Yes, Convertify supports batch processing with the Basic and Pro versions. You can convert hundreds or thousands of DOCX files simultaneously, maintaining individual file names and folder structures for easy organization.
Do I need Microsoft Word installed to convert DOCX files?

Yes, all text content from your DOCX files remains fully searchable in the resulting PDF. The conversion preserves text layers, making it easy to find specific content using PDF search functions.
Can I convert DOCX files with track changes and comments?
