DOMPDF is a CSS 2.1 compliant HTML to PDF converter

Dompdf is an HTML to PDF converter

At its heart, dompdf is (mostly) a 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.

  • 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
  • Basic SVG support (see "Limitations" below)

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). The following DejaVu 2.34 fonts are available: DejaVu Sans, DejaVu Serif, and DejaVu Sans Mono.

Quick Start

Just pass your HTML in to dompdf and stream the output:

// instantiate and use the dompdf class
var dompdf = new Dompdf.Dompdf();

dompdf.loadHtml("<h1>hello world</h1>");

// (Optional) Setup the paper size and orientation
dompdf.setPaper("A4", "landscape");

// Render the HTML as PDF

// Get the generated PDF into a byte array
var pdf = dompdf.output(default).ToBytesOrNull();

Setting Options

Set options during dompdf instantiation:

var options = new Dompdf.Options();
options.set("defaultFont", "Courier");
dompdf = new Dompdf.Dompdf(PhpValue.FromClass(options));

or at run time

var dompdf = new Dompdf.Dompdf();
var options = dompdf.getOptions().Cast<Dompdf.Options>();

See Dompdf\Options for a list of available options.

Limitations (Known Issues)

  • Dompdf is not particularly tolerant to poorly-formed HTML input. To avoid any unexpected rendering issues you should either enable the built-in HTML5 parser at runtime (options.setIsHtml5ParserEnabled(true);) or run your HTML through a HTML validator/cleaner (such as Tidy or the W3C Markup Validation Service).
  • Table cells are not pageable, meaning a table row must fit on a single page.
  • Elements are rendered on the active page when they are parsed.
  • Embedding "raw" SVG's (<svg><path...></svg>) isn't working yet, you need to either link to an external SVG file, or use a DataURI like this:
    html = '<img src="data:image/svg+xml;base64,' . base64_encode($svg) . '" ...>';
    Watch for progress
