# @ohos.sendableResourceManager (Resource Manager)

The **sendableResourceManager** module provides the [resourceToSendableResource](#sendableresourcemanagerresourcetosendableresource) and [sendableResourceToResource](#sendableresourcemanagersendableresourcetoresource) APIs to implement conversion between [Resource](#resource) and [SendableResource](#sendableresource) objects.

A **Resource** object can be held by the [Sendable](../../arkts-utils/arkts-sendable.md) class after being converted into a **SendableResource** object. After cross-thread transmission, the **Sendable** class converts the **SendableResource** object into a **Resource** object and uses it as an input parameter for the API used to obtain resources.

> **NOTE**
>
> The initial APIs of this module are supported since API version 12. Newly added APIs will be marked with a superscript to indicate their earliest API version.
