What is it?

QuestPDF lets .NET developers define PDF layouts directly in C# using a fluent, component-based API. Pages, headers, footers, tables, rows, columns, images, SVG and rich text are all composed in code, so layouts can use normal language features such as loops, conditionals and reusable functions.

Because the document is built from code rather than rendered from HTML and CSS, layout results are intended to match what the code describes. The library also supports RTL text, font fallback, PDF/A and PDF/UA output, and ZUGFeRD/Factur-X e-invoicing. A separate operations API can merge, split, encrypt and attach files to existing PDFs.

It targets .NET 6+ and .NET Framework 4.6.2+, runs on Windows, Linux and macOS, and is distributed as a NuGet package. A companion app provides live preview and hot reload during development.
