Isolate the File and Rebuild to Clear Corruption

Determine if the issue is isolated to a single file and manually move content to a fresh publication to eliminate underlying file corruption.

Often, random formatting changes are confined to a single corrupted document rather than the application itself. Testing with a new file helps isolate the problem.

1
Create a test publication

Open a completely new, blank Publisher document and type out some test text with formatting to see if the random changes occur.

2
Copy content in sections

If the new file works perfectly, open your corrupted file. Copy the content section by section (such as individual text boxes or images) and paste it into the new document.

3
Test after pasting

Observe the formatting in the new document after pasting each section to identify which specific element or text box is triggering the formatting glitch.

Tip: Pasting text without formatting (using the 'Keep Text Only' paste option) can help strip away corrupted hidden styles.

Frequently Asked Questions

Why does Publisher keep changing my font size automatically?

This is often caused by the AutoFit Text feature. To fix it, right-click the text box, select 'Format Text Box', navigate to the 'Text Box' tab, and change the AutoFit Text setting to 'Do not Autofit'.

Can a corrupted font file cause random formatting changes?

Yes. If a downloaded or non-standard font is corrupted, Publisher may struggle to render it correctly, resulting in random substitutions, capitalization errors, or resizing. Switching back to a standard system font like Arial can resolve this.

How do I know if my Publisher file is corrupted?

If random formatting changes only happen in one specific document while newly created blank files work perfectly fine, the original file is likely corrupted. Rebuilding the document by selectively pasting content into a new file is the most effective solution.
