Storage Usage
View storage usage summary with file counts and size breakdown by category.
Overview
The Storage Usage summary provides an at-a-glance view of how your storage bucket is being used. See total file counts, sizes, and a breakdown by content category. This works across all providers — Firebase Cloud Storage, Supabase Storage, and Amazon S3.
Usage Summary Panel
The usage summary appears as a collapsible panel when files are loaded in the storage browser. It shows:
- Total File Count — the number of files in the current bucket
- Total Size — the aggregate size of all files
- Category Breakdown — file counts and sizes grouped by content type
Categories
Files are grouped into the following categories based on their content type:
Images
All files with image/* content types, including JPEG, PNG, GIF, WebP, and SVG. This typically represents the largest category for apps with user-generated content.
Videos
All files with video/* content types, including MP4, MOV, and WebM. Video files often account for the most storage space due to their large file sizes.
Audio
All files with audio/* content types, including MP3, WAV, and AAC.
Documents
Text files, PDFs, JSON, XML, and other document types. This includes text/* content types as well as common document MIME types like application/pdf and application/json.
Other
Everything that does not fit the above categories, such as binary files, archives, and files with unrecognized content types.
Display
Each category shows:
- The number of files in that category
- The total size for that category (formatted as KB, MB, or GB)
- A proportional bar or size indicator
Categories are sorted by total size in descending order, so the largest category appears first.
Use Cases
- Budget planning — understand your storage consumption to estimate costs
- Cleanup — identify large categories that may contain unused files
- Monitoring — track storage growth over time by periodically checking the summary
- Optimization — find categories where compression or cleanup would save the most space
Tips
- The usage summary reflects the files currently visible in the browser. Navigate to the root to see bucket-wide statistics.
- Large video files are often the biggest cost driver. Consider using a CDN or external video hosting if storage costs are high.
- Regularly review the “Other” category for files that may have incorrect or missing content types.
