NReco.PdfGenerator
HTML to PDF converter for C#/.NET (WkHtmlToPdf wrapper). Generates pretty-looking PDF by HTML template or web page URL. Web page is rendered using QtWebKit engine and PDF result is very similar to a web browser view. Engine supports page header/footer, page numbering, custom fonts, javascript execution. NReco.PdfGenerator nuget can be used for free in non-SaaS apps that have only one single-server production deployment.
