Convert EXE to PDF

In most cases, exe to pdf conversion is searched by users who think their .exe file contains a PDF document, and they are looking for ways how to recover the files. PDF files are not commonly distributed as executables, mainly due to security reasons; on the other hand, it's not something that is hard to achieve.

You can find many (often dubious) utilities that offer tools for making .exe files from PDF files for the purpose of being able to view the document without the need for a viewer. But this brings the risk of infecting the .exe wrapper with viruses, trojans, or some kind of malware.

Some e-books or other documents that are downloaded through P2P networks are sometimes distributed as .exe files, but these are just SFX archives. Although self-extracting (.exe) files are mostly harmless, any .exe file downloaded from the internet is very suspicious and might contain a virus, trojan, or other kind of harmful script or code. Unless you know exactly what you are doing, do not execute unknown .exe files and first check them out with some antivirus.

Recovery of PDF documents from EXE files

In case of SFX archives, you can simply decompress the files and get the PDF documents, but to make sure it's safe you should first check out the archive with some antivirus software.

If your .exe file is actually EXE wrapper that contains PDF document, the things might be much more difficult, especially if you are unsure about the origin of your .exe file. Determining the origin of your file is your best option here and it's not really something we can help you with. Some utilities that offer PDFtoEXE conversion often offer the reverse as well. Some DRM protected ebooks might be designed to prevent such recovery in first place, and there is probably no way around this.

Last option would be in the use of PDF recovery tools. If your .exe files contains PDF document, these tools might be just what you need.

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