IronPdfJava.Examples

Runnable Java examples for IronPDF for Java, a PDF library that converts HTML to PDF with a real Chromium renderer and generates, edits, and extracts PDF content.

Install

<dependency>
    <groupId>com.ironsoftware</groupId>
    <artifactId>ironpdf</artifactId>
    <version>2026.8.2</version>
</dependency>

Quickstart

import com.ironsoftware.ironpdf.License;
import com.ironsoftware.ironpdf.PdfDocument;
import java.io.IOException;
import java.nio.file.Paths;

public class Program {
    public static void main(String[] args) throws IOException {
        License.setLicenseKey("YOUR-LICENSE-KEY");

        PdfDocument pdf = PdfDocument.renderHtmlAsPdf("<h1>Hello, PDF!</h1>");
        pdf.saveAs(Paths.get("hello.pdf"));
    }
}

That produces a working PDF on the first run. To render from other sources, swap renderHtmlAsPdf for renderUrlAsPdf(url) or renderHtmlFileAsPdf(path).

IronPDF for Java downloads and starts IronPdfEngine on the first API call, so the first run takes longer than the ones after it. 设置.setLogPath(Paths.get("IronPdfEngine.log")) puts the engine log somewhere you can read it, and 设置.setDebug(true) makes it verbose.

Without a license key, generated PDFs include a watermark.
