Convex file uploads require generating a short-lived upload URL on the server, sending the file from the React client, and persisting the resulting storage ID in your database. This workflow ensures secure file uploads by decoupling the transfer from your API routes.

Retrieve stable file URLs for serving images, PDFs, and downloads by querying your database for the storage ID. Convex generates a URL that allows users to view or access stored content directly from the client without exposing your backend storage layer.

The best way to delete files in Convex is to remove the file from storage and simultaneously delete its database reference. This cleanup process prevents orphaned storage records and ensures your database metadata stays synchronized with your actual file storage.

Yes, Convex file storage supports storing generated files and inspecting their metadata. You can retrieve content-type information and storage metadata to verify file properties before serving them to users or applying further processing logic.

Manage content-type handling by inspecting storage metadata after the upload completes. Convex tracks the content-type sent during the client-side upload, allowing you to validate image, document, and generated-file formats before persisting the database reference.
