How to Save a Word Document Created by Compare

Product: Microsoft Word
Device & OS: not provided
Scenario: Trying to save a comparison document that highlights the differences between an original and a revised file.
Observed behavior: The document either refuses to save, or when successfully saved as a separate file, it displays absolutely no content and opens blank.

Before you start

Verify that both your original and revised source files are completely closed in other programs, and ensure neither file is set to 'Read-only' or protected with an editing password before you begin.

Solution 1Recommended

Create and Save the Comparison to a Local Drive

Start fresh and save the comparison output directly to your local computer rather than a cloud-synced folder to prevent saving errors.

Saving directly to cloud environments like OneDrive or SharePoint during a heavy processing task like document comparison can sometimes cause file corruption or blank saves. Saving locally bypasses this sync interruption.

Open Word without documents

Launch Microsoft Word from your Start menu without opening any existing documents.

Run the compare tool

Navigate to the Review tab, click on Compare, and select Compare... from the drop-down menu.

Set output to a new document

Choose your original and revised files. Under the 'Show changes in' section, ensure the radio button is set to New document, then click OK.

Save immediately to a local folder

As soon as the comparison document is generated, go to File > Save As (or Save a Copy). Select a local directory such as your Documents or Desktop folder, and click Save.

Create and Save the Comparison to a Local Drive

Local Storage: Once the file is safely saved to a local drive, you can safely copy or move it to your preferred cloud storage folder later.

Solution 2

Copy the Comparison Content into a Blank Document

If the generated comparison file is glitching and won't save correctly, manually copying the text to a fresh document can bypass the restriction.

Solution 3

Update Office or Opt Out of Insider Builds

Beta or Insider Preview builds of Microsoft Word frequently contain bugs that cause newly generated documents, like comparisons, to save as blank pages.

Frequently Asked Questions

Why does my Word compare document open as a blank page?

This usually happens if the source files have restrictive permissions, if the generated file was saved directly to a cloud sync folder experiencing interruptions, or due to a known glitch in certain Office Insider Preview builds.

How can I check if my source documents are read-only?

Right-click the original and revised files in Windows File Explorer, select Properties, and look at the Attributes section at the bottom of the General tab. Make sure the Read-only checkbox is unchecked.

Can I compare a protected document?

If a document is protected with a password or strict editing restrictions, you will likely encounter errors. You must remove the protection first by going to Review > Restrict Editing and clicking Stop Protection before running the comparison.

Where is the best place to save a newly compared document?

To ensure the document saves correctly without corruption, it is highly recommended to immediately save the output file to a local drive (like your Desktop or local Documents folder) rather than directly saving it into a synced OneDrive or SharePoint folder.
