
Although Bin2Au3 hasn't received updates for a very long time, we didn't have any trouble getting it to work on Windows 10 in our tests. It carried out conversion operations fast while remaining light on system resources consumption.

Simple binary-to-AutoIt conversion tool

All things considered, Bin2Au3 may not have a rich range of options and configuration settings to offer, but it provides you with a fast and straightforward method of producing AutoIt files from binary format with minimum effort on your behalf. Too bad that it doesn't give you the possibility to preview results so you can make adjustments before triggering the conversion operation.
