Combine HTML to PDF using C# REST API

Easily merge HTML to PDF format in C# code. This C# library is designed to combine multiple HTML files into a single PDF file using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native HTML to PDF merging solution that provides C# programmers with both great development flexibility and powerful features. Joining HTML files together is often used when it is necessary to create a set of PDF documents of the same structure, each of which contains unique data. By merging files, you can automate your digital HTML/PDF workflows and offload some routine parts of the process to fast and efficient document-processing C# software.
