# Converting HTML to PDF

HTML content can render differently across browsers, devices, and viewport sizes. Converting HTML to PDF gives you a fixed output format for sharing, archiving, and printing.

Use this workflow to:

- Preserve layout and styling in a stable document format

- Distribute web content for offline access

- Archive rendered pages for audit or compliance workflows

## How Nutrient supports this workflow

Nutrient.NET SDK converts HTML to PDF through a single API call. Nutrient renders the HTML through Chrome, so the PDF preserves the page layout, fonts, images, and styling.

HTML-to-PDF conversion on Linux relies on Chrome for rendering. If you run this workflow in Docker on Linux, make sure the container includes Chrome and runs as a non-root user. For the packaged Docker setup, refer to the [running Chrome-based conversions in Docker](https://www.nutrient.io/guides/dotnet/csharp/deployment/headless-modes-google-chrome.md) guide.

You don’t need to handle:

- HTML parsing and layout

- Rendering fonts, images, and CSS styling

- Page sizing and pagination

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

## Complete implementation

The following example converts a local `input.html` file to PDF. This line sets up the C# application. The using directive brings in the Nutrient SDK namespace:

```csharp

using Nutrient;

```

This line opens the HTML file. The [using declaration](https://learn.microsoft.com/dotnet/csharp/language-reference/statements/using) ensures the document is automatically closed when it goes out of scope, preventing resource leaks:

```csharp

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

```

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

```csharp

    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 has two steps:

1. Open the HTML file.

2. Export it as PDF.

Nutrient renders the HTML through Chrome and writes the result to `output.pdf`, so you don’t need to implement format-specific rendering logic.
