How to Edit PDF Using Python? (Step by Step)

Python is the most advanced programming language that allows you to automate various tasks. For those who use Python frequently, you may want to know how to edit PDF using Python. Whether you need to update text or extract content from PDF, Python is the best tool.

And, in this guide, we will also introduce you to the best alternative available, UPDF PDF editor in case you do not want to use Python. Let's explore the detailed steps regarding using both tools for smoother work.

Part 1. How to Edit PDF with Python?

Have you ever heard that Python can be really helpful when it comes to editing PDF files? Well, using Python, developers can easily modify PDFs using a modern and easy-to-use library. This means you can add, change, or remove elements in your PDFs directly from your code. So, this removes the need to edit PDFs anymore manually. Python's library supports various document formats, making it even more powerful.

However, the task of editing PDF with Python programmatically might sound complex, but following the instructions given below can help you greatly. You must use the PyPi repository to install "Aspose.Words" for Python via .NET" in your developer environment. Also, ensure you have Python version 3.5 or later but not version 3.12.

Moreover, if you are using Linux, there are some extra things called gcc and libpython that you should start using this repository. Using pip is the simplest and easiest way to get Aspose.Words for Python with .NET. Run the provided command to download and install the package:

pip install aspose-words

As far as editing is concerned, run the following commands as per your requirements:

1. For Text Editing

import aspose.words as aw

doc = aw.Document("Input.pdf")

builder = aw.DocumentBuilder(doc)

# Insert text at the beginning of the document.


builder.writeln("Morbi enim nunc faucibus a.")


2. For Editing a Table

import aspose.words as aw

doc = aw.Document("Input.pdf")

builder = aw.DocumentBuilder(doc)

# Insert table at the beginning of the document.




builder.write("Row 1, cell 1.")


builder.write("Row 1, cell 2.")



3. For Editing an Image

import aspose.words as aw

doc = aw.Document("Input.pdf")

builder = aw.DocumentBuilder(doc)

# Insert image at the beginning of the document.




4. Cons of Using Python

  • Unable to edit the PDF changes in real time.
  • Formatting can be a big issue; you should run the whole process again.
  • Even minor edits require a dedicated code.
  • Not easily accessible to everyone.
  • You must have the basic programming knowledge to run codes.
  • Consumes a lot of memory and can be slow at times

Part 3. FAQS About Modifying PDF with Python

1. How do I add text to an existing PDF in Python?

To add a text string in a PDF document using Aspose.PDF Java for Python, you just need to use the “AddText” module simply. Run the given command to add any additional text to PDF:


doc=self.dataDir + 'input1.pdf'



text_fragment=self.TextFragment("main text")









# Save PDF file + "Text_Added.pdf")

print "Text added successfully"

2. What is the Python library for editing PDF files?

Besides Aspose.Words, the Python library you can use to edit PDF files, is called PyPDF2. It's a fantastic library that allows you to customize many things with PDF files. You can use it to extract specific information from a document, merge multiple PDF files into one, split pages, add watermarks, and even encrypt or decrypt PDF files.

3. How do I get the contents of a PDF in Python?

To easily extract text from a PDF in Python, you can use the PyPDF package. This package offers more functionality than we require for text extraction. To install the package, simply enter the following command in your terminal:

pip install PyPDF2

Now, after the package is installed, run the below-provided command for the required text extraction:

# importing required modules

from PyPDF2 import PdfReader

# creating a pdf reader object

reader = PdfReader('example.pdf')

# printing number of pages in pdf file


# getting a specific page from the pdf file

page = reader.pages[0]

# extracting text from page

text = page.extract_text()


Final Thoughts

In the end, it is now very clear that editing PDFs using Python is a complicated method to use. Moreover, it is time-consuming and complex for those without programming knowledge. Most of the time, even a single error in the above-given codes can mess up the whole editing process.
