# Save a document to a remote server in Flutter

Since version 3.10, Nutrient Flutter SDK allows you to export PDFs in raw binary data format. This can be done using the `exportPdf` method from the [`PdfDocument`](https://pub.dev/documentation/nutrient_flutter/latest/nutrient_flutter/PdfDocument-class.html) class. With this method, you can save data to a file or upload it to a remote server.

Here’s an example of how to export a PDF to Base64 data:

```dart

pdfDocument.exportPdf().then((Uint8List data) {
    /// Convert the data to a Base64 string.
    base64Data = base64Encode(data);
    /// Upload the data to a remote server.
    http.post('https://example.com/upload', body: base64Data);
});

```
