Overview

The Core PDF API component of the HiQPdf Next Library for .NET provides a powerful API for programmatically creating, manipulating and securing PDF documents.

You can create PDF documents by adding text, images and other graphical elements and enhance them with advanced features such as encryption, permissions, digital signatures, custom headers, footers, stamps and other document processing options.

The library 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 Core runtimes and is ideal when developing on one operating system and deploying to multiple runtime environments.

If you need a single-platform package, you can use HiQPdf.Next.Core.Windows or HiQPdf.Next.Core.Linux.
