We have found 2 software records in our database eligible for .docm to .pwd file format conversion.
Not many programs nowadays support the old Pocket Word document files (.pwd) so it will be very tricky to produce it - for whatever reason someone needs it. One of such program that supposedly still can save to pwd format is TextMaker, which (if possible) is pretty much the only way to achieve docm to pwd conversion, aka Word to PocketWord.

TextMaker is also licensed to other office suites, such as Ashampoo Office.
Word Mobile does not fully support all features included in Microsoft Word for desktop computers. However you will be still able to open the documents on your found phone, but the unsupported content won't be visible.
