# Storage

> Store and serve large binary files.

Use InsForge to store and serve large binary files: images, videos, PDFs, audio, backups, anything you would not put in a database row. Every project gets an S3-compatible bucket. Files are served behind signed URLs, access policies follow the same row-level security model as the database, and the S3 API works with rclone, the AWS CLI, Terraform, and SDKs in any language.

<Note>
  **Looking for structured data?** Use [Database](/core-concepts/database/overview) for rows, relations, and queries. Storage holds objects; the database holds rows. Keep file metadata (owner, name, size, content type) in a database table and the bytes in storage.

## Features

### S3-compatible API

Point any S3 client at your project's bucket. Native AWS credentials, native multipart uploads, native presigned URLs. See [S3 compatibility](/core-concepts/storage/s3-compatibility).

### Signed URLs

Generate time-limited URLs to share private objects without exposing your credentials. The SDK and REST API both issue signed URLs for upload and download.

### Row-level security

Storage policies read the same auth JWT as database queries. The same user who can `SELECT` a row can `GET` the file the row references, so you never maintain a separate set of storage permissions.

### Buckets

Group objects into buckets with separate access policies. Public buckets serve files directly over HTTPS; private buckets require a signed URL or an authenticated request.

### Direct uploads

Browser and mobile clients upload straight to storage with a presigned URL. The backend never proxies bytes.
