To compare the differences between two Word documents, use Word's built-in "Compare" feature or online tools. First, use the "Compare Document" function in the "Review" tab of Word to select the original and revised documents to generate comparison results, which can clearly display changes such as text addition and deletion, format adjustment, and support item-by-item acceptance or rejection of changes; secondly, if the full version of Word is not installed, you can upload files to automatically compare files such as Diffchecker, WordHacker, Docx Compare and other online tools to upload files to automatically compare, but you need to pay attention to the risk of sensitive information leakage; finally, when checking format differences, you can view paragraph settings and font parameters through the "Style Checker" and selected content to ensure the unified layout to improve the professionalism of the document.
Sometimes you need to compare two Word documents to find out the differences, such as modifying content, format changes, or adding new deleted parts. Direct comparison of naked eyes is not only time-consuming and easy to make mistakes. In fact, there are some ways to help you complete this task more efficiently.

Use Word's built-in "Compare" feature
Microsoft Word comes with a very practical feature called Compare, which can automatically mark the differences between two documents.

The operation steps are as follows:
- Open Word and click the "Review" tab
- Select Compare > Compare Documents
- Browse and select original and revised documents
- Click "OK", Word will generate a new document that displays all the changes
The advantage of this function is that it can clearly mark changes such as text addition and deletion, format adjustment and even paragraph movement. You can also accept or reject changes item by item under the Review tab.

Note: This feature is suitable for documents that have "Tracking Changes" enabled. If neither document has been tracked, the results may be less accurate.
Use the online comparison tool
If you don't have the full version of Word installed, or want to complete the comparison faster, you can use some online tools. These tools usually support uploading two .docx files and then automatically generate comparison results.
Common tools include:
- Diffchecker
- WordHacker
- Docx Compare
The operation of these tools is very simple. Basically, it is to upload two files and click the "Compare" button. Some tools also use color highlighting differences and retain the original text format.
However, it should be noted that uploading sensitive documents to online platforms may be at risk of leakage. It is recommended to delete the cloud backup in time after processing.
View small differences in format
Sometimes the text content of the two documents is similar, but the layout looks different. This may be a nuance in formats such as font, line spacing, indentation, etc.
To check for such differences, try the following:
- Use Word's "Style Checker" function to see if the styles used in each paragraph are consistent.
- Press Ctrl A to select all contents, open the "Paragraph" setting window, and compare the parameters
- Observe whether the font, font size and color are uniform in the "Start" menu
Format issues are not easy to see at a glance, but they will affect the professionalism of the document, especially when used for reporting or publishing, details are particularly important.
Basically these are the methods. You can choose to use Word's own features or online tools according to your own situation. If it is a formal purpose, remember to pay more attention to the differences in formats.
