Code for convert HTML to PDF document

Imports: The necessary classes are imported from the IronPDF for Java library.

import com.ironsoftware.ironpdf.*;

import java.io.IOException;
import java.nio.file.Paths;

import com.ironsoftware.ironpdf.*;

import java.io.IOException;
import java.nio.file.Paths;

License Key: Apply your IronPDF license key. Replace "YOUR-LICENSE-KEY" with your actual license key.

License.setLicenseKey("YOUR-LICENSE-KEY");

License.setLicenseKey("YOUR-LICENSE-KEY");

Set Log Path: Set a log path for the IronPDF engine. This is useful for debugging and monitoring purposes. In this code example, the log path is set to "C:/tmp/IronPdfEngine.log".

Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

Render HTML as PDF: Create a PdfDocument object by rendering the HTML content of a file as a PDF. In this case, the HTML file is named "wordHTML.html". The PdfDocument object, myPdf, holds the converted PDF content.

PdfDocument myPdf = PdfDocument.renderHtmlFileAsPdf("wordHTML.html");

PdfDocument myPdf = PdfDocument.renderHtmlFileAsPdf("wordHTML.html");

Save PDF: Save the PdfDocument object as a PDF document. In this example, the output PDF document is named "wordToPdf.pdf".

myPdf.saveAs(Paths.get("wordToPdf.pdf"));

myPdf.saveAs(Paths.get("wordToPdf.pdf"));

Let's have a look at the complete code example:

import com.ironsoftware.ironpdf.*;

import java.io.IOException;
import java.nio.file.Paths;

// Apply your license key
License.setLicenseKey("YOUR-LICENSE-KEY");

// Set a log path
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

// Render the HTML as a PDF. Stored in myPdf as type PdfDocument;
PdfDocument myPdf = PdfDocument.renderHtmlFileAsPdf("example.html");

// Save the PdfDocument to a file
myPdf.saveAs(Paths.get("html_file_saved.pdf"));

import com.ironsoftware.ironpdf.*;

import java.io.IOException;
import java.nio.file.Paths;

// Apply your license key
License.setLicenseKey("YOUR-LICENSE-KEY");

// Set a log path
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

// Render the HTML as a PDF. Stored in myPdf as type PdfDocument;
PdfDocument myPdf = PdfDocument.renderHtmlFileAsPdf("example.html");

// Save the PdfDocument to a file
myPdf.saveAs(Paths.get("html_file_saved.pdf"));

To summarize, this code snippet shows the process of converting an HTML file to a PDF file using the IronPDF for Java library. It first imports the necessary classes, sets up the license key and log path, and then renders the HTML file as a PDF document. Finally, the converted PDF is saved to a specified file path.
