Save a PDF to a Remote Server in MAUI

Saving a PDF document to a server in MAUI is achievable by programmatically exporting the document and then sending it to its remote destination.

Note that there’s a platform-specific setup required for FileSaver. It’s worth reading about the setup here if you’re not familiar with it.

Exporting a Document to a Remote Server

The example below uses Microsoft’s HttpClient for demonstration purposes, though the general idea can be adapted to whichever solution you use:

HttpClient client = new HttpClient();

MultipartFormDataContent form = new MultipartFormDataContent();

var exportConfiguration = _document.CreateExportConfiguration();
// Update the configuration here.

// Read the file into a byte array.
byte[] fileBytes = await _document.ExportDocumentAsync(exportConfiguration);

// Create a `ByteArrayContent` from the byte array.
ByteArrayContent fileContent = new ByteArrayContent(fileBytes);

// Add the file content to the form.
form.Add(fileContent, "file", "download.pdf");
form.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
    FileName = "download.pdf"

// Send the `POST` request to the server.
HttpResponseMessage response = await client.PostAsync(remoteLocation, form);

// Check the response status.
if (response.IsSuccessStatusCode)
    // File uploaded successfully.
    Console.WriteLine("File uploaded successfully");
    // File upload failed.
    Console.WriteLine("File upload failed. Status: " + response.StatusCode);

For more control over exporting documents, use IExportConfiguration. If you pass null instead, the default configuration will be used.

To make it easier to try exporting a document to a remote server in Catalog, we added a Python script,, which can be used to start a local server. You can find it in the Resources/Server/ folder. To start the server:

  1. Install Python.

  2. Run the server using the python command.

Now you can save a document to this server using localhost:5000 as the server path.
