Convert ISO to EXE

There is no way how you can actually convert iso to exe, i.e.  ISO disk image (.iso) to Windows Executable format (.exe). Nevertheless, there are some procedures that achieve something similar, although it is not the actual iso to exe export per se.

Launching executable from ISO disk images

Some users just want to launch some executable from the ISO and wonder what is the best way how to do this. You can simply mount the disk image in Windows and explore the contents through file manager. Any programs can be started from ISO, but be extra careful when handling executables from unknown or dubious sources.

Packaging ISO disk images as self-extracting archives

Another way how to achieve iso to exe conversion, is to compress it via some file archiver utility to a self-extracting archive, that also has EXE. Executing that archive would decompress the ISO. This can be done in programs like WinRAR, 7-zip or similar file archiver.

Simply put, it is impossible to convert ISO to EXE directly.
Thus, there is no so-called iso to exe converter or a free online .iso to .exe converter to be found.
