Pinpointing the Differences between Two PDF Files

Learn to compare PDF documents using Scikit-image, PyMuPDF, OpenCV, and Pillow Python libraries.

Introduction

Quite often, we’ll need to proofread a large and critical PDF document to quickly and reliably identify the differences between two versions, such as evaluating a contract against an older version of the same contract.

In such situations, we tend to get stuck and resort to manual checking by opening both documents side by side, and comparing them page by page.

This painstaking verification process becomes increasingly difficult if we can’t pinpoint exactly what was changed, especially when the document has many pages.

If you’re unsure and are seeking an efficient solution to matching two PDF files, then this lesson will help you learn an easy method to do it.

Scope

This lesson will give us guidance on the steps required to develop a PDF comparison utility while relying on the capabilities of the Python programming language.

With this customized utility, it’s just a matter of specifying the PDF files to compare without drowning in the manual verification problem.
