# Convert PDFs and images to PDF/A in MAUI

Nutrient MAUI SDK enables you to convert PDFs, Office documents, and images to PDF/A client-side. For more information on the supported source file formats, see the [list of supported file types](https://www.nutrient.io/guides/maui/about/file-type-support.md).

[Try for Free](https://www.nutrient.io/try)

Nutrient MAUI SDK supports converting source files into all PDF/A versions and conformance levels:

- PDF/A-1a, PDF/A-1b

- PDF/A-2a, PDF/A-2u, PDF/A-2b

- PDF/A-3a, PDF/A-3u, PDF/A-3b

- PDF/A-4, PDF/A-4e, PDF/A-4f

For more information on the long-term preservation of documents, check out our demo video below, or have a look at our [complete guide to PDF/A](https://www.nutrient.io/blog/what-is-pdf-a/).

## Converting documents to PDF/A

To convert a PDF, an Office file, or an image to PDF/A, follow these steps:

1. [Load the source file](https://www.nutrient.io/guides/maui/open-a-document.md).

2. Use the `ExportDocumentAsync` method to convert the source file to PDF/A. This method takes an object as its parameter, which configures the conversion. For conversion to PDF/A, set the `PDFAConformance` property of the configuration object that you pass to the `ExportDocumentAsync` method to one of the values of the `PDFAConformance` enum.

3. Save the output document. The `ExportDocumentAsync` method returns a `Task` that resolves to a `byte[]` that contains the output PDF/A document. You can use the resulting `byte[]` to save or persist the output PDF/A in storage. For more information on downloading or persisting the exported `byte[]`, see the [guides on saving a document](https://www.nutrient.io/guides/maui/save-a-document.md).

The example below loads a PDF document and exports it to a PDF with conformance level PDF/A-4f:

```csharp

var documentFromLocalStorage =
    await PSPDFKitController.LoadDocument(docxFilePath, PSPDFKitController.CreateViewerConfiguration());

var exportConfiguration = documentFromLocalStorage.CreateExportConfiguration();
exportConfiguration.PDFAConformance = PDFAConformance.PDFA_4F;
var exportedDocumentAsPDF =
   await documentFromLocalStorage.ExportDocumentAsync(exportConfiguration);

```

For more control over exporting documents, use [`IExportConfiguration`](https://www.nutrient.io/guides/maui/save-a-document/export-configuration/). If you pass `null` instead, the default configuration will be used:

```csharp

var exportOptions = _document.CreateExportConfiguration();
{
    ExcludeAnnotations = true,
    ExportForPrinting = true,
    ExportIncrementally = false,
    Flatten = true,
};

var exportedDocumentContent = await _document.ExportDocumentAsync(exportConfiguration);

```
