Convert Markdown to PDF in Python

To convert Markdown to PDF in Python, call Converter.convert_markdown() to create an intermediate HTMLDocument, then pass that document, PdfSaveOptions, and the output path to Converter.convert_html().

Markdown is a lightweight text format without a fixed page model. PDF uses defined page dimensions, margins, fonts, and pagination. Aspose.HTML for Python via .NET first converts Markdown to an HTML document and then renders that document to PDF.

Convert Markdown to PDF in Python

Follow these steps for a basic Markdown-to-PDF conversion:

1. Convert the source Markdown file to an HTMLDocument with Converter.convert_markdown().
2. Create PdfSaveOptions with the default PDF settings.
3. Pass the document, options, and output path to Converter.convert_html().

import aspose.html.converters as conv
import aspose.html.saving as sav

with conv.Converter.convert_markdown("input.md") as document:
    options = sav.PdfSaveOptions()
    conv.Converter.convert_html(document, options, "output.pdf")

The context manager closes the intermediate HTMLDocument after conversion. Relative images and other resources in the Markdown source are resolved from the source document location, so keep referenced files at valid relative paths.

Convert Markdown to PDF with A4 Page Settings and Metadata

Use PdfSaveOptions when the PDF requires a specific page size, margins, metadata, background, image-compression setting, or encryption. The following example converts an existing Markdown file to an A4 PDF with 2 cm margins and adds document metadata:

1. Convert the Markdown source to an intermediate HTMLDocument.
2. Create PdfSaveOptions.
3. Configure the required page size and margins through page_setup.
4. Set the PDF title, author, subject, and keywords through document_info.
5. Convert the HTML document to PDF with Converter.convert_html().

import os
import aspose.html.converters as conv
import aspose.html.drawing as dr
import aspose.html.saving as sav

input_dir = "data"
output_dir = "output"
os.makedirs(output_dir, exist_ok=True)

input_path = os.path.join(input_dir, "document.md")
output_path = os.path.join(output_dir, "markdown-a4.pdf")

options = sav.PdfSaveOptions()
options.page_setup.any_page.size = dr.Size(
    dr.Length.from_centimeters(21.0),
    dr.Length.from_centimeters(29.7)
)
options.page_setup.any_page.margin = dr.Margin(
    dr.Length.from_centimeters(2.0),
    dr.Length.from_centimeters(2.0),
    dr.Length.from_centimeters(2.0),
    dr.Length.from_centimeters(2.0)
)

document_info = options.document_info
document_info.title = "Markdown Report"
document_info.author = "Documentation Team"
document_info.subject = "Markdown to PDF Conversion"
document_info.keywords = "Markdown, PDF, Aspose.HTML"

with conv.Converter.convert_markdown(input_path) as document:
    conv.Converter.convert_html(document, options, output_path)

The example defines the physical page layout explicitly and stores descriptive metadata in the generated PDF. Change or omit the metadata values according to the document workflow; they do not alter the visible page content.

PdfSaveOptions for Markdown to PDF

Configure only the settings required by the output:

Property	Use it to control
page_setup	PDF page dimensions, margins, and page layout.
background_color	Color behind the rendered document content.
jpeg_quality	JPEG compression quality when JPEG compression is used. It does not increase source-image resolution.
document_info	PDF metadata such as title, author, subject, and keywords.
encryption	PDF passwords, permissions, and encryption settings.
is_tagged_pdf	Whether tagged PDF structure is created. This option alone does not guarantee an accessible or standards-compliant PDF.

Markdown Resources, CSS, and PDF Layout

Images referenced with relative Markdown paths are resolved from the location of the source .md file. Keep those files available during conversion and verify filename case on case-sensitive systems. Remote images must be reachable from the conversion environment.

Markdown is converted to HTML before PDF rendering. Consequently, available fonts, generated HTML structure, CSS rules, page dimensions, and margins affect line wrapping and page breaks. The resulting PDF can differ from a Markdown editor preview because editors may use different stylesheets, fonts, viewport widths, and Markdown extensions.

Common Markdown to PDF Issues

Issue	Likely cause and solution
Images are missing	A relative path is invalid, the resource is unavailable, or filename case does not match. Check resource paths relative to the Markdown file.
Text uses a different font	A required font is not available in the conversion environment. Install or provide the font used by the document styles.
Page breaks differ from the Markdown preview	PDF uses fixed pages, while the preview may use a responsive browser layout. Review page size, margins, fonts, and CSS break rules.
Wide tables or code blocks are clipped	The content exceeds the available page width. Increase the page width, reduce margins, or adjust the generated HTML and CSS.
The PDF file is unexpectedly large	High-resolution images and image compression settings can increase the file size. Optimize source images and adjust jpeg_quality when JPEG compression is used.

FAQ

Can I convert an MD file to PDF in Python?

Yes. .md is the common extension for Markdown files. Pass the MD path to Converter.convert_markdown(), then convert the returned HTMLDocument with PdfSaveOptions and Converter.convert_html().

Why does the PDF look different from my Markdown preview?

Markdown previews use editor-specific HTML, CSS, fonts, and viewport sizes. Aspose.HTML creates its own intermediate HTML document and renders it on fixed PDF pages, so line wrapping, spacing, colors, and page breaks can differ.

Can I convert Markdown to PDF for free?

You can evaluate Aspose.HTML for Python via .NET without a license, but evaluation output has limitations such as a watermark and processing limits. Request a free temporary license for unrestricted testing, or use the online Markdown to PDF Converter below for an occasional manual conversion. See Licensing for license setup.
