# 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")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.
Split PDF Output
Implementing Security Features
Securing your PDF documents becomes a top priority when dealing with sensitive or confidential information.

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

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")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

# 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
License.LicenseKey = "Your-License-Key"
# Enable logging for debugging purposes

# 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)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

# 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"
