Export word document with high resolution PNG to PDF

Any easier solution might be to forego the in-built pdf conversion and use a pdf printer (I use pdfcreator) You'll likely find finer grained control (including DPI settings of the printout - start w/ 600x600 but it supports up to 2400x2400 iirc).

This may be an easier solution as it won't force you to reformat existing docs. It's also free.

As discussed in comments, at some point pdfcreator was engaged in installing some unwanted software along with their package. I believe they have since stopped this practice but to ensure you do not ever have to deal with or think about this I suggest using Ninite to install. Ninite's installer will strip out all the BS (if any) and install silently for you, which is nice. You can also re-run the ninite installer any time to update the software, again without any BS. Just in case.

EDIT - as per ThomasK this printing will not preserve hyperlinks in your output PDF. (I assume they will print, just not be clickable)

If you are using Windows 10 then you are lucky: you don’t need any third party PDF printer. Windows 10 comes with a PDF printer called Microsoft PDF Printer that you can make use of. I tried and it printed with decent resolution.

If running on Windows 8.1 or below, or requiring more functionality/better quality, JoelAZ’s answer is better. Just pay attention to where you download.

None of the aforementioned solutions worked for me including enabling the "do not compress images in file" and "select ISO 19005-1 complaint" options. It did not matter if I saved-as a PDF or exported as a PDF.

What DID work for me, was to create the PDF using the MS Office Microsoft Print to PDF printer option.

• Select Print from the File Options menu.
• Select Microsoft Print to PDF from the Printer drop down menu.
• Print. Specify where you want the PDF file to be created.
