## NAME
podman-image-prune - Remove all unused images from the local store

## SYNOPSIS
**podman image prune** [*options*]

## DESCRIPTION
**podman image prune** removes all dangling images from local storage. With the `all` option,
you can delete all unused images (i.e., images not in use by any container).

The image prune command does not prune cache images that only use layers that are necessary for other images.

## OPTIONS
#### **--all**, **-a**

Remove dangling images and images that have no associated containers.

#### **--external**

Remove images even when they are used by external containers (e.g., build containers).

#### **--filter**=*filters*

Provide filter values.

The *filters* argument format is of `key=value`. If there is more than one *filter*, then pass multiple OPTIONS: **--filter** *foo=bar* **--filter** *bif=baz*.

Supported filters:

| Filter             | Description                                                                 |
| :----------------: | --------------------------------------------------------------------------- |
| *label*            | Only remove images, with (or without, in the case of label!=[...] is used) the specified labels.                  |
| *until*            | Only remove images created before given timestamp.           |


The `label` *filter* accepts two formats. One is the `label`=*key* or `label`=*key*=*value*, which removes containers with the specified labels. The other format is the `label!`=*key* or `label!`=*key*=*value*, which removes containers without the specified labels.

The `until` *filter* can be Unix timestamps, date formatted timestamps or Go duration strings (e.g. 10m, 1h30m) computed relative to the machine’s time.

#### **--force**, **-f**

Do not provide an interactive prompt for container removal.

#### **--help**, **-h**
