<Callout type="info" title="Note">
  LibreChat supports local storage, object storage backends, and CDN-backed delivery. Use an object
  storage backend such as S3 or Azure Blob Storage for durable file storage, then add a CDN like
  CloudFront when you need stable media links, edge caching, signed cookies, or signed download URLs.
