Logger.LoggingMode = Logger.LoggingModes.All

# Load existing PDF documents
pdfOne = PdfDocument("Report First.pdf")
pdfTwo = PdfDocument("Report Second.pdf")
# Merge the PDFs into a single document
merged = PdfDocument.Merge(pdfOne, pdfTwo)
# Save the merged PDF
merged.SaveAs("Merged.pdf")
from ironpdf import PdfDocument, License, Logger

# Set the IronPDF license key
License.LicenseKey = "Your-License-Key"
# Enable logging for debugging purposes
Logger.EnableDebugging = True
Logger.LogFilePath = "Custom.log"
Logger.LoggingMode = Logger.LoggingModes.All

# Load existing PDF documents
pdfOne = PdfDocument("Report First.pdf")

Splitting a Single PDF

Conversely, IronPDF also excels at dividing an existing PDF file into multiple new files. This function is handy when you need to extract specific sections from a substantial PDF document or when dividing a document into smaller, more manageable parts.

from ironpdf import PdfDocument, License, Logger

# Set the IronPDF license key
License.LicenseKey = "Your-License-Key"
# Enable logging for debugging purposes
Logger.EnableDebugging = True
Logger.LogFilePath = "Custom.log"
Logger.LoggingMode = Logger.LoggingModes.All

# Load the PDF document
pdf = PdfDocument("Report.pdf")
# Extract the first page
page1doc = pdf.CopyPage(0)
# Save the extracted page as a new PDF
page1doc.SaveAs("Split1.pdf")
from ironpdf import PdfDocument, License, Logger

# Set the IronPDF license key
License.LicenseKey = "Your-License-Key"
# Enable logging for debugging purposes
Logger.EnableDebugging = True
Logger.LogFilePath = "Custom.log"
Logger.LoggingMode = Logger.LoggingModes.All

# Load the PDF document
pdf = PdfDocument("Report.pdf")
# Extract the first page
page1doc = pdf.CopyPage(0)
# Save the extracted page as a new PDF
page1doc.SaveAs("Split1.pdf")
PYTHON

For example, you might want to isolate certain PDF pages from a large report or create individual documents from different chapters of a book. IronPDF lets you select the desired multiple pages to convert into a new PDF file, ensuring you can manipulate and manage your PDF content as needed.

Implementing Security Features

Securing your PDF documents becomes a top priority when dealing with sensitive or confidential information. IronPDF addresses this need by offering robust security features, including user password protection and encryption. This ensures that your PDF files remain secure and accessible only to authorized users.

from ironpdf import PdfDocument, License, Logger

# Set the IronPDF license key
License.LicenseKey = "Your-License-Key"
# Enable logging for debugging purposes
Logger.EnableDebugging = True
Logger.LogFilePath = "Custom.log"
Logger.LoggingMode = Logger.LoggingModes.All

# Load the PDF document
pdf = PdfDocument("Report.pdf")
# Adjust security settings to make the PDF read-only and set permissions
pdf.SecuritySettings.RemovePasswordsAndEncryption()
pdf.SecuritySettings.MakePdfDocumentReadOnly("secret-key")
pdf.SecuritySettings.AllowUserAnnotations = False
pdf.SecuritySettings.AllowUserCopyPasteContent = False
pdf.SecuritySettings.AllowUserFormData = False
pdf.SecuritySettings.AllowUserPrinting = PdfPrintSecurity.FullPrintRights
# Set the document encryption passwords
pdf.SecuritySettings.OwnerPassword = "top-secret"  # password to edit the PDF
pdf.SecuritySettings.UserPassword = "sharable"  # password to open the PDF
# Save the secured PDF
pdf.SaveAs("secured.pdf")
from ironpdf import PdfDocument, License, Logger

# Set the IronPDF license key
License.LicenseKey = "Your-License-Key"
# Enable logging for debugging purposes
Logger.EnableDebugging = True
Logger.LogFilePath = "Custom.log"
Logger.LoggingMode = Logger.LoggingModes.All

# Load the PDF document
pdf = PdfDocument("Report.pdf")
# Adjust security settings to make the PDF read-only and set permissions
pdf.SecuritySettings.RemovePasswordsAndEncryption()
pdf.SecuritySettings.MakePdfDocumentReadOnly("secret-key")
pdf.SecuritySettings.AllowUserAnnotations = False
pdf.SecuritySettings.AllowUserCopyPasteContent = False
pdf.SecuritySettings.AllowUserFormData = False
pdf.SecuritySettings.AllowUserPrinting = PdfPrintSecurity.FullPrintRights
# Set the document encryption passwords
pdf.SecuritySettings.OwnerPassword = "top-secret"  # password to edit the PDF
pdf.SecuritySettings.UserPassword = "sharable"  # password to open the PDF
# Save the secured PDF
pdf.SaveAs("secured.pdf")
PYTHON

By implementing user passwords, you can control who can view or edit your PDF documents. Encryption options add an extra layer of security, safeguarding your data against unauthorized access and making IronPDF a reliable choice for managing sensitive information in PDF format.

Extracting Text from PDFs

Another critical feature of IronPDF is its ability to extract text from PDF documents. This functionality is particularly useful for data retrieval, content analysis, or even for repurposing text content from existing PDFs into new documents.

from ironpdf import PdfDocument, License, Logger

# Set the IronPDF license key
License.LicenseKey = "Your-License-Key"
# Enable logging for debugging purposes
Logger.EnableDebugging = True
Logger.LogFilePath = "Custom.log"
Logger.LoggingMode = Logger.LoggingModes.All

# Load the PDF document
pdf = PdfDocument("Report.pdf")
# Extract all text from the PDF document
allText = pdf.ExtractAllText()
# Extract text from a specific page in the document
specificPage = pdf.ExtractTextFromPage(3)
from ironpdf import PdfDocument, License, Logger

# Set the IronPDF license key

Whether you're extracting data for analysis, searching for specific information within a large document, or transitioning content from PDF to text files for further processing, IronPDF makes it straightforward and efficient. The library ensures that the extracted text maintains its original formatting and structure, making it immediately usable for your specific needs.

Managing Document Information

Efficient management of PDFs extends beyond their content. IronPDF allows for effectively managing document metadata and properties such as the author's name, document title, creation date, and more. This capability is vital for organizing and cataloging your PDF documents, particularly in environments where document provenance and metadata are important.

from ironpdf import PdfDocument, License, Logger
from datetime import datetime

# Set the IronPDF license key
License.LicenseKey = "Your-License-Key"
# Enable logging for debugging purposes
Logger.EnableDebugging = True
Logger.LogFilePath = "Custom.log"
Logger.LoggingMode = Logger.LoggingModes.All

# Load an existing PDF or create a new one
pdf = PdfDocument("Report.pdf")
# Edit file metadata
pdf.MetaData.Author = "Satoshi Nakamoto"
pdf.MetaData.Keywords = "SEO, Friendly"
pdf.MetaData.ModifiedDate = datetime.now()
# Save the PDF with updated metadata
pdf.SaveAs("MetaData Updated.pdf")
from ironpdf import PdfDocument, License, Logger
from datetime import datetime

# Set the IronPDF license key
License.LicenseKey = "Your-License-Key"
# Enable logging for debugging purposes
Logger.EnableDebugging = True
Logger.LogFilePath = "Custom.log"
Logger.LoggingMode = Logger.LoggingModes.All

# Load an existing PDF or create a new one
pdf = PdfDocument("Report.pdf")
# Edit file metadata
pdf.MetaData.Author = "Satoshi Nakamoto"
pdf.MetaData.Keywords = "SEO, Friendly"
pdf.MetaData.ModifiedDate = datetime.now()
# Save the PDF with updated metadata
pdf.SaveAs("MetaData Updated.pdf")
PYTHON

For instance, in an academic or corporate setting, being able to track the creation date and authorship of documents can be essential for record-keeping and document retrieval purposes. IronPDF makes managing this information easy, providing a streamlined way to handle and update document information within your Python applications.
