What converts cleanly and what needs a look
PDF to Word works best on documents that were born digital, where the text is real characters rather than a scanned picture. Straightforward reports, letters and articles with a single column come across almost perfectly, with paragraphs, headings, lists and simple tables rebuilt as editable Word objects and images dropped into position. Heavily designed pages, tightly packed multi-column layouts and complex nested tables are the ones to inspect after converting, since they may need a few manual tweaks. Knowing this in advance saves time: convert, then skim for the handful of spots where a busy layout shifted.
