Cloud Storage for Firebase is built on fast and secure
Google Cloud infrastructure for app developers who need to store and serve
user-generated content, such as photos or videos.
Cloud Storage for Firebase is a powerful, simple, and cost-effective object
storage service built for Google scale. The Firebase SDKs for Cloud Storage add Google
security to file uploads and downloads for your Firebase apps, regardless of
network quality.
You can use our client SDKs to store images, audio, video, or other
user-generated content. On the server, you can use the Firebase Admin SDK to
manage buckets and create download URLs, and use
Google Cloud Storage APIs
to access your files.
Firebase SDKs for Cloud Storage perform uploads and downloads regardless of
network quality. Uploads and downloads are robust, meaning they restart where
they stopped, saving your users time and bandwidth.
Strong security
Firebase SDKs for Cloud Storage integrate with Firebase Authentication to provide
simple and intuitive authentication for developers. You can use our
declarative security model to allow access based on filename, size, content
type, and other metadata.
High scalability
Cloud Storage is built for exabyte scale when your app goes viral.
Effortlessly grow from prototype to production using the same infrastructure
that powers Spotify and Google Photos.
How does it work?
Developers use the Firebase SDKs for Cloud Storage to upload and download files
directly from clients. If the network connection is poor, the client is able to
retry the operation right where it left off, saving your users time and
bandwidth.
Cloud Storage for Firebase stores your files in a
Google Cloud Storage bucket,
making them accessible through both Firebase and Google Cloud. This allows you
the flexibility to upload and download files from mobile clients via the
Firebase SDKs for Cloud Storage. In addition, you can do server-side processing such
as image filtering or video transcoding using the
Google Cloud Storage APIs.
Cloud Storage scales automatically, meaning that there's no need to
migrate to any other provider. Learn more about all the benefits of our
integration with Google Cloud.
The Firebase SDKs for Cloud Storage integrate seamlessly with
Firebase Authentication to identify users, and we provide a
declarative security language that lets you set
access controls on individual files or groups of files, so you can make files as
public or private as you want.
Implementation path
Integrate the Firebase SDKs for Cloud Storage.
Quickly include clients via Gradle, CocoaPods, or a script include.
Create a Reference
Reference the path to a file, such as "images/mountains.png", to upload,
download, or delete it.
Upload or Download
Upload or download to native types in memory or on disk.
Firebase Remote Config stores developer-specified
key-value pairs to change the behavior and appearance of your app without
requiring users to download an update.
Firebase Hosting hosts the HTML, CSS, and
JavaScript for your website as well as other developer-provided assets like
graphics, fonts, and icons.
Next steps
Upload your first file to Cloud Storage using our quickstarts for
iOS,
Android,
Web,
C++,
or Unity.
