Files with the .DOCX extension contain formatted text documents, possibly with graphic elements, stored in a native format of Microsoft Word, since its 2017 version. DOCX files are an element of Office Open XML format specification.
Files with the PUB extension are document files, created and supported by the Microsoft Publisher program, and one of the Microsoft Office suite programs. PUB are multimedia files, containing text, raster and vector images, diagrams, charts, metadata, etc..
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the DOCX file after converting to PUB may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from DOCX to PUB to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting DOCX to PUB does not meet your expectations, you can simply try to find on the Internet a different version of your file in DOCX format, properly converted to a PUB file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file DOCX the desired result was not achieved, you can try to change the format of DOCX file to other than PUB. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your DOCX file converted by someone else, and the attempt to convert it to PUB on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the DOCX file in its original format (without conversion to PUB file). Such a solution will be difficult to implement, but it certainly will give the best result.
