Converting email files to PDF

Convert email messages (MSG and EML) to PDF when you need long-term records for compliance, legal review, or business documentation. PDF output preserves message content in a stable format.

How Nutrient supports this workflow

Nutrient .NET SDK converts email files to PDF through a single API call.

If you run this workflow inside Docker on Linux, make sure the container includes Chrome and runs as a non-root user. Refer to the running Chrome-based conversions in Docker guide.

You don’t need to manage:

• Email format parsing
• Rendering of headers, message body, and formatting
• Inline images and attachments
• MIME content handling

Use the SDK API to handle conversion logic in your application.

Complete implementation

This example shows a complete email-to-PDF conversion flow. This line sets up the C# application. The using directive brings in the Nutrient SDK namespace:

using Nutrient;

This line opens the email file. The using declaration(opens in a new tab) ensures the document is automatically closed when it goes out of scope, preventing resource leaks:

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

This block exports the file to PDF and saves it as output.pdf. The try-catch block handles potential errors using NutrientException:

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

Summary

The conversion flow has two steps:

1. Open the email file.
2. Export it as PDF.

Nutrient handles email parsing and PDF rendering, so you don’t need to implement format-specific conversion logic.
