// QuestPDF.Settings.License = LicenseType.Community;

Document.Create(container =>
{
 container.Page(page =>
 {
 page.Size(PageSizes.A4);
 page.Margin(2, Unit.Centimetre);
 page.PageColor(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");

Familiar Programming Patterns

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.

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));
});

Review document changes like any other code. Get clean diffs, PR approvals, and traceable history.

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");
 });
}
