Adding pages to a PDF involves the insertion of new content, like text, images, or existing PDF pages, into the document. Copying pages in a PDF means duplicating one or more pages within the same document or from one PDF file to another. Deleting pages from a PDF involves the removal of unwanted pages from the document.

Add Pages to a PDF

Adding a page to a PDF can be done in one line of code. In this example, a PDF of a report is generated and a cover page will be added to the start of it. To combine both PDFs, the Merge method is used. Let's take these two PDF documents for our example: download coverPage.pdf and download contentPage.pdf.

: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

When we run the code above, we get a single PDF file as output, which has the cover page at the front:

We can also add a page at any index of the PDF using the InsertPdf method. In this example, I achieve the above effect by inserting 'coverPage.pdf' at the beginning of 'contentPage.pdf'.

: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 from a PDF

To copy pages from a PDF, simply call either the CopyPage or CopyPages methods. These are used to copy single and multiple pages, respectively. The methods return the PdfDocument object containing the specified pages.

: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 in a PDF

To delete pages from a PDF, you can call either the RemovePage or RemovePages methods. These are used to delete single and multiple pages, respectively.

: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})
$vbLabelText   $csharpLabel
