Enable PDF thumbnail preview in Windows 10

Adobe Acrobat Reader DC version installed on Windows 10 PC’s sometimes doesn’t show PDF thumbnails in the Windows Explorer and only the default file icon is visible.

If you are using Adobe Acrobat Reader DC and can’t see the thumbnail preview of the PDF files in the file explorer then you would have to enable it within the Acrobat Reader preferences.

Steps to Enable Thumbnail Preview for PDF files

Note: If you have an older version of Adobe Acrobat reader then update to the latest version from the following link.

Open the Acrobat Reader DC. Go to the Edit Menu and Choose Preferences. Or, you can Press Ctrl+K to open Preferences

In the left side Categories panel, select General from the list. Select the Enable PDF thumbnail previews in Windows Explorer check box

Scroll down and click on OK. Acrobat Reader would ask for your confirmation to install a feature. Click on Yes.

This would enable the PDF thumbnail preview in the File Explorer.

Alternatively, You can also Preview PDF Files using the File Explorer preview pane. Windows File preview lets you open  the file preview in a side panel.

To quickly enable the File Preview you can press the shortcut ALT + P or you can enable it from the top Ribbon menu in Filer Explorer. To enable it Go to View menu and click on Preview Pane.
