Overview

Syncfusion Essential PDF is a .NET PDF library that allows you to split a PDF file into different sub-documents quickly and accurately. The split PDF functionality can be used in any .NET application, whether it is Windows Forms, WPF, ASP.NET (Web Forms, MVC, Core), or even UWP, Xamarin.Forms, Xamarin.Android, and Xamarin.iOS. It will help you split, combine, import, and append PDFs with just a few lines of code using C# or VB.NET.


Split PDFs

Developers can easily and accurately disassemble a multiple-page PDF document into two or more separate PDF files. It is also possible to generate files with a destination file name pattern. Besides this process, developers can also:

  • Import or delete certain pages from a PDF file.
  • Split PDF documents into multiple files.
  • Split PDF document into a separate PDF file.
  • Split a range of pages into a separate PDF document.
  • Split a PDF document based on the bookmarks.
  • Password-protect a split PDF file.
  • Find a specific text on a page and split it into a separate PDF document.
  • Split a PDF document into multiple files with a specific range of pages.

Split PDF document into multiple files code example

Easily split each page in a PDF document into individual PDF documents using a few lines of C# code as demonstrated in the following sample. Also explore our .NET PDF example that shows how to create and modify PDF files from C# with 5 lines of code on different platforms.

//Load an existing PDF document.
PdfLoadedDocument loadedDocument = new PdfLoadedDocument("Input.pdf");

//Set patterns.
const string destinationFilePattern = "Output" + "{0}.pdf";

//Split the pages into separate documents.
loadedDocument.Split(destinationFilePattern);

//Close the document.
loadedDocument.Close(true);
'Load an existing PDF document.
Dim loadedDocument As New PdfLoadedDocument("Input.pdf")

'Set patterns.
Const destinationFilePattern As String = "Output" + "{0}.pdf"

'Split the pages into separate documents.
loadedDocument.Split(destinationFilePattern)

'Close the document.
loadedDocument.Close(True)
