WYSIWYPDF -- What You See Is What You PDF

The dockerless PDF generator for Symfony. Just Chrome. No containers, no wrapping, no kidding.

composer require daif/chrome-pdf-bundle

Why this bundle?

I wanted to use sensiolabs/gotenberg-bundle -- it's a great and complete Symfony bundle for PDF generation. But it relies on Gotenberg, which requires a running Docker container.

In my case, working in on-premise environments (banking, insurance, regulated industries), Docker is simply not available on production servers. Security policies and infrastructure constraints prevent running containers.

Yet these same machines almost always have a browser installed, or can easily add one. Google Chrome and Chromium are well-maintained, widely trusted, and available on virtually every Linux distribution through standard package managers.

So I built ChromePdfBundle: the same clean builder-based API, but driving Chrome/Chromium directly via the Chrome DevTools Protocol -- no Docker, no external service, no extra infrastructure.

Docker-based solutions	ChromePdfBundle
Require Docker + a running container	Requires only a Chrome/Chromium binary
HTTP calls to an external service	Direct communication via CDP
Extra infrastructure to maintain	Uses a browser already on the system
Not usable in Docker-free environments	Works everywhere Chrome runs

How to install

Requirements

PHP 8.1+
Symfony 6.4 / 7.x / 8.x
Google Chrome or Chromium installed on the system (see Chrome installation guide)

composer require daif/chrome-pdf-bundle

This installs the bundle along with chrome-php/chrome, the PHP library used to communicate with Chrome via the DevTools Protocol.

Enable the bundle

If not using Symfony Flex, manually register the bundle:

// config/bundles.php

return [
    // ...
    Daif\ChromePdfBundle\DaifChromePdfBundle::class => ['all' => true],
];

Configuration

Create a minimal configuration:

# config/packages/daif_chrome_pdf.yaml

daif_chrome_pdf:
    assets_directory: '%kernel.project_dir%/assets'

The bundle will automatically detect Chrome/Chromium on your system. You can also specify the binary path explicitly:

daif_chrome_pdf:
    chrome_binary: '/usr/bin/google-chrome'

Basic Usage

PDF from Twig template

namespace App\Controller;

use Daif\ChromePdfBundle\ChromePdfInterface;
use Symfony\Component\HttpFoundation\Response;

class InvoiceController
{
    public function generateInvoice(ChromePdfInterface $chromePdf): Response
    {
        return $chromePdf->html()
            ->content('invoice.html.twig', [
                'invoice' => $invoice,
            ])
            ->generate()
            ->stream()
        ;
    }
}

PDF from URL

use Daif\ChromePdfBundle\ChromePdfInterface;

class ReportController
{
    public function generateReport(ChromePdfInterface $chromePdf): Response
    {
        return $chromePdf->url()
            ->url('https://example.com/report')
            ->generate()
            ->stream()
        ;
    }
}

PDF from Markdown

use Daif\ChromePdfBundle\ChromePdfInterface;

class DocController
{
    public function generateDoc(ChromePdfInterface $chromePdf): Response
    {
        return $chromePdf->markdown()
            ->wrapper('wrapper.html.twig')
            ->files('content.md')
            ->generate()
            ->stream()
        ;
    }
}

Screenshot

use Daif\ChromePdfBundle\ChromeScreenshotInterface;

class ScreenshotController
{
    public function capture(ChromeScreenshotInterface $chromeScreenshot): Response
    {
        return $chromeScreenshot->html()
            ->content('page.html.twig')
            ->generate()
            ->stream()
        ;
    }
}

Twig assets

If a template needs to link to a static asset (image, CSS, font), use the {{ chrome_pdf_asset() }} Twig function:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8"/>
    <title>My PDF</title>
</head>
<body>
    <img src="{{ chrome_pdf_asset('img/logo.png') }}" alt="Logo"/>
</body>
</html>
