Jongware, at the bottom of the page you linked to it says:
“With this functionality, you can transform your PDFs back into fully editable Word documents, rehydrating headings, bulleted/numbered lists, tables, footnotes, etc. by analyzing the contents of the PDF file.” The goal is not to make Word into a PDF reader or PDF editor. The goal is to help you to bring the contents of PDF files back into an editable format using Word 2013.
It sounds like it is using a PDF to Word convert to extract elements and placing them in a new Word doc so people can edit them and then, I assume, make a new PDF.
Has anyone used a PDF to Word converter?
I'm assuming this will work best with rather simple PDFs. Of course we can look forward to the black text being converted into rich black text that we will have to then correct before sending to print. I shudder to think what else might be changed with PDF elements with this" workflow".
And the comments from secretaries "What do you mean, you can't edit my PDF? I can edit it in MS Word!" grrr...
There is absolutely no way that any Microsoft application program would be able to fully edit any arbitrary PDF content.
The Microsoft imaging model is a tiny subset of that of PDF. For example, PDF supports 16 different transparency blend modes and Microsoft supports only one (the normal mode - even drop shadows with Microsoft are different, Adobe drop shadows are done via the multiply blend mode which Microsoft doesn't support). What is Microsoft going to do with gradients that it doesn't support or color modes that it doesn't support? What you get with such PDF editing or conversion is an approximation of the PDF content.
Be forewarned! (By the way, this is exactly why Illustrator and InDesign don't claim to be PDF editors. They don't support the absolute complete PDF imaging model and they support a hell of a lot more of that imaging model than Microsoft does in its Office products.)
