Organize your PDF Structure

Let's first take a look at some of the features IronPDF has to offer to help you take control of your PDF file's structure. Using these tools, you can easily manipulate the pages within your PDF document and control their positioning.

Manage your PDF Pages

Add new content to your PDF documents by adding new pages, deleting unnecessary pages from your files, and even copying specific pages to create duplicates. By manipulating the pages within your PDF, you can easily restructure the PDF to fit your needs.

Add Pages

Add a new page to your PDF in just a few lines of code. With IronPDF, adding new content to your PDF files is a breeze.

:path=/static-assets/pdf/content-code-examples/how-to/add-copy-delete-pages-pdf-add.cs
using IronPdf;

// Import cover page
PdfDocument coverPage = PdfDocument.FromFile("coverPage.pdf");

// Import content document
PdfDocument contentPage = PdfDocument.FromFile("contentPage.pdf");

// Merge the two documents
PdfDocument finalPdf = PdfDocument.Merge(coverPage, contentPage);

finalPdf.SaveAs("pdfWithCover.pdf");
Imports IronPdf

' Import cover page
Private coverPage As PdfDocument = PdfDocument.FromFile("coverPage.pdf")

' Import content document
Private contentPage As PdfDocument = PdfDocument.FromFile("contentPage.pdf")

' Merge the two documents
Private finalPdf As PdfDocument = PdfDocument.Merge(coverPage, contentPage)

finalPdf.SaveAs("pdfWithCover.pdf")
$vbLabelText   $csharpLabel

This method simplifies the process of adding new pages. To add a new page at a specific index within a multi-paged PDF document, you can easily achieve this using the InsertPdf method:

:path=/static-assets/pdf/content-code-examples/how-to/add-copy-delete-pages-pdf-insert.cs
using IronPdf;

// Import cover page
PdfDocument coverPage = PdfDocument.FromFile("coverPage.pdf");

// Import content document
PdfDocument contentPage = PdfDocument.FromFile("contentPage.pdf");

// Insert PDF
contentPage.InsertPdf(coverPage, 0);
Imports IronPdf

' Import cover page
Private coverPage As PdfDocument = PdfDocument.FromFile("coverPage.pdf")

' Import content document
Private contentPage As PdfDocument = PdfDocument.FromFile("contentPage.pdf")

' Insert PDF
contentPage.InsertPdf(coverPage, 0)
$vbLabelText   $csharpLabel

Copy Pages

By copying pages within your PDF document, you can easily maintain a consistent style and transfer information across multiple PDF files. IronPDF's CopyPage and CopyPages methods offer a simple way to duplicate specific pages in your PDFs with just a few lines of code.

:path=/static-assets/pdf/content-code-examples/how-to/add-copy-delete-pages-pdf-copy.cs
using IronPdf;
using System.Collections.Generic;

// Copy a single page into a new PDF object
PdfDocument myReport = PdfDocument.FromFile("report_final.pdf");
PdfDocument copyOfPageOne = myReport.CopyPage(0);

// Copy multiple pages into a new PDF object
PdfDocument copyOfFirstThreePages = myReport.CopyPages(new List<int> { 0, 1, 2 });
Imports IronPdf
Imports System.Collections.Generic

' Copy a single page into a new PDF object
Private myReport As PdfDocument = PdfDocument.FromFile("report_final.pdf")
Private copyOfPageOne As PdfDocument = myReport.CopyPage(0)

' Copy multiple pages into a new PDF object
Private copyOfFirstThreePages As PdfDocument = myReport.CopyPages(New List(Of Integer) From {0, 1, 2})
$vbLabelText   $csharpLabel

Delete Pages

To delete specific pages from your PDF, you can use the RemovePage and RemovePages methods, allowing you to programmatically remove unwanted pages from your documents.

:path=/static-assets/pdf/content-code-examples/how-to/add-copy-delete-pages-pdf-delete.cs
using IronPdf;
using System.Collections.Generic;

PdfDocument pdf = PdfDocument.FromFile("full_report.pdf");

// Remove a single page
pdf.RemovePage(0);

// Remove multiple pages
pdf.RemovePages(new List<int> { 2, 3 });
Imports IronPdf
Imports System.Collections.Generic

Private pdf As PdfDocument = PdfDocument.FromFile("full_report.pdf")

' Remove a single page
pdf.RemovePage(0)

' Remove multiple pages
pdf.RemovePages(New List(Of Integer) From {2, 3})

Merge or Split PDFs

Merge PDFs

Combine multiple PDF documents into a single, easy-to-share PDF using IronPDF's merge tool. This feature is particularly useful when you want to group similar documents for easier distribution, merge individual pages into a new PDF, or carry out various other PDF merging tasks. With IronPDF's merge tool, you can automate this process effortlessly by utilizing the Merge method.

:path=/static-assets/pdf/content-code-examples/how-to/merge-or-split-pdfs-merge.cs
using IronPdf;

// Two paged PDF
const string html_a =
    @"<p> [PDF_A] </p>
    <p> [PDF_A] 1st Page </p>
    <div style = 'page-break-after: always;' ></div>
    <p> [PDF_A] 2nd Page</p>";

// Two paged PDF
const string html_b =
    @"<p> [PDF_B] </p>
    <p> [PDF_B] 1st Page </p>
    <div style = 'page-break-after: always;' ></div>
    <p> [PDF_B] 2nd Page</p>";

var renderer = new ChromePdfRenderer();

var pdfdoc_a = renderer.RenderHtmlAsPdf(html_a);
var pdfdoc_b = renderer.RenderHtmlAsPdf(html_b);

// Four paged PDF
var merged = PdfDocument.Merge(pdfdoc_a, pdfdoc_b);
merged.SaveAs("Merged.pdf");
Imports IronPdf

' Two paged PDF
Private Const html_a As String = "<p> [PDF_A] </p>
    <p> [PDF_A] 1st Page </p>
    <div style = 'page-break-after: always;' ></div>
    <p> [PDF_A] 2nd Page</p>"

' Two paged PDF
Private Const html_b As String = "<p> [PDF_B] </p>
    <p> [PDF_B] 1st Page </p>
    <div style = 'page-break-after: always;' ></div>
    <p> [PDF_B] 2nd Page</p>"

Private renderer = New ChromePdfRenderer()

Private pdfdoc_a = renderer.RenderHtmlAsPdf(html_a)
Private pdfdoc_b = renderer.RenderHtmlAsPdf(html_b)

' Four paged PDF
Private merged = PdfDocument.Merge(pdfdoc_a, pdfdoc_b)
merged.SaveAs("Merged.pdf")
$vbLabelText   $csharpLabel

Split PDFs

Just as you might want to merge multiple PDFs into one singular, easy-to-share PDF document, there might also be times when you want to split a multipage PDF file into separate documents.

:path=/static-assets/pdf/content-code-examples/how-to/merge-or-split-pdfs-split.cs
using IronPdf;

// We will use the 4-page PDF from the Merge example above:
var pdf = PdfDocument.FromFile("Merged.pdf");

// Takes only the first page into a new PDF
var page1doc = pdf.CopyPage(0);
page1doc.SaveAs("Page1Only.pdf");

// Take the pages 2 & 3 (Note: index starts at 0)
var page23doc = pdf.CopyPages(1, 2);
page23doc.SaveAs("Pages2to3.pdf");
Imports IronPdf

' We will use the 4-page PDF from the Merge example above:
Private pdf = PdfDocument.FromFile("Merged.pdf")

' Takes only the first page into a new PDF
Private page1doc = pdf.CopyPage(0)
page1doc.SaveAs("Page1Only.pdf")

' Take the pages 2 & 3 (Note: index starts at 0)
Dim page23doc = pdf.CopyPages(1, 2)
page23doc.SaveAs("Pages2to3.pdf")
$vbLabelText   $csharpLabel

Split Multipage PDF

To split multipage PDFs, we will follow a similar approach to splitting single-page PDFs. In this case, we will use a for loop to accomplish the task.

:path=/static-assets/pdf/content-code-examples/how-to/split-multipage-pdf-split-pdf.cs
using IronPdf;

PdfDocument pdf = PdfDocument.FromFile("multiPage.pdf");

for (int idx = 0; idx < pdf.PageCount; idx++)
{
    // Create new document for each page
    PdfDocument outputDocument = pdf.CopyPage(idx);

    string fileName = @$"multiPage - Page {idx + 1}_tempfile.pdf";

    // Export to new file
    outputDocument.SaveAs(fileName);
}
Imports IronPdf

Private pdf As PdfDocument = PdfDocument.FromFile("multiPage.pdf")

For idx As Integer = 0 To pdf.PageCount - 1
	' Create new document for each page
	Dim outputDocument As PdfDocument = pdf.CopyPage(idx)

	Dim fileName As String = $"multiPage - Page {idx + 1}_tempfile.pdf"

	' Export to new file
	outputDocument.SaveAs(fileName)
Next idx

using IronPdf;

// Create a new PDF or edit an existing document.
PdfDocument pdf = PdfDocument.FromFile("existing.pdf");

// Add a bookmark
pdf.Bookmarks.AddBookMarkAtEnd("NameOfBookmark", 0);

// Add a sub-bookmark
pdf.Bookmarks.AddBookMarkAtEnd("NameOfSubBookmark", 1);

pdf.SaveAs("singleLayerBookmarks.pdf");
Imports IronPdf
