Comparing two Word documents side-by-side is required for many scenarios. You may have two versions of a business proposal, one written by you and the other updated by your colleague. So, you want to look at what changes your colleague made. Similarly, you may want to compare draft and final versions of reports, different versions of a contract, and similar others.
It is now easier than ever to compare two Word documents. In this guide, we present two ways to compare and spot differences between the two Word documents autonomously.
Part 1. How Do I Compare Two Word Documents for Differences? - The Default Method
Microsoft Word has a built-in "Compare" feature that allows you to compare 2 Word documents for differences. It will automatically detect the changes in the content. It can compare changes in text, images, tables, formatting, headers/footers, fields, and more. Furthermore, you can view the differences within the original/revised document or generate a new comparison document.
Follow the below steps to learn how to compare two Word documents using the default method:
Step 1. Launch Word and open a new blank document.
Step 2. Under the "Review" tab from the top, click Compare > Compare….
Step 3. A pop-up window of Compare Documents will appear. Here, select the original and revised documents. Also enter the writer's name in the "Label changes with" to better distinguish the changes.

That's it! You will notice Word instantly providing a detailed comparison of two documents. Furthermore, it will have synchronized scrolling to visualize changes easily. This way, you can compare two Word documents directly from Microsoft Word.
