Visually Compare by Arranging Two Publisher Windows

Since Publisher does not have a native comparison tool, you can manually open two instances of the application and snap the windows side by side.

While Microsoft Word allows you to automatically compare and merge documents, Publisher requires a manual visual review. Opening the files in separate application windows lets you utilize your operating system's window management features to view them simultaneously.

1
Open the first document

Launch Microsoft Publisher and open your first publication file.

2
Open a second instance of Publisher

Right-click the Microsoft Publisher icon on your taskbar and select 'Microsoft Publisher' to open a completely separate application window, then open your second publication in this new window.

3
Arrange windows side by side

Click and drag the title bar of the first Publisher window to the left edge of your screen until it snaps into place. Repeat this process by dragging the second Publisher window to the right edge of your screen.

Frequently Asked Questions

Does Microsoft Publisher have a built-in 'Compare Documents' feature?

No, unlike Microsoft Word, Microsoft Publisher does not currently include a native document comparison or merge feature. You must manually arrange two application windows side by side to review differences.

Can I use synchronous scrolling when comparing Publisher files?

Because Publisher lacks a built-in side-by-side view mode, synchronous scrolling is not natively supported. You will need to manually scroll through each window independently while comparing your documents.

Why won't my second Publisher document open in a new window?

If you open a document from within an already running instance of Publisher, it may replace the current view or open in a new tab depending on your settings. To ensure it opens in a separate window for side-by-side comparison, launch a fresh instance of the Publisher application from your taskbar or start menu first, then open the file.
