## Convert HTML to PDF in Xamarin.Android

{% hint style="info" %}
**This tutorial only applies to Xamarin.Android. See Xamarin.iOS equivalent here .**
{% endhint %}

{% hint style="info" %}
**HTML to PDF conversion is available for Android API 19 and above.**
{% endhint %}

{% hint style="info" %}
Internet connection is not required when converting local HTML files. However, it is required for converting HTTP/HTTPS links.
{% endhint %}

The [HTML to PDF](https://sdk.apryse.com/api/xamarinandroid/tools/api/pdftron.PDF.Tools.Utils.HTML2PDF.html) conversion API accepts different sources, such as HTTP/HTTPS URLs, HTML strings, and everything that can be loaded in a [WebView](https://developer.android.com/reference/android/webkit/WebView.html).

## From link

To convert a link URL to PDF, simply:

{% code lineNumbers="true" %}

```csharp
HTML2PDF hTML2PDF = new HTML2PDF(this);
hTML2PDF.FromUrl("http://developer.android.com/about/index.html");
hTML2PDF.ConversionFinished += (sender, e) =>
{
    // do something with e.PdfOutput
};
hTML2PDF.ConversionFailed += (sender, e) =>
{
    // error handling
};
```

{% endcode %}

## From HTML string

To convert an HTML string to PDF, simply:

{% code lineNumbers="true" %}

```csharp
HTML2PDF hTML2PDF = new HTML2PDF(this);
hTML2PDF.FromHTMLDocument(myBaseUrl, myHtmlData);
hTML2PDF.ConversionFinished += (sender, e) =>
{
    // do something with e.PdfOutput
};
hTML2PDF.ConversionFailed += (sender, e) =>
{
    // error handling
};
```

{% endcode %}

where `myBaseUrl` is the URL to use as the page's base URL. If null defaults to `about:blank` and `myHtmlData` is a String of data in the `UTF-8` encoding. Click \[here for more info]\(<https://developer.android.com/reference/android/webkit/WebView.html#loadDataWithBaseURL(java.lang.String>, java.lang.String, java.lang.String, java.lang.String, java.lang.String)).

## From other sources

If none of the above fit your needs, you can also pass in a `WebView` directly for conversion:

{% code lineNumbers="true" %}

```csharp
HTML2PDF hTML2PDF = new HTML2PDF(myWebview);
hTML2PDF.DoHtml2Pdf();
hTML2PDF.ConversionFinished += (sender, e) =>
{
    // do something with e.PdfOutput
};
hTML2PDF.ConversionFailed += (sender, e) =>
{
    // error handling
};
```

{% endcode %}
{% endtab %}

{% tab title="iOS" %}

## Convert HTML to PDF in Xamarin.iOS

{% hint style="info" %}
**This tutorial only applies to Xamarin.iOS. See Xamarin.Android equivalent here .**
{% endhint %}

{% hint style="info" %}
Internet connection is not required when converting local HTML files. However, it is required for converting HTTP/HTTPS links.
{% endhint %}

The platform-specific conversion API also supports HTML to PDF conversion, either with the [`+convertOfficeToPDF:paperSize:completion:`](https://sdk.apryse.com/api/xamarinios/tools/api/pdftronprivate.PTConvert.html#pdftronprivate_PTConvert_ConvertOfficeToPDF_System_String_CoreGraphics_CGSize_System_Action_Foundation_NSString__) method for `.html` files or the [`+convertHTMLStringToPDF:baseURL:paperSize:completion:`](https://sdk.apryse.com/api/xamarinios/tools/api/pdftronprivate.PTConvert.html#pdftronprivate_PTConvert_ConvertHTMLStringToPDF_System_String_Foundation_NSUrl_CoreGraphics_CGSize_System_Action_Foundation_NSString__) for raw HTML text.

The following code shows how to convert an HTML string to PDF:

{% code lineNumbers="true" %}

```csharp
pdftronprivate.PTConvert.ConvertHTMLStringToPDF(htmlString, baseURL, CGSize.Empty, (pathToPDF) => { 
    if (pathToPDF == null) {
        // Failed to convert HTML to PDF.
        return;
    }

    var documentDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

    var urlToPdf = new NSUrl(pathToPDF);
    var destinationURL = (new NSUrl(documentDirectory)).Append(urlToPdf.LastPathComponent, false);
    var destinationFileURL = NSUrl.CreateFileUrl(destinationURL.Path, null);

    NSError error = null;
    var result = NSFileManager.DefaultManager.Copy(urlToPdf, destinationFileURL, out error);
    if (!result) {
        // Failed to copy PDF to persistent location.
    }

    // Do something with PDF output.
});
```

{% endcode %}

where `baseURL` is the URL to use as the page's base URL for resolving relative links in the document.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.apryse.com/xamarin/conversion/html-to-pdf.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
