Library for easy PDF generation built around wkhtmltopdf and Snappy.


  • Use any type of source: a HTML string, a file, a template or a controller.
  • Add a cover, table of contents, header, footer or contents from any source.
  • Embed resources like fonts, images, stylesheets and scripts.
  • Cache resources to improve performance.

Example usage

    ->setCover(['controller' => CoverController::class])
    ->setTableOfContents(['template' => 'pdf/table_of_contents.xml.twig', 'cache' => 'toc'])
    ->setHeader(['file' => 'header.html'])
    ->setFooter(['template' => 'pdf/footer.html.twig', 'cache' => 'footer'])
    ->setContent(['controller' => ContentController::class])
        'margin-top' => 16,
        'margin-bottom' => 16,
        'header-spacing' => 5,
        'footer-spacing' => 5,

$pdf = $pdfBuilder->getPdf();

Loading content

The PDF builder takes any of the following asset types as a data source.

  • DataAsset: the most basic form: contains only a string holding the text or HTML.
  • FileAsset: loads contents from a given file name.
  • TemplateAsset: loads contents from a Twig template and optional parameters.
  • ControllerAsset: loads contents from a controller action and optional parameters.
  • CachedAsset: caches contents by wrapping any of the above assets.

The asset factory

Use Composer to install the library.

$ composer require endroid/pdf

Now you can create the PDF builder as follows.

$snappy = new Snappy(__DIR__.'/../vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64');
$pdfBuilder = new PdfBuilder(new Pdf($snappy), new AssetFactory());

If you use Symfony Flex the builder is already autowired and ready for injection.

public function __construct(PdfBuilder $pdfBuilder)
    $this->pdfBuilder = $pdfBuilder;

Asset Factory

Each source of content, like the cover, the header / footer or the contents of the PDF can be rendered from different sources. You can specify a controller action, render a template, load a file or use a plain old string as source.

Some assets require external dependencies. For instance, to render a controller action you need a kernel, to render a template you need a templating engine and to create a cached asset you need a cache adapter. The factory lets you create assets of any type without worrying of additional dependencies.

Twig Extension

PDF Generators have a bad reputation in resolving URLs like for fonts, style sheets, scripts or images. This is mainly caused by the fact that PDF generation is executed as a process that has no knowledge of URLs but only looks at internal file paths. Also, header and footer files are often loaded multiple times (once for each page) so we don't want external resources to be fetched every time.

The library comes with a Twig extension that you can use to embed such resources. Whether you have a font, an image or an external stylesheet, you can can use the twig extension to embed it as a base64 encoded string.

<link rel="stylesheet" href="{{ embed('http://hostname/styles.css') }}">

@font-face {
    font-family: 'SCP';
    font-weight: normal;
    src: url('{{ embed('https://fontlibrary.org/scp.ttf') }}');
.cover {
    background-image: url('{{ embed('http://pipsum.com/793x1122.jpg') }}');
    width: 793px;
    height: 1072px;
    padding-top: 50px;
