# Converting a document from DOCX to PDF/UA format

Converting Word documents (DOCX) to PDF/UA — whether for accessibility compliance, inclusive document creation, or meeting ISO 14289 standards — ensures content is accessible to all users, including those using assistive technologies like screen readers.

## How Nutrient helps you achieve this

Nutrient.NET SDK handles DOCX-to-PDF/UA conversion. With the SDK, you don't need to worry about:

- Parsing Word document structures

- Managing accessibility tagging

- Handling PDF/UA conformance requirements

- Complex rendering logic

Instead, Nutrient provides an API that handles all the complexity behind the scenes, letting you focus on your business logic.

## Complete implementation

Below is a complete working example that demonstrates DOCX-to-PDF/UA conversion.

Import the Nutrient namespace:

```csharp

using Nutrient;

```

Open the Word document — the SDK converts Office formats transparently:

```csharp

try
{
    using Document document = Document.Open("input.docx");

```

Configure PDF/UA conformance and export the document. The `PDF_UA_1` setting ensures the output meets ISO 14289 accessibility standards:

```csharp

    var settings = document.Settings;
    var pdfSettings = settings.PdfSettings;
    pdfSettings.Conformance = PdfConformance.PDF_UA_1;

    document.ExportAsPdf("output.pdf");
    Console.WriteLine("Successfully converted to PDF/UA");
}
catch (NutrientException e)
{
    Console.Error.WriteLine($"Error: {e.Message}");
    Environment.Exit(1);
}

```

## Conclusion

The conversion logic consists of three steps:

1. Open the document.

2. Configure PDF/UA conformance.

3. Export as PDF.

Nutrient handles Word document parsing and accessibility compliance so you don't need to understand document internals or manage PDF tagging manually.

## Error handling

Nutrient.NET SDK handles errors with exception handling. The methods presented in this guide throw a `NutrientException` if a failure occurs. This helps with troubleshooting and implementing error handling logic.
