# Resize a volume

Volumes can be resized as needed.

## Resize a volume using the control panel

It's possible to resize a volume, both upward and downward. At the top of the page for the current volume, click **Actions** and then **Change plan**.

In the dialog box that appears, select a new size for the volume and then click **Update Settings**. Here, you can also enable or disable automatic upgrade of the volume.

## Resize a volume using the API

Use the [filestorage/listplans](https://github.com/GleSYS/API-docs/wiki/API-Documentation#filestoragelistplans) endpoint to list available plans, then [filestorage/editvolume](https://github.com/GleSYS/API-docs/wiki/API-Documentation#filestorageeditvolume) to change the plan, i.e., resize the volume.

For general instructions on how to use the API, see [Platform → API](/platform/control-panel/api.md).
