# Create PDFs from HTML in Flutter
[`Nutrient`](https://pub.dev/documentation/nutrient_flutter/latest/nutrient_flutter/Nutrient-class.html) provides powerful APIs for generating PDF files directly from HTML strings and URIs. It relies on the [WebView](https://developer.android.com/reference/android/webkit/WebView) system for Android and [WebKit](https://webkit.org/) for the iOS implementation. This means there are certain aspects of the conversion process that Nutrient cannot support. This includes, for example, any possible [WebView](https://developer.android.com/reference/android/webkit/WebView) or [WebKit](https://webkit.org/) bugs. The following examples show how to generate a PDF from an HTML string and URI/URL.

## Generating a PDF from an HTML string
The code below shows how to generate a PDF from an HTML string:
```dart
const html = '''
Hello, world!
''';
// Writable output path.
final outputFilePath = ''
// Generate the PDF from the HTML string.
String? generatedPdf = await Nutrient.generatePdfFromHtmlString(html, outputFilePath);
if (generatedPdf == null) {
print('Failed to generate PDF from HTML string.');
return;
}
// Display the generated PDF.
await Nutrient.present(generatedPdf);
```
## Generating a PDF from an HTML URL/URI
The code below shows how to generate a PDF from an HTML URL or URI:
```dart
// Writable output path.
final htmlUrl = Uri.parse('https://pspdfkit.com');
final outputFilePath = ;
// Generate the PDF from the HTML URL.
String? generatedPdf = await Nutrient.generatePdfFromHtmlUri(htmlUri, outputFilePath);
if (generatedPdf == null) {
print('Failed to generate PDF from HTML URI.');
return;
}
// Display the generated PDF.
await Nutrient.present(generatedPdf);
```
