How do you change rar to exe?

To change a RAR file to an EXE file, you can rename the file extension from .rar to .exe. However, this does not convert the file format; it merely changes its label, and the file will remain a compressed archive. If you need to extract files from a RAR archive and then create an EXE, you should first extract the contents using a program like WinRAR, then use a tool like a self-extracting archive creator to package the files into an EXE format. Always be cautious with EXE files, as they can contain harmful software.
