# Media library

Store and manage image, audio, and video content for your messages. You can preview each file and assign keywords so they are easily found in search.

## About the media library

Use the media library to host media files for your project and insert them when you compose messages, without uploading the same asset every time.

Your Airship plan must include [CDN](https://en.wikipedia.org/wiki/Content_delivery_network) support to use the media library. [Contact Support](https://support.airship.com/) if you are interested in enabling CDN media hosting.

File guidelines and handling:

* Uploaded media must be 2 MB or smaller.
* You can upload up to 100 files at a time.
* There are no restrictions on uploading identical files or files with identical names.
* The media library is not available for MMS messages.
* Media that is not accessed by end users is automatically removed according to the [Airship Data Retention Schedule](https://www.airship.com/docs/reference/general/#data-retention-schedule).
