3.1. Using IronPDF

IronPDF provides different methods for creating files. Let's have a look at two of the most important methods.

Existing URL to PDF

IronPDF makes it very simple to generate documents from HTML. The following code sample converts a web page's URL to a PDF.

import com.ironsoftware.ironpdf.*;
import java.nio.file.Paths;

// Set the license key and log path
License.setLicenseKey("YOUR-LICENSE-KEY");
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

// Convert a URL to a PDF
PdfDocument myPdf = PdfDocument.renderUrlAsPdf("https://ironpdf.com");

// Save the PDF document to a file
myPdf.saveAs(Paths.get("url.pdf"));

import com.ironsoftware.ironpdf.*;
import java.nio.file.Paths;

// Set the license key and log path
License.setLicenseKey("YOUR-LICENSE-KEY");
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

// Convert a URL to a PDF
PdfDocument myPdf = PdfDocument.renderUrlAsPdf("https://ironpdf.com");

// Save the PDF document to a file
myPdf.saveAs(Paths.get("url.pdf"));

JAVA

The output is the below URL that is well formatted and saved as follows:

IronPDF URL Output

HTML Input String to PDF

The following sample code shows how an HTML string can be used to render a PDF in Java. You simply use an HTML string or document to convert it to new documents.

import com.ironsoftware.ironpdf.*;
import java.nio.file.Paths;

// Set the license key and log path
License.setLicenseKey("YOUR-LICENSE-KEY");
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

// Convert an HTML string to a PDF
PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1> ~Hello World~ </h1> Made with IronPDF!");

// Save the PDF document to a file
myPdf.saveAs(Paths.get("html_saved.pdf"));

import com.ironsoftware.ironpdf.*;
import java.nio.file.Paths;

// Set the license key and log path
License.setLicenseKey("YOUR-LICENSE-KEY");
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

// Convert an HTML string to a PDF
PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1> ~Hello World~ </h1> Made with IronPDF!");

// Save the PDF document to a file
myPdf.saveAs(Paths.get("html_saved.pdf"));

JAVA

Oto wynik:

IronPDF HTML Output

3.2. Using Apache PDFBox

PDFBox can also generate new PDF documents from different formats, but it cannot convert directly from URL or HTML string.

      // End the content stream

      System.out.println("PDF created");
    }
    // Closing the document
    document.close();
  }
}

PDFBox Pozycjonowane dane wyjściowe

However, if we remove contentStream.newLineAtOffset(25, 700); from the above code example and then run the project, it produces a PDF with output at the bottom of the page. Dla niektórych programistów może to być dość irytujące, ponieważ muszą dostosowywać tekst za pomocą współrzędnych (x, y). y = 0 means that the text will appear at the bottom.
