Quickstart: Upload, download, and list blobs using the Azure portal

In this quickstart, you learn how to use the Azure portal to create a container in Azure Storage, and to upload and download block blobs in that container.


If you don't have an Azure subscription, create a free account before you begin.

Create a storage account by using the Azure portal

First, create a new general-purpose storage account to use for this quickstart.

  1. Go to the Azure portal and sign in by using your Azure account.
  2. Enter a unique name for your storage account. Keep these rules in mind for naming your storage account:
    • The name must be 3 to 24 characters in length.
    • The name can contain numbers and lowercase letters only.
  3. Select your subscription.
  4. Create a new Resource group and give it a unique name.
  5. Select the Location to use for your storage account.
  6. Leave other fields set to their default values.
  7. Select Pin to dashboard and select Create to create your storage account.

After your storage account is created, it's pinned to the dashboard of the Azure portal. Select the storage account to open it. Under Settings, select Access keys. Select the primary account access key and click the Copy button to copy the associated connection string to the clipboard. Then paste the string into a text editor for later use.

Create a container

To create a container in the Azure portal, follow these steps:

  1. Navigate to your new storage account in the Azure portal.
  2. In the left menu for the storage account, scroll to the Blob Service section, then select Browse Blobs.
  3. Click the Add Container button.
  4. Enter a name for your new container. The container name must be lowercase, must start with a letter or number and can contain only letters, numbers, and the dash (-) character. See Naming and Referencing Containers, Blobs, and Metadata for more information about container and blob names.
  5. Set the level of public access to the container. The default level is Private (no anonymous access).
  6. Click OK to create the container.

Upload a block blob

Block blobs consist of blocks of data assembled to make a blob. Most scenarios using Blob storage employ block blobs. Block blobs are ideal for storing text and binary data in the cloud, like files, images, and videos. This quickstart shows how to work with block blobs.

To upload a block blob to your new container in the Azure portal, follow these steps:

  1. In the Azure portal, navigate to the container you created in the previous section.
  2. Select the container to show a list of blobs it contains. In this case, since you created a new container, it won't yet contain any blobs.
  3. Click the Upload button to upload a blob to the container.
  4. Browse your local file system to find a file to upload as a block blob, and click Upload.

  5. Upload as many blobs as you like in this way. You'll see that the new blobs are now listed within the container.

Download a block blob

You can download a block blob to display in the browser or save to your local file system. To download a block blob, follow these steps:

  1. Navigate to the list of blobs that you uploaded in the previous section.
  2. Select the blob to download.
  3. Right-click the More button (...), and select Download.

Clean up resources

To remove the resources you created in this quickstart, you can simply delete the container. All blobs in the container will also be deleted.

To delete the container:

  1. In the Azure portal, navigate to the list of containers in your storage account.
  2. Select the container to delete.
  3. Right-click the More button (...), and select Delete.
  4. Confirm that you want to delete the container.
