Changing folder thumbnails in Windows 11 helps you spot projects and apps at a glance. With a few clicks, you can replace the default icon grid with a custom image that reflects your workflow or brand.
Use this guide to manage thumbnails for any folder without third-party tools and keep your workspace organized and visually consistent.
| Action | Setting Location | Default | After Change |
|---|---|---|---|
| Open folder properties | Right-click folder → Properties | Standard icon | Prepares thumbnail customization |
| Browse custom image | Customize tab → Change icon → Browse | System icons only | Any .ico or .png file |
| Apply thumbnail | Select image → OK → Apply | Generic view | Folder-specific preview |
| Revert to default | Restore Defaults in Properties | Custom thumbnail | Windows standard icon |
Access folder properties to prepare for thumbnail change
Begin by opening the folder you want to personalize. Right-click the folder on the desktop, in File Explorer, or from Quick Access and choose Properties. The Properties dialog gives you access to appearance settings, including the Customize tab where thumbnail assignment happens.
Navigate to the customize tab for thumbnail settings
Inside Properties, click the Customize tab to reveal options for folder icon and thumbnail behavior. This is the central place for swapping the default folder icon with a custom image stored on your device.
Browse and select your preferred image file
Click Change Icon, then select Browse to locate an .ico, .png, or other image file. Make sure the image is clear at small sizes, since Windows scales thumbnails to folder view resolutions.
Confirm and apply the new thumbnail
After choosing an image, click OK to register it in the Change Icon dialog, then press Apply in the Properties window. Windows updates the folder thumbnail immediately in the current view and for future sessions.
Organize folders with consistent thumbnail appearance
To maintain a coherent look across projects, apply the same custom thumbnail style to related folders. Consistent visuals make it faster to identify work areas, content libraries, and shared resources at a glance.
Troubleshoot common thumbnail display issues
If the thumbnail does not update, try refreshing the view by pressing F5 or switching to another folder and back. Restarting File Explorer from Task Manager can also clear cached icon data when changes do not appear.

FAQ
Reader questions
Why does my custom folder thumbnail not show after I apply it?
Windows may be caching the old icon; refresh the view with F5 or restart File Explorer from Task Manager to force a reload of thumbnail data.
Can I use a JPEG or PNG file directly as a folder thumbnail?
Windows expects an icon format, so convert your image to .ico or use an existing icon file. Some third-party tools can embed PNG resources, but native support is limited to icon files.
Will changing the folder thumbnail affect the folder contents or permissions?
No, thumbnail customization only updates the visual representation. File contents, access permissions, and folder properties remain unchanged.
How do I revert my folder to the default Windows icon?
Open Properties → Customize tab → Restore Defaults, or click Change Icon and select a standard system icon to restore the original look.
