Cloud Storage for Firebase

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.

Key capabilities

Robust operations 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.
Secure your Files Use Firebase Security Rules for Cloud Storage to secure your files.
(Optional) Create and Share Download URLs Use the Firebase Admin SDK to generate shareable URLs to let users download objects.
