# 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.

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"

# 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")
