Modifying PDF file using Python Last Updated : 18 May, 2022 Comments Improve Suggest changes Like Article Like Report The following article depicts how a PDF can be modified using python's pylovepdf module. The Portable Document Format(PDF) is a file format developed by Adobe in 1993 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. pylovepdf module can be downloaded using pip command: pip install pylovepdf The iLovePDF API i.e 'pylovepdf' module is organized around REST. Their API are predictable, resource-oriented URLs, and uses HTTP response codes to indicate API errors. They use built-in HTTP features, like HTTP authentication and HTTP verbs, which are understood by off-the-shelf HTTP clients. They support cross-origin resource sharing, allowing you to interact securely with their API from a client-side web application. With this API we can compress the PDF files, also can add watermark, convert them to images and even split them and vice -versa and lots of other stuff. In order to do so first we need a public-key to use this module, for that login on to https://developer.ilovepdf.com/ and after login the public key will be visible in the 'My Projects' section. Below is the screenshot of the public key Now since we have our public key, we can use this API for modifying any PDF file using the steps given below: 1. Creating a ILovePdf object using the public key2. Uploading the PDF file3. Processing the PDF file4. Downloading the PDF file Implementation of this module is depicted properly using examples. Click here for the PDF used in the examples provided in this article: Example 1: Compressing the PDF file Python3 # importing the ilovepdf api from pylovepdf.ilovepdf import ILovePdf # public key public_key = 'paste_your_public_key_here' # creating a ILovePdf object ilovepdf = ILovePdf(public_key, verify_ssl=True) # assigning a new compress task task = ilovepdf.new_task('compress') # adding the pdf file to the task task.add_file('my_pdf.pdf') # setting the output folder directory # if no folder exist it will create one task.set_output_folder('output_folder') # execute the task task.execute() # download the task task.download() # delete the task task.delete_current_task() Before processing: Output : After Processing: Example 2: Splitting the PDF Python # public key from pylovepdf.ilovepdf import ILovePdf public_key = 'paste your code here' # importing the ilovepdf api # creating a ILovePdf object ilovepdf = ILovePdf(public_key, verify_ssl=True) # assigning a new split task task = ilovepdf.new_task('split') # adding the pdf file to the task task.add_file('my_pdf.pdf') # setting the output folder directory # if no folder exist it will create one task.set_output_folder('output_folder') # execute the task task.execute() # download the task task.download() # delete the task task.delete_current_task() Output : After processing: zip Comment More infoAdvertise with us Next Article Modifying PDF file using Python R rakshitarora Follow Improve Article Tags : Technical Scripter Python Technical Scripter 2020 python-utility Practice Tags : python Similar Reads Setting file offsets in Python Prerequisite: seek(), tell() Python makes it extremely easy to create/edit text files with a minimal amount of code required.
