Markdown to PDF converter

What is Markdown?

Markdown is plain text with a light, readable syntax for headings, lists, links and emphasis that converts cleanly into HTML.

Created by John Gruber in 2004; CommonMark standardised it in 2014.

• Readable as-is, and diffs beautifully in version control
• The native format of GitHub, static site generators and most docs tooling
• Converts to HTML, PDF and DOCX without loss of structure

What is PDF?

PDF is a fixed-layout document format. Fonts, images and positioning are embedded, so the file prints and displays identically on every device.

Created by Adobe in 1993 and an open ISO standard since 2008.

• Pixel-identical layout everywhere, including print
• Universally accepted for contracts, invoices, CVs and forms
• Supports digital signatures, passwords and embedded fonts

Why convert Markdown to PDF?

• PDF is the better fit for final documents that must look the same for everyone, while Markdown is built for documentation, notes and content destined for the web.
• It sidesteps the main drawback of Markdown: limited layout control — no columns, precise positioning or page breaks.
• You gain pixel-identical layout everywhere, including print.
• Recipients see the exact same pagination you do, which matters for anything printed, signed or submitted.
• Compatibility improves where it counts: Every browser, phone and desktop operating system and Acrobat, Preview, Edge, Chrome, Word 2013+ (with reflow).

Quality and file size after conversion

Both formats are lossless, so nothing is thrown away. The output is a byte-faithful representation of the input; only the container and the compression scheme change, which is why sizes differ while the content does not.

Typeset as plain paragraphs on A4 pages.

Compatibility

Markdown opens in GitHub, GitLab, Notion, Obsidian, Bear, Static site generators, documentation platforms and most note apps. PDF opens in Every browser, phone and desktop operating system, Acrobat, Preview, Edge, Chrome, Word 2013+ (with reflow).

If the file has to work for someone else, choose the format their software already understands rather than the one with the best specification.

Limitations to know about

• Structure survives, but the output is no longer editable as plain text.
• Awkward to edit — the format stores placement, not document structure
• Text does not reflow, so reading on a phone often means zooming

When to keep Markdown instead

Markdown is still the right choice for documentation, notes and content destined for the web. Keep the original alongside the converted copy whenever you might need to re-export at a different size or quality — conversion is quick, but recovering discarded detail is impossible.
