Code-first PDF generation for C#
QuestPDF is a production-ready library that lets you design documents the way you design software with clean, maintainable C# code.
HelloWorld.cs
Document
.Create(document =>
{
document.Page(page =>
{
page.Size(PageSizes.A4);
page.Margin(32);
page.Content()
.Text("Hello PDF!")
.FontSize(24);
});
})
.GeneratePdfAndShow();Experience the Simplicity
See how QuestPDF's Fluent API lets you build professional documents with just a few lines of readable, intuitive C# code.
Everything you need to generate PDFs
From layout and styling to production features, QuestPDF gives you the flexibility to create documents of any complexity.
Explore all features
Familiar Programming Patterns
Treat documents as application code: strongly-typed models, reusable components, and IDE-assisted refactoring. Catch issues early with compile-time feedback.
Dynamic Content Is Just Code
Use your existing programming language and patterns to ship faster with less training. Loops, conditionals, functions are natively supported. Leverage IntelliSense, inspections, navigation, and safe refactoring.
Version Control Friendly
Review document changes like any other code. Get clean diffs, PR approvals, and traceable history.
Ready for AI
A semantic Fluent API helps AI assistants generate layouts, refactor components, and troubleshoot issues effectively.
InvoiceDocument.cs
container.Column(column =>
{
column.Item().Text("Order Items").Bold();
if (Model.ShowSummary)
column.Item().Element(ComposeOrderSummary);
foreach (var item in Model.Items)
column.Item().Element(c => ComposeItem(c, item));
});
void ComposeItem(IContainer container, OrderItem item)
{
container
.Border(1, Colors.Grey.Darken2)
.Background(item.HighlightColor)
- .Padding(12)
+ .Padding(16)
.Row(row =>
{
row.RelativeItem().Text(item.Name);
row.AutoItem().Text($"{item.Price:F2} USD");
});
