Add Markdown first.

Paste Markdown or choose a .md file, review the first page, then make a PDF without uploading the source. Choose US Letter or A4, portrait or landscape, margins, text size and page numbers before converting. The result is reopened, every page is rendered, expected selectable text is compared in order, and safe links are counted before download.

How to turn Markdown into a PDF

  1. Add the Markdown

    Paste Markdown into the source panel or choose a .md file. The text stays in this browser tab.

  2. Set the page

    Choose US Letter or A4, portrait or landscape, margins, text size and page numbers.

  3. Check the preview

    The first PDF page appears before conversion so you can review the layout.

  4. Convert and verify

    The output is reopened. Every page is rendered, expected selectable text is compared in order and safe links are counted before download.

What this version draws

The writer covers CommonMark text structures plus tables. It does not run plugins, execute HTML, fetch remote media or turn diagrams into pictures. The visible page uses standard PDF fonts, so unsupported characters stop the job with a specific error. A markdown to pdf converter that silently drops a character is worse than one that stops.

The preview is a real conversion, not a mock-up. Changing the paper, orientation, margin, text size or page numbering rebuilds it from the same source text, and the line under it reports how many pages the document takes at those settings. A layout problem you would otherwise meet after downloading shows up while a different setting still costs one click.

The receipt separates writing from proof. A valid PDF structure is not enough: every page must reopen and render, expected text must remain selectable in order and every safe link annotation must still be present.

Page settings and file name

Narrow, Standard and Wide margins are 36, 54 and 72 points, or half an inch, three quarters of an inch and one inch. Small, Standard and Large text set the body to 10, 12 or 14 points. Code and table text print at 82% of that size. When page numbers are on, they are centered at the foot of each page in 9-point type.

The PDF keeps the name of your .md file and swaps the extension for .pdf. Characters other than unaccented letters, digits, dots, hyphens and underscores become hyphens. Pasted text with no chosen file downloads as document.pdf.

Questions

Does the Markdown leave my browser?
No. The source, generated PDF and page preview stay in this browser tab.
Which Markdown is supported?
Headings, paragraphs, bold, italic, safe links, ordered and unordered lists, blockquotes, fenced code, thematic breaks and tables are supported.
What is refused?
Raw HTML, scripts, CSS, embedded or remote images, Mermaid diagrams and unsafe link schemes are refused. This version also refuses characters the bundled PDF fonts cannot draw instead of dropping them.
Can a link load content during conversion?
No. The tool never follows a link. It writes safe http, https and mailto addresses as PDF link annotations, then checks that the annotations survived.
How is the PDF checked?
The tool opens the new PDF with an independent reader, renders every page, checks page count and compares the expected selectable text in order. At least 98% must remain.
Why can some Unicode text be refused?
This first release uses the standard fonts bundled with PDF readers. Text outside those fonts is refused with an error rather than replaced with empty boxes.
How large can the Markdown be?
The source can be up to 2 MB. A larger file is refused before its text is read. A document that parses into more than 30,000 Markdown tokens is refused, and the finished PDF may not pass 500 pages. Split a longer document into smaller files.
Which fonts does the PDF use?
Body text is set in Helvetica, with bold, italic and bold italic styles. Code is set in Courier. Western European accented letters such as é, ñ and ü, curly quotes, en and em dashes, the euro sign and the trademark sign are drawn. Other scripts, such as Greek, Cyrillic or Chinese, stop the job.
