Remove Specific PDF Pages

VB C#

using IronPdf;

// 4-Paged HTML Document example:
const string html =
    @"<p> Hello Iron</p>
    <p> This is 1st Page </p>
    <div style = 'page-break-after: always;' ></div>
    <p> This is 2nd Page</p>
    <div style = 'page-break-after: always;' ></div>
    <p> This is 3rd Page</p>
    <div style = 'page-break-after: always;' ></div>
    <p> This is 4th Page</p>";


var renderer = new ChromePdfRenderer();
var pdf = renderer.RenderHtmlAsPdf(html);

// Remove 2 & 3 pages. Similar syntax to to Substring
pdf.RemovePages(1, 2);

pdf.SaveAs("Page1And4.pdf");

Remove Specific PDF Pages

Removing Specific PDF Pages in C#

One method of altering your PDF document's structure is by removing specific pages from within the PDF. This can be used to remove unwanted or unnecessary pages from your PDFs, or to tidy up a PDF by removing blank pages. In IronPDF, this can be done in one simple line of code thanks to the RemovePages method.

Steps for Removing Specific PDF Pages in C#

Before we begin removing pages from our PDF, we must first create the example PDF for this code example. To do this, we have first created an HTML string with page breaks, which defines the content for a 4-page document. Then, we have created a new ChromePdfRenderer instance, which gives us access to IronPDF's powerful rendering engine. Finally, using RenderHtmlAsPdf, we convert the multi-paged HTML into a PDF document, ready to be manipulated and split.

Here is how you can remove specific pages using IronPDF in C#:

// Create an instance of the ChromePdfRenderer
var renderer = new ChromePdfRenderer();

// Define HTML content with page breaks to create a multi-page PDF
string html = "<div style='page-break-before:always;'>Page 1</div>" +
              "<div style='page-break-before:always;'>Page 2</div>" +
              "<div style='page-break-before:always;'>Page 3</div>" +
              "<div style='page-break-before:always;'>Page 4</div>";

// Render the HTML content as a PDF document
var pdf = renderer.RenderHtmlAsPdf(html);

// Remove pages 2 and 3 (note: page indexing is zero-based)
pdf.RemovePages(1, 2);

// Save the altered PDF document, which now contains only pages 1 and 4
pdf.SaveAs("Page1And4.pdf");

// Create an instance of the ChromePdfRenderer
var renderer = new ChromePdfRenderer();

// Define HTML content with page breaks to create a multi-page PDF
string html = "<div style='page-break-before:always;'>Page 1</div>" +
              "<div style='page-break-before:always;'>Page 2</div>" +
              "<div style='page-break-before:always;'>Page 3</div>" +
              "<div style='page-break-before:always;'>Page 4</div>";

// Render the HTML content as a PDF document
var pdf = renderer.RenderHtmlAsPdf(html);

// Remove pages 2 and 3 (note: page indexing is zero-based)
pdf.RemovePages(1, 2);

// Save the altered PDF document, which now contains only pages 1 and 4
pdf.SaveAs("Page1And4.pdf");

' Create an instance of the ChromePdfRenderer
Dim renderer = New ChromePdfRenderer()

' Define HTML content with page breaks to create a multi-page PDF
Dim html As String = "<div style='page-break-before:always;'>Page 1</div>" & "<div style='page-break-before:always;'>Page 2</div>" & "<div style='page-break-before:always;'>Page 3</div>" & "<div style='page-break-before:always;'>Page 4</div>"

' Render the HTML content as a PDF document
Dim pdf = renderer.RenderHtmlAsPdf(html)

' Remove pages 2 and 3 (note: page indexing is zero-based)
pdf.RemovePages(1, 2)

' Save the altered PDF document, which now contains only pages 1 and 4
pdf.SaveAs("Page1And4.pdf")

Explanation:

Creating the Renderer: We create an instance of ChromePdfRenderer to access IronPDF's PDF rendering capabilities.
Defining Document Content: HTML content with page breaks is defined to simulate a four-page document.
Rendering PDF: The HTML is converted into a PDF using the RenderHtmlAsPdf method.
Removing Pages: Using RemovePages, we remove pages at index 1 and 2, which correspond to the second and third pages in the PDF (remember, indexing starts at 0).
Saving the PDF: The edited PDF, now containing only the first and last pages, is saved to disk.

For situations where you only need to remove a single page, you would use the RemovePage() method, which removes the page at the specified zero-based index.

The new PDF will exclusively contain pages 1 and 4, demonstrating how straightforward it is to change your PDF's structure with IronPDF. From here, you can go on to further manipulate the PDF using IronPDF's variety of editing tools.
