# SYNOPSIS
**podman image prune**
+[**-a**|**--all**]
[**-h**|**--help**]
# DESCRIPTION
-**podman image prune** removes all unused images from local storage. An unused image
-is defined as an image that does not have any containers based on it.
+**podman image prune** removes all dangling images from local storage. With the `all` option,
+you can delete all unused images. Unused images are dangling images as well as any image that
+does not have any containers based on it.
+
+## OPTIONS
+**--all, -a**
+
+Remove dangling images and images that have no associated containers.
## Examples ##
-Remove all unused images from local storage
+Remove all dangling images from local storage
