# Convert a ReadableStream to a Blob

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

```ts theme={null}
const stream = new ReadableStream();
const blob = await Bun.readableStreamToBlob(stream);
```
