from PyPDF2 import PdfMerger
# Create an object for merging
merger = PdfMerger()
# List of files to merge
pdf_files = ["file1.pdf", "file2.pdf", "file3.pdf"]
# Add files to the object
for file in pdf_files:
merger.append(file)
# Save the merged file
merger.write("merged.pdf")
merger.close()3. Run the script:
The result will be a new file merged.pdf containing all specified documents.
Using the Command Line (Ghostscript)
Ghostscript is a powerful tool for working with PDF files via the command line.
