+### Delete media uploaded by a user
+
+This API deletes the *local* media from the disk of your own server
+that a specific `user_id` has created. This includes any local thumbnails.
+
+This API will not affect media that has been uploaded to external
+media repositories (e.g https://github.com/turt2live/matrix-media-repo/).
+
+By default, the API deletes media ordered by descending creation date and ascending media ID.
+The newest media is deleted first. You can change the order with parameters
+`order_by` and `dir`. If no `limit` is set the API deletes `100` files per request.
+
+The API is:
+
+```
+DELETE /_synapse/admin/v1/users/<user_id>/media
+```
+
+To use it, you will need to authenticate by providing an `access_token` for a
+server admin: [Admin API](../usage/administration/admin_api)
+
+A response body like the following is returned:
+
+```json
+{
+  "deleted_media": [
+    "abcdefghijklmnopqrstuvwx"
+  ],
+  "total": 1
+}
+```
+
+The following fields are returned in the JSON response body:
+
+* `deleted_media`: an array of strings - List of deleted `media_id`
+* `total`: integer - Total number of deleted `media_id`
+
+**Note**: There is no `next_token`. This is not useful for deleting media, because
+after deleting media the remaining media have a new order.
+
+**Parameters**
+
+This API has the same parameters as
+[List media uploaded by a user](#list-media-uploaded-by-a-user).
+With the parameters you can for example limit the number of files to delete at once or
+delete largest/smallest or newest/oldest files first.
