Overview

HiQPdf Next HTML to PDF Converter for .NET is a core component of the HiQPdf Next Library for .NET, using an advanced, highly accurate and reliable Chromium-based rendering engine to process modern and complex HTML, CSS and JavaScript content in compliance with the latest standards.

The converter targets .NET Standard 2.0 and can be used in .NET Core and .NET Framework applications deployed on Windows and Linux platforms, including Azure App Service, Azure Functions and Docker.

This is a multi-platform metapackage that references both the Windows x64 and Linux x64 HiQPdf Next HTML to PDF runtimes.

On Windows platforms, the runtime generally does not require additional dependencies. On Linux platforms, installing some dependency packages might be required, depending on the Linux distribution and version, as described in the online documentation.
