Some people didn't have microsoft office installed (or did not buy them) but file conversion forced to use microsoft office only to convert document files to pdf. Although, other apps like wps office and libreoffice have the feature to export those files as pdf

Describe the solution you'd like
Add feature where you can use third party app other than microsoft office to convert document files into pdf or vice versa

Describe alternatives you've considered
In example, trying to convert .docx to .pdf using wps office will open up a conversion menu.
