Splitting a multi-page PDF document into separate PDFs, each containing one page, can be done with just a couple of lines of code. See our example to implement it in your project.

With IronPDF, it is very easy to split a single PDF document into multiple documents, each containing only one page.

Split a Multipage PDF

Now that you have IronPDF, you can take a multipage document and split it into single-page document files. The idea of splitting a multipage PDF involves copying a single or multiple pages using the CopyPage or CopyPages method.

: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

Looking at the code above, you can see that it uses a for loop to iterate through the current PDF document's pages, then uses the CopyPage method to copy each page into a new PdfDocument object. Finally, each page is exported as a new document named sequentially.
