Generate and manipulate PDF documents in your .NET applications using the open-source QuestPDF library and its C# Fluent API.

Quick Start

Learn how easy it is to design, implement and generate PDF documents using QuestPDF. Effortlessly create documents of all types such as invoices and reports.

using QuestPDF.Fluent;
using QuestPDF.Helpers;
using QuestPDF.Infrastructure;

// code in your main method
Document.Create(container =>
{
    container.Page(page =>
    {
        page.Size(PageSizes.A4);
        page.Margin(2, Unit.Centimetre);
        page.Background(Colors.White);
        page.DefaultTextStyle(x => x.FontSize(20));
        
        page.Header()
            .Text("Hello PDF!")
            .SemiBold().FontSize(36).FontColor(Colors.Blue.Medium);
        
        page.Content()
            .PaddingVertical(1, Unit.Centimetre)
            .Column(x =>
            {
                x.Spacing(20);
                
                x.Item().Text(Placeholders.LoremIpsum());
                x.Item().Image(Placeholders.Image(200, 100));
            });
        
        page.Footer()
            .AlignCenter()
            .Text(x =>
            {
                x.Span("Page ");
                x.CurrentPageNumber();
            });
    });
})
.GeneratePdf("hello.pdf");

Code-Focused Paradigm

Modular and Maintainable C# Code

Implement modular PDF layouts with reusable well-organized classes and methods. Refactor safely with IntelliSense - your logic stays seamlessly integrated with your domain code.

Familiar Programming Concepts

Use conditions, loops, LINQ, and extension methods to effortlessly generate dynamic, data-driven PDF documents tailored to your unique business needs.

Git-Friendly Workflow

Enjoy straightforward C# code reviews, meaningful pull-request diffs, and cleaner version control histories.

.Column(column =>
{
    if (Model.Comments != null)
        column.Item().Text(Model.Comments);

    foreach(var item in Model.Items)
       column.Item().Element(c => CreateItem(c, item);
});

void CreateItem(IContainer container, Item item)
{
    container
-       .Background(Colors.Grey.Lighten2)
+       .Background(item.Color)
        .Padding(10)
        .Text(item.Text);
}

Companion App

Accelerate your development with live document preview powered by the hot-reload capability, eliminating the need for C# code recompilation.

• Explore PDF document structure and hierarchy
• Quickly magnify and measure content
