  title: Supabase Storage Rendering API
  description: The Supabase Storage API enables developers to store, organize, and serve large files such as images, videos, and documents. It provides bucket-based organization with support for uploading, downloading, and transforming files including on-the-fly image resizing and optimization. Access control is managed through Row Level Security policies tied to the PostgreSQL database. The API supports both public and private storage buckets, resumable uploads via the TUS protocol, and S3-compatible access.
