But .PDF documents can! We are guessing that since some file formats are proprietary, there was less risk of legal headaches by using PDF, since Adobe.com released the file specifications into the public domain a few years ago. Also PDF has become an internet standard file format.
So the question becomes, how can our patrons convert word processor (or other) documents to PDF so they can be uploaded to Memories?
A word processor (or other) document can usually be "saved" or "printed" or "exported" as a PDF document. This is a built-in feature of recent computer operating systems, such as Windows 10.
(When printing, select Microsoft Print to PDF as the printer, to create a PDF version of the document.) Easy-peasy.
What about patrons with older computers and older software?
In this situation, they can choose to download one of the free PDF writers from the internet such as CutePDF or PrimoPDF. There are probably a dozen to choose from. We assume no responsibility for their use, of course. Once installed, it appears as a new printer that can be chosen. Anything "printed" to the PDF writer creates a perfect PDF copy of itself.
A 15 MB PDF document can be 100 pages or more in length. The fewer photos involved, the more pages will fit within the 15 MB limit.
