How to Easily Add Links Between PDFs Using Python

Are you trying to insert hyperlinks into a PDF file that direct users to another PDF? If so, you're in the right place! Adding such links can greatly enhance the connectivity and navigability of your documents. In this guide, we'll explore how to use Python, specifically the PyMuPDF library, to accomplish this task effectively. Let’s dive in!

The Challenge: Adding Links Between PDFs

While working with PDF files, you might find the need to connect different documents or pages within a single document through hyperlinks. Let's say you want to link a page in Document A to another page in Document B. The common libraries like PyPDF2 can add internal links but are limited to linking within the same PDF, leaving you searching for alternatives for external links.

The Solution: Utilizing PyMuPDF

PyMuPDF offers a straightforward and efficient way to add links to PDF pages, whether leading to resources in another PDF or for extracting existing links and modifying them. Here’s how to get started.

Step 1: Install PyMuPDF

Before you can use PyMuPDF, you need to install it. This can be easily done using pip. Run the following command in your command line or terminal:
