## NAME

## SYNOPSIS
**podman save** [*options*] *name*[:*tag*]

## DESCRIPTION
**podman save** saves an image to a local file or directory.
**podman save** writes to STDOUT by default and can be redirected to a

**podman save** will save parent layers of the image(s) and the image(s) can be loaded using **podman load**.
To export the containers, use the **podman export**.
Note: `:` is a restricted character and cannot be part of the file name.
