QuestPDF Report Generation

Overview

QuestPDF is a modern C# library for PDF document generation with a dedicated layout engine optimized for PDF creation. It uses a component-based, fluent API architecture where simple elements are composed into sophisticated documents.

Key Benefits

Feature	Description
Native C# API	No HTML-to-PDF conversion - direct PDF generation
Component-Based	Reusable IComponent pattern for modular documents
Automatic Pagination	Content flows naturally across pages
Type-Safe	Compile-time checked document structure
Fluent API	Intuitive chaining syntax for layout definition

Installation

dotnet add package QuestPDF

License: Free for individuals, non-profits, and businesses < $1M annual revenue.

Quick Start

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

Document.Create(container =>
{
    container.Page(page =>
    {
        page.Size(PageSizes.A4);
        page.Margin(50);

        page.Header().Text("My Report").FontSize(24).Bold();

        page.Content().Column(column =>
        {
            column.Spacing(10);
            column.Item().Text("Hello, QuestPDF!");
            column.Item().Text($"Generated: {DateTime.Now:g}");
        });

        page.Footer().AlignCenter().Text(text =>
        {
            text.Span("Page ");
            text.CurrentPageNumber();
            text.Span(" of ");
            text.TotalPages();
        });
    });
}).GeneratePdf("report.pdf");

Common Pitfalls

Pitfall	Solution
Constraint conflicts	Ensure parent containers provide sufficient space for width/height constraints
Header/Footer height	Combined header + footer must leave space for content
Image loading	Load images once and reuse for performance
Text overflow	Use `.ClampLines()` or ensure adequate width
DateTime metadata	Use `DateTimeOffset.Now` instead of `DateTime.Now`
