Step-by-step instructions and best practices included." --- # HTML to PDF in React Native Nutrient React Native SDK enables you to convert an HTML string or a URL to a PDF document. Generating PDF files from a URL is more powerful — but also more time- and memory-intensive — than generating from an HTML string. For best performance, decide which method to use in the following way: - If the HTML source is short and simple, generate the PDF document from an HTML string. - If the HTML source includes complex structures and a large DOM, generate PDF documents from a URL. If the complex HTML source is stored in a string, first save it to a temporary local file, and then generate the PDF from URL using this file. ## License To convert an HTML string or website to a PDF document, [contact Sales](https://www.nutrient.io/contact-sales) to add PDF Generation to your license. ## Generating PDF documents from an HTML string To generate a PDF document from an HTML string, use the [`Processor`](https://www.nutrient.io/api/react-native/Processor.html) class, which takes a configuration object and an HTML string as its parameters: ```javascript const configuration = { name: fileName, documentPath: `PDFs/${documentName(fileName)}`, override: true, // true|false - If `true`, this will override the existing file with the same name. }; let htmlString = ` Demo HTML Document

Hello HTML

`; try { let { fileURL } = await Processor.generatePDFFromHtmlString(configuration, htmlString); // Do something with the new file. component.props.navigation.push('GeneratePDF', { documentPath: `PDFs/${documentName(fileName)}`, fullPath: mainPath, title: 'Generate PDF from HTML string' }); } catch (e) { console.log(e.message, e.code); alert(e.message); } ``` ## Generating PDF documents from a URL To generate a PDF document from a URL, use the [`Processor`](https://www.nutrient.io/api/react-native/Processor.html) class that takes a configuration object and the URL as its parameters: ```js try { fileURL = await getOutputPath(fileName); } catch (e) { console.log(e.message, e.code); alert(e.message); } const configuration = {filePath: fileURL, override: true}; let originURL = 'https://www.nutrient.io'; try { let { fileURL: outputURL } = await Processor.generatePDFFromHtmlURL(configuration,originURL); } catch (e) { console.log(e.message, e.code); alert(e.message); } ``` See the list with all the [configuration options](https://www.nutrient.io/guides/react-native/pdf-generation/configuration.md) you can use with [`Processor`](https://www.nutrient.io/api/react-native/Processor.html). To test this functionality, see the demo projects in the [Catalog](https://github.com/PSPDFKit/react-native/tree/master/samples/Catalog) app. --- ## Related pages - [Document to PDF in React Native](/guides/react-native/pdf-generation/from-documents.md) - [Generate blank PDFs in React Native](/guides/react-native/pdf-generation/blank-pdf.md) - [Generate PDFs from a template in React Native](/guides/react-native/pdf-generation/from-template.md) - [Image to PDF in React Native](/guides/react-native/pdf-generation/from-images.md) - [PDF generation configuration in React Native](/guides/react-native/pdf-generation/configuration.md) - [Generate PDFs in React Native](/guides/react-native/pdf-generation.md)
