Documents prepared by MS Office apps can be saved directly as PDF files in addition to their ‘native’ format such as .doc or .xls.
You should also be aware that there are inexpensive easily obtained online services that will revert a PDF document back to it’s original format. I use these services frequently.
Simply scanning or saving a document into PDF format is no guarantee that it can’t be altered. It may be possible that security can be inserted if you the full ADOBE version to create PDF. I can’t afford to purchase the full ADOBE version, so I can’t say for sure. So you should be careful. Scanning into one of the popular picture formats such as JPEG might be more secure – of course the trade off is in increased storage requirements.
