QuestPDF is a PDF generation library for C# that lets you design documents using a fluent, component-based API with clean, strongly-typed code.
The library addresses the friction of HTML-to-PDF conversion by providing a native C# approach to document design. Instead of wrestling with HTML templates or external tools, developers write PDF layouts directly in C# using a declarative, composable API. The tool handles complex layouts through features including tables, multi-column flow, headers, footers, watermarks, rich text formatting, images, SVG support, and dynamic content rendering with loops and conditions. Layout control spans alignment, padding, rotation, scaling, and page break management, allowing pixel-perfect document generation.
QuestPDF suits teams already working in C# who need to generate invoices, reports, and data-driven exports as part of their applications. It works well for projects where document design benefits from being version-controlled alongside application code and where strong typing reduces errors. The library is free for individuals, non-profits, open-source projects, and organizations under a revenue threshold, with commercial licensing available for larger enterprises. Developers should evaluate whether the C#-native approach aligns with their workflow compared to HTML-based alternatives.
The project maintains active development with regular feature additions and refinements to its layout engine and visual capabilities. The maintainers engage directly with users through documentation and examples, including detailed tutorials for common use cases like invoice generation. The tool has reached production maturity with a stable API surface and comprehensive feature coverage across layout, styling, positioning, and content flow concerns.
