QuestPDF
QuestPDF is an open-source .NET library for generating PDF documents programmatically in C#. It uses a fluent API and a layout engine inspired by web technologies like CSS Flexbox to create complex, high-performance PDFs without external dependencies. It is designed to be fast, memory-efficient, and easy to integrate into .NET applications.
Developers should use QuestPDF when building .NET applications that require dynamic PDF generation, such as invoices, reports, or documents with complex layouts. It is ideal for scenarios where performance and low memory usage are critical, as it avoids heavy external tools like iTextSharp or paid libraries. Its declarative API simplifies creating responsive and structured PDFs compared to low-level approaches.
