How to convert HTML to PDF using Java

The Pdfcrowd API is an online tool that lets you easily create PDF from web pages and raw HTML code in your Java applications. PDFs are created in the cloud, no 3rd party libraries are needed. All you need is a tiny Java API client library.

Code samples

The following code converts a web page to PDF and saves it to a file:

import com.pdfcrowd.*;
import java.io.*;
 
// create an API client instance
Client client = new Client("username", "apikey");

// convert a web page and save the PDF to a file
FileOutputStream fileStream = new FileOutputStream("google_com.pdf");
client.convertURI("http://google.com/", fileStream);
fileStream.close();

Another option is to convert raw HTML code, just use the convertHtml() method instead of convertURI():

FileOutputStream fileStream = new FileOutputStream("MyHtml.pdf");
client.convertHtml("<body>My HTML Layout</body>", fileStream);
fileStream.close();

The API lets you also convert a local HTML file:

fileStream = new FileOutputStream("MyLayout.pdf");
client.convertFile("/path/to/MyLayout.html", fileStream);
fileStream.close();
