Bun provides a number of convenience functions for reading the contents of a [`ReadableStream`](https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream) into different formats.

```ts
const stream = new ReadableStream();
const blob = await Bun.readableStreamToBlob(stream);
```

See [Docs > API > Utils](/docs/runtime/utils#bun-readablestreamto) for documentation on Bun's other `ReadableStream` conversion functions.
