# Upload creatives

> Upload your creatives in the Unity User Acquisition Dashboard to use them in your campaigns.

Creatives are the ad assets of an advertising campaign. Creatives consist of images, videos, or other rich media formats.

You can upload your creatives in advance to keep them organized in the [Unity User Acquisition Dashboard](http://cloud.unity.com) before you start to make creative packs.

For more information, refer to [Introduction to User Acquisition creatives](/user-acquisition/creatives/intro-to-creatives.md).

## Prerequisites

Before you upload your creatives, ensure that they meet the required creative specifications.

## Upload creatives in the User Acquisition Dashboard

To upload creatives, follow these steps from the **Creative library** page:

1. Go to the **Creatives** tab.

2. Select **Upload creatives**.

3. Select the app you want to upload creatives for.

4. Browse and select all the desired creatives. After you select them, they are listed in the **Upload creatives** screen.

5. Assign a moderation **language** to the creatives to ensure they go to a human moderator who speaks that language. A human moderator reviews the creative. For more information, refer to Introduction to moderation.

   1. **Assign language in bulk**

      Select the language and then select **Assign all**.

   2. **Assign language to individual creatives**

      Next to each creative, select the language.

6. Select **Upload**.

Creatives go through human creative moderation to ensure they follow the [Unity Advertising Services Content Policy](https://unity.com/legal/content-policy) and to receive an age rating. You can consult the status under the **Moderation** column of the creatives table. To receive an email notification when the review is complete, enable **Creative moderation alerts** in the dashboard settings.

Next, you can start to [make creative packs](/user-acquisition/creatives/make-creative-packs.md).
