markdown-converter

Convert Markdown into PDF documents on top of phppdf/phppdf.

Markdown is parsed directly into layout primitives (text, lists, tables) — there is no intermediate HTML step.

Installation

composer require phppdf/markdown-converter

Requires PHP 8.4+.

Usage

MarkdownConverter::fromMarkdown() never registers fonts for you — you must register a font under each resource name MarkdownConverterConfig expects (F1–F5 by default) before calling $builder->build().

use PhpPdf\Builder\PdfDocumentBuilder;
use PhpPdf\Markdown\MarkdownConverter;
use PhpPdf\Markdown\MarkdownConverterConfig;
use PhpPdf\Output\PdfMemoryOutput;
use PhpPdf\Serialization\PdfDocumentSerializer;

$markdown = "# Hello World\n\nWelcome to the PDF.";

$config = new MarkdownConverterConfig();

$builder = new PdfDocumentBuilder();
$builder->globalFont($config->getRegularFontName(), 'Helvetica')
    ->globalFont($config->getBoldFontName(), 'Helvetica-Bold')
    ->globalFont($config->getItalicFontName(), 'Helvetica-Oblique')
    ->globalFont($config->getBoldItalicFontName(), 'Helvetica-BoldOblique')
    ->globalFont($config->getCodeFontName(), 'Courier');

MarkdownConverter::fromMarkdown($markdown, $config, $builder);

$output = new PdfMemoryOutput();
(new PdfDocumentSerializer($output))->writeDocument($builder->build());

header('Content-Type: application/pdf');
echo $output->getContent();

ATX and Setext headings, paragraphs, bold, italic, bold italic, inline code, fenced code blocks, ordered/unordered lists (with nesting and GFM task-list checkboxes), blockquotes, thematic breaks, GFM pipe tables (with column alignment), hyperlinks, standalone images, and footnotes.
