Convert API is a powerful REST API that helped us easily convert all our documents from word to PDF.

DOCX to PDF with formatting fidelity
We were looking for a solution that converts DOCX files to PDF generated by our nodejs system. Of the various platforms tested, ConvertApi was one of the few that maintained the document's fidelity, although the generated file is excessively large, therefore, only 4 stars.
