- Product
- Microsoft Word Online
- Device & OS
- not provided
- Scenario
- Viewing or editing a document that contains mathematical equations within a web browser using Word Online.
- Observed behavior
- Equations do not render visually on the screen and instead appear as gray placeholder boxes, even though they print correctly and remain fully intact within the document.
Ensure your browser is up to date and try clearing your browser cache, as online document rendering issues are frequently caused by temporary service glitches or outdated browser data.
Switch to Reading View to Display Equations
Changing your document view mode can often bypass Editing view rendering limitations, allowing equations to display properly.
Historically, Word Online has struggled with rendering complex formatting like equations while in Editing view due to browser limitations. Switching to Reading view processes the document differently and usually renders the equations correctly.
Open your document in Word Online and click on the 'View' tab located in the top ribbon menu.
Click on 'Reading View'. The document will reload in a view-only mode, and the gray "[Equation]" boxes should now render as proper mathematical equations.
Open the Equation Editor Manually
If you need to edit the grayed-out equation, you can still access its contents by launching the equation editor directly.
Open the Document in the Desktop App
Transitioning to the desktop version of Word ensures full rendering capabilities without browser restrictions.
Edit Equations Seamlessly with WPS Office
Tired of web browser limitations and rendering glitches? Switch to WPS Office, a free and lightweight desktop alternative that natively supports complex equations and formatting without missing a beat.
- 1. Download WPS Office: Visit the official WPS website and download the free WPS Office suite for your operating system.
- 2. Open Your Document: Launch WPS Writer and open your DOCX file directly to see all equations rendered accurately.

Frequently Asked Questions
Will these grayed-out equations print correctly if I print from Word Online?
Yes, even if the equations display as gray "[Equation]" boxes on your screen while editing, they will usually render perfectly when you print the document or export it as a PDF.
Why does Word Online struggle to display equations?
Word Online is a lighter, browser-based version of the desktop software. Rendering complex mathematical typography in a web browser during active editing requires heavy processing, which sometimes causes display glitches or is disabled by design during service updates.
How can I report this rendering bug to Microsoft?
You can report the issue directly from Word Online by clicking on 'Help' in the top ribbon and selecting 'Feedback'. Describe the issue and mention your browser and OS to help them track the bug.
