dompdf is an HTML to PDF converter. At its heart, dompdf is (mostly) CSS 2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer: it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes.

Features

  • handles most CSS 2.1 and a few CSS3 properties, including @import, @media & @page rules
  • supports most presentational HTML 4.0 attributes
  • supports external stylesheets, either local or through http/ftp (via fopen-wrappers)
  • supports complex tables, including row & column spans, separate & collapsed border models, individual cell styling
  • image support (gif, png (8, 24 and 32 bit with alpha channel), bmp & jpeg)
  • no dependencies on external PDF libraries, thanks to the R&OS PDF class
  • inline PHP support

Requirements

  • PHP 5.0+ (5.3+ recommended)
  • DOM extension
  • GD extension

Recommendations

  • MBString extension: provides internationalization support. This extension is not enabled by default. dompdf has limited internationalization support when this extension is not enabled.
  • opcache (OPcache, XCache, APC, etc.): improves performance

About Fonts & Character Encoding

PDF documents internally support the following fonts: Helvetica, Times-Roman, Courier, Zapf-Dingbats, & Symbol. These fonts only support Windows ANSI encoding. In order for a PDF to display characters that are not available in Windows ANSI you must supply an external font. dompdf will embed any referenced font in the PDF so long as it has been pre-loaded or is accessible to dompdf and reference in CSS @font-face rules. See the font overview for more information on how to use fonts.

The DejaVu TrueType fonts have been pre-installed to give dompdf decent Unicode character coverage by default. To use the DejaVu fonts reference the font in your stylesheet, e.g. body { font-family: DejaVu Sans; } (for DejaVu Sans).

Easy Installation

Install with git

From the command line switch to the directory where dompdf will reside and run the following commands:

git clone https://github.com/dompdf/dompdf.git .
git submodule init
git submodule update

Install with composer

To install with Composer, simply add the requirement to your composer.json file:

{
  "require" : {
    "dompdf/dompdf" : "0.6.*"
  }
}

And run Composer to update your dependencies:

$ curl -sS http://getcomposer.org/installer | php
$ php composer.phar update

Before you can use the Composer installation of DOMPDF in your application you must disable dompdf's default auto-loader, include the Composer autoloader, and load the dompdf configuration file:

// somewhere early in your project's loading, require the Composer autoloader
// see: http://getcomposer.org/doc/00-intro.md
require 'vendor/autoload.php';

// disable DOMPDF's internal autoloader if you are using Composer
define('DOMPDF_ENABLE_AUTOLOAD', false);

// include DOMPDF's default configuration
require_once '/path/to/vendor/dompdf/dompdf/dompdf_config.inc.php';

Download and install

Download an archive of dompdf and extract it into the directory where dompdf will reside

Limitations (Known Issues)

  • not particularly tolerant to poorly-formed HTML input. To avoid any unexpected rendering issues you should either enable the built-in HTML5 parser (via the DOMPDF_ENABLE_HTML5PARSER configuration constant) or run your HTML through a HTML validator/cleaner (such as Tidy).
  • large files or large tables can take a while to render
  • CSS float is not supported (but is in the works, enable it through the DOMPDF_ENABLE_CSS_FLOAT configuration constant).
