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.

One of the best in the market
I'm from a software company that provides services for other companies. We were having trouble with an API that converts some documents. When we discovered ConvertAPI it was a blessing. The conversion keeps the document 100% as the original and the API is fast and 24/7 avaiable. We have a decent amount of daily requests and in the 9 months we are with them the service never let us down.

API is the the best!
This application especially to their PDF converting feature is of a high quality service. The image that you will convert into PDF format will not be blurred and will maintain to its original pixel. Furthermore, it can convert files with large amount of bits unlike other online converter which is restricted only to 10mb for your file.

The best API for this task
The best API for this task, all over internet. My pain was to convert encrypted pdf documents to plain text. They're constantly improving their already good converter. Their GUI to generate requests and code snippets is excellent as well. I totally recommend!

They are successful according to over two years of our experiences
We have been using ConvertAPI for over two years. During this time, we have converted over 100,000 documents via this service. We successfully convert all the documents that our company needs via ConvertAPI. We find the API very successful and fast. It performs invoicing and other financial services successfully with a credit card at acceptable pricing. We are happy that our support requests mostly respond on the same day.
