Question details
The user is seeing alternating white and black squares in the background of their PDF files in Adobe Acrobat and wants to know how to fix it and whether it affects online publishing.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Viewing PDF files locally in Adobe Acrobat and preparing them to be published online.
- Observed behavior
- PDF files display a checkerboard pattern of alternating white and black squares in the background unless manually changed, causing concern about how website visitors will view the file.
Before altering any software settings, try opening the exact same PDF file in a standard web browser like Chrome or Edge to confirm whether the squares are actually embedded in the file or just a local display setting in Acrobat.
Disable the Transparency Grid and Reset Preferences
The checkerboard pattern usually represents a transparency grid in Acrobat rather than actual document content. Disabling it or resetting your display preferences will resolve the visual issue.
In Adobe products, a grid of black and white squares indicates transparent areas of a document. If your PDF does not have a solid background color set, Acrobat may display this grid by default depending on your preferences.
Open Adobe Acrobat. Navigate to 'Edit' > 'Preferences' on Windows, or 'Acrobat' > 'Preferences' on a Mac.
In the left-hand menu pane of the Preferences window, click on the 'Page Display' category.
Look under the 'Page Content and Information' section and uncheck the box labeled 'Show transparency grid'. Click 'OK' to apply the changes.
Open the PDF file in a completely different program, such as your default web browser, to confirm the squares do not appear for standard viewers.
Update Adobe Acrobat to Resolve Rendering Bugs
If the squares persist despite changing transparency settings, you may be experiencing a rendering glitch that can be fixed by updating the application.

Frequently Asked Questions
Why does my PDF have a checkerboard background?
A checkerboard or alternating white and black square pattern visually represents a transparent background in Adobe applications. It is an internal visual aid to help editors identify areas with no background color.
Will the black and white squares show up when I print the document?
No, the transparency grid is strictly a display setting within your PDF editing software. When printed, those transparent areas will simply adopt the color of the paper.
How do I add a solid white background to my PDF?
In Adobe Acrobat, you can apply a solid background by navigating to 'Tools' > 'Edit PDF' > 'More' > 'Background' > 'Add'. Choose white from the color palette to apply a solid color behind your document content.
Does viewing the PDF in a web browser accurately show what visitors will see?
Yes, opening your PDF in browsers like Google Chrome or Microsoft Edge gives you an accurate representation of how the document will render for the vast majority of online users, since most will use built-in browser viewers.
