它的主要功能可以被分為3個主要部分：PDF的創建，PDF的編輯和PDF格式的填充。此庫對標準.NET框架和壓縮的.NET框架都提供支持。由于PDF4NET的發布是免費的，因此當用PDF4NET進行開發時，工程的花費將會減少。 PDF4NET是一種.NET庫，它能夠對運行中的任意.NET應用程序生成和插入pdf文檔。這個庫不依賴于任何Adobe產品來創建和插入pdf文件。它通過一個簡單的對象模塊把pdf文件復雜的結構隱藏起來，這個對象模塊允許開發者創建復雜的pdf文件或者用幾行代碼來插入已有的pdf文件。PDF4NET庫從屬于GDI+模型，因此減少了學習的時間，提高了工作效率。它使用了基于網格的圖層方法，在文檔頁面中這種圖層方法允許內容的精確定位。最終確定的pdf文件被壓縮以使得該庫能夠適用于Web應用程序。PDF4NET庫能夠從WinForms and WebForms (ASP.NET)應用程序中直接使用而不受任何限制。同時，相同的包包括了該庫的壓縮.NET框架(Compact .NET Framework)版本。這個庫是完全用C#來實現的,能被完全操縱。 PDF4NET庫可以提供給每個開發者，而且它的發行是免費的，這樣就降低了開發者的工程開銷。
