Pinpointing the Differences between Two PDF Files
Explore how to create a Python utility that compares two PDF documents by converting pages to images and highlighting differences. Understand the use of key libraries to automate PDF comparison, enabling efficient proofreading and content verification.
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.
