QuestPDF
QuestPDF is a modern, open-source .NET library for generating PDF documents programmatically. It uses a fluent API and a layout engine inspired by web technologies (like CSS Flexbox) to create complex, high-quality PDFs with precise control over design and content. It is designed to be fast, memory-efficient, and easy to integrate into .NET applications without external dependencies.
Developers should use QuestPDF when building .NET applications that require dynamic PDF generation, such as reports, invoices, labels, or certificates, where performance and maintainability are key. It is ideal for scenarios needing pixel-perfect layouts, reusable components, and integration with data sources like databases or APIs, offering a more developer-friendly alternative to traditional PDF tools.
