pe_to_shellcode is a research-oriented tool that converts a Windows Portable Executable into a form that can be loaded from memory like shellcode. The resulting file remains a valid PE while also being modified so execution can begin from the start of the buffer. The project supports both 32-bit and 64-bit PE files. Its goal is to add a reflective loading stub after compilation, instead of requiring the developer to build the PE with reflective loading already integrated. This makes it useful for controlled security research, malware analysis labs, and educational work on PE loading behavior. Because the technique is closely related to in-memory execution, it should be handled only in authorized environments.
