This short tutorial guides on how to convert URL to PDF in Java. It has all the details to set the IDE, a list of steps describing the process to transform URL to PDF in Java and a sample code for developing a basic converter. Various options are available for customization of the output PDF that you can perform according to your requirements.
Steps to Change Link to PDF Document in Java
- Set the IDE to use Aspose.PDF for Java to change the URL to PDF
- Define the webpage URL for conversion to PDF
- Configure the output PDF page settings and other parameters with the HtmlLoadOptions class
- Fetch the webpage content
- Generate a PDF file from the webpage contents by loading the contents into the Document object
- Save the resultant PDF document
These steps summarize how to turn URL into PDF in Java. Define the webpage URL, configure the output PDF page settings, and fetch the webpage contents. Create a PDF Document object from the webpage contents and save the output PDF using the desired page settings.
Code to Convert Website Page to PDF in Java
| import com.aspose.pdf.*; | |
| import java.io.*; | |
| import java.net.*; | |
| public class HtmlToPdfConverter { | |
| public static void main(String[] args) throws Exception { | |
| // Initialize and apply Aspose.PDF license | |
| License pdfLicense = new License(); | |
| pdfLicense.setLicense("license.lic"); | |
| // Convert an online HTML page to PDF | |
| generatePdfFromWebPage(); | |
| System.out.println("Webpage Link to PDF process finished."); | |
| } | |
| // Method to fetch and convert an HTML webpage to a PDF document | |
| private static void generatePdfFromWebPage() { | |
| // Define the webpage URL to be converted | |
| final String webpageUrl = "https://docs.aspose.com/"; | |
| // Configure PDF page settings for conversion | |
| HtmlLoadOptions pdfOptions = new HtmlLoadOptions(webpageUrl); | |
| pdfOptions.getPageInfo().setWidth(1200); // Setting custom page width | |
| pdfOptions.getPageInfo().setHeight(850); // Setting custom page height | |
| pdfOptions.getPageInfo().setLandscape(false); // Keeping portrait orientation | |
| // Fetch the webpage content and create a PDF document | |
| try (InputStream webContentStream = fetchWebContentAsStream(webpageUrl); | |
| Document pdfDocument = new Document(webContentStream, pdfOptions)) { | |
| // Save the generated PDF file | |
| pdfDocument.save("Converted_WebPage.pdf"); | |
| } catch (IOException e) { | |
| e.printStackTrace(); | |
| } | |
| } | |
| // Method to retrieve the content of a webpage as a stream | |
| private static InputStream fetchWebContentAsStream(String webpageUrl) throws IOException { | |
| // Create a URL object from the given webpage URL | |
| URL url = new URL(webpageUrl); | |
| // Open a connection to the URL | |
| HttpURLConnection connection = (HttpURLConnection) url.openConnection(); | |
| // Set the request method to GET | |
| connection.setRequestMethod("GET"); | |
| // Allow input stream retrieval | |
| connection.setDoInput(true); | |
| // Establish the connection | |
| connection.connect(); | |
| // Return the webpage content as an input stream | |
| return connection.getInputStream(); | |
| } | |
| } |
This code has demonstrated the development of a URL link to PDF converter in Java. You can set page margin, default text state, flag to render the whole content to a single page, and set page layout. If you have already downloaded the webpage contents, you may convert it to PDF by creating a document object and saving it on the disk.
