4. Split PDF Document Using IronPDF for Python

In this article, we will delve into the world of splitting PDFs using IronPDF for Python, exploring its features, functionalities, and demonstrating how it simplifies the often-complex task of extracting and managing PDF content, all while enhancing your Python-powered document processing endeavors.

In the code snippet below, we will see how you can easily split a PDF with just a few lines of code.

from ironpdf import *
html = """<p> Hello Iron </p>
          <p> This is the 1st Page </p>
          <div style='page-break-after: always;'></div>
          <p> This is the 2nd Page</p>
          <div style='page-break-after: always;'></div>
          <p> This is the 3rd Page</p>"""
renderer = ChromePdfRenderer()
pdf = renderer.RenderHtmlAsPdf(html)

# Take the first page
page1doc = pdf.CopyPage(0)
page1doc.SaveAs("Split1.pdf")

# Take pages 2 & 3
page23doc = pdf.CopyPages(1, 2)
page23doc.SaveAs("Split2.pdf")

from ironpdf import *
html = """<p> Hello Iron </p>
          <p> This is the 1st Page </p>
          <div style='page-break-after: always;'></div>
          <p> This is the 2nd Page</p>
          <div style='page-break-after: always;'></div>
          <p> This is the 3rd Page</p>"""
renderer = ChromePdfRenderer()
pdf = renderer.RenderHtmlAsPdf(html)

# Take the first page
page1doc = pdf.CopyPage(0)
page1doc.SaveAs("Split1.pdf")

# Take pages 2 & 3
page23doc = pdf.CopyPages(1, 2)
page23doc.SaveAs("Split2.pdf")

This Python script leverages IronPDF to split an HTML document into separate PDF files. It starts by defining an HTML content string containing multiple paragraphs, with page breaks indicated by the <div style='page-break-after: always;'></div> element. Next, it utilizes IronPDF's ChromePdfRenderer to render the HTML as a new PDF file.

Then, it copies the first page based on the page index (starting from 0) of the original file into a separate document named "Split1.pdf" using the function pdf.CopyPage(0). Finally, it creates another PDF containing the second and third PDF pages based on the number of pages using the function pdf.CopyPages(1, 2) and saves it as a new file named "Split2.pdf". This code showcases how IronPDF facilitates the extraction and splitting of PDF content into several PDF files, making it a valuable tool for PDF document manipulation in Python applications.

4.1. Output PDF Files

You can also split existing PDFs into several pages in a new PDF document format. To split an existing PDF into multiple PDF files, follow the code example below:

from ironpdf import *

pdf = PdfDocument("document.pdf")
page1doc = pdf.CopyPage(0, 1)
page1doc.SaveAs("Split1.pdf")
page23doc = pdf.CopyPages(2, 3)
page23doc.SaveAs("Split2.pdf")

from ironpdf import *

pdf = PdfDocument("document.pdf")
page1doc = pdf.CopyPage(0, 1)
page1doc.SaveAs("Split1.pdf")
page23doc = pdf.CopyPages(2, 3)
page23doc.SaveAs("Split2.pdf")

The above code opens an existing PDF using the PdfDocument method by providing the original file name and splits it into two separate PDF files.
