This article explains how to merge PDF using Python. It contains a step-by-step process, an introduction to classes and methods required to write the application, and finally to merge PDF files Python code is shared. You will also learn different options to customize the concatenation process using different methods and properties.

Steps to Combine PDF using Python

1. Configure the IDE to use Aspose.PDF for Python via .NET
2. Instantiate a PdfFileEditor object to combine multiple PDF files
3. Create an array of strings having the path and name of all the PDF files to be merged
4. Call the PdfFileEditor.concatenate method in the PdfFileEditor object to combine all the PDF files and save them on the disk

These steps briefly define the process to merge PDF using Python. In this process facades.PdfFileEditor class is used that contains methods to combine multiple PDF files. It requires an array of strings containing the full paths to the PDF files that are to be merged and then concatenate method is used to generate the output PDF files having all the PDF files in it.

Code to Merge PDF Files using Python

The aforementioned code demonstrates Python code to merge PDF files. The aspose.pdf.facades.PdfFileEditor class is used for combining the PDF files using the concatenate() method that requires the list of PDF file names to be merged and the name of the output resultant PDF file name. It is not necessary to save the output to a disk as you can save the output PDF file to a HttpResponse and set the flag to close the stream after the operation, and also use other overloaded methods of concatenate() to combine PDF files in different ways.

This article has taught us how using Python merge PDF files with the help of a few API calls. If you want to learn the process to create a PDF from scratch, refer to the article on how to create PDF in Python.
