Convert HTML to PDF in CodeIgniter using Dompdf

Nowadays PDF is the most used format in various web applications. There are multiple libraries like TCPDF, Snappy, mPDF etc can be used to create PDF in a web application. DomPDF is one of the most popular libraries to convert your data into PDF. Here are very easy steps to create HTML to PDF:

We are using default views/welcome_message.php with controller/welcome.php to generate pdf that is easy to understand. You can add your model & include it into the controller.

Step 1: Download DOMPDF from here. Paste it into application\libraries folder
Step 2: Create a file name named Pdf.php into application\libraries folder and paste below code.

if (!defined('BASEPATH'))
  exit('No direct script access allowed'); 
require_once 'dompdf/';
use DompdfDompdf;

class Pdf extends Dompdf { 
    public function __construct() { 

Step 3 : Now create an controller that renders html view to PDF.


if (!defined('BASEPATH'))
        exit('No direct script access allowed');
class Welcome extends CI_Controller {
	function GeneratePdf(){
		$html = $this->output->get_output();
        		// Load pdf library
		$this->pdf->setPaper('A4', 'landscape');
		// Output the generated PDF (1 = download and 0 = preview)
		$this->pdf->stream("html_contents.pdf", array("Attachment"=> 0));		

Step 4 :In above controller we have used default welcome.php, you can replace with YOUR_VIEW.php file. Create a model if you are using custom view in step4 and load it into controller.

defined('BASEPATH') OR exit('No direct script access allowed');
