Large PDF files can sometimes be cumbersome to handle, especially when sharing or uploading them. Splitting a large PDF file into multiple smaller PDFs reduces the file size, making it more manageable and quicker to open and process. In this article, we will demonstrate how to split PDF documents in Python using Spire.PDF for Python.

• Split a PDF File into Multiple Single-Page PDFs in Python
• Split a PDF File by Page Ranges in Python

Split a PDF File into Multiple Single-Page PDFs in Python

Spire.PDF for Python offers the PdfDocument.Split() method to divide a multi-page PDF document into multiple single-page PDF files. The following are the detailed steps.

• Create a PdfDocument object.
• Load a PDF document using PdfDocument.LoadFromFile() method.
• Split the document into multiple single-page PDFs using PdfDocument.Split() method.

from spire.pdf.common import *
from spire.pdf import *

# Create a PdfDocument object
doc = PdfDocument()
# Load a PDF file
doc.LoadFromFile("Sample.pdf")

# Split the PDF file into multiple single-page PDFs
doc.Split("Output/SplitDocument-{0}.pdf", 1)

# Close the PdfDocument object
doc.Close()

Split a PDF File by Page Ranges in Python

To split a PDF file into two or more PDF files by page ranges, you need to create two or more new PDF files, and then import the specific page or range of pages from the source PDF into the newly created PDF files. The following are the detailed steps.

• Create a PdfDocument object.
• Load a PDF document using PdfDocument.LoadFromFile() method.
• Create three PdfDocument objects.
• Import the first page from the source file into the first document using PdfDocument.InsertPage() method.
• Import pages 2-4 from the source file into the second document using PdfDocument.InsertPageRange() method.
• Import the remaining pages from the source file into the third document using PdfDocument.InsertPageRange() method.
• Save the three documents using PdfDocument.SaveToFile() method.

from spire.pdf.common import *
from spire.pdf import *

# Create a PdfDocument object
doc = PdfDocument()
# Load a PDF file
doc.LoadFromFile("Sample.pdf")

# Create three PdfDocument objects
newDoc_1 = PdfDocument()
newDoc_2 = PdfDocument()
newDoc_3 = PdfDocument()

# Insert the first page of the source file into the first document
newDoc_1.InsertPage(doc, 0)

# Insert pages 2-4 of the source file into the second document
newDoc_2.InsertPageRange(doc, 1, 3)

# Insert the rest pages of the source file into the third document
newDoc_3.InsertPageRange(doc, 4, doc.Pages.Count - 1)

# Save the three documents
newDoc_1.SaveToFile("Output1/Split-1.pdf")
newDoc_2.SaveToFile("Output1/Split-2.pdf")
newDoc_3.SaveToFile("Output1/Split-3.pdf")

# Close the PdfDocument objects
doc.Close()
newDoc_1.Close()
newDoc_2.Close()
newDoc_3.Close()
