!!! Latest Update: Right now you can choose multiple files (docx) and convert all of them to pdf format.
Input word doc, output pdf file
Download those 5 .rar files and extract all to your preferred location, (That is, select all those 5, and extract) Then get into dist folder and double-click (execute) WordToPdf.exe
Select one (currently version supported) .docx file and select the location you wanna save the pdf file. Then click convert.
Or If you have python installed, just run wordToPdf.py.
Note: You need pip install docx2pdf
(Future update plan, use multiprocess to convert multiple .docx to pdf)
