Everything mdprint supports, with examples.
Full CommonMark plus GitHub Flavored Markdown.
mdprint uses markdown-it under the hood - a fast, spec-compliant Markdown parser written in JavaScript. It implements CommonMark exactly, then layers GitHub Flavored Markdown on top. Strikethrough with double tildes, autolinking of bare URLs, fenced code blocks with language tags, and tables with pipe syntax all work the way they do on github.com. If your Markdown renders on a GitHub README, it renders here.
GFM pipe-and-dash syntax with alignment.
Tables use the standard pipe-and-dash syntax. Header row, separator row with --- per column, then data rows. Add a colon at the left, right, or both ends of the separator to control alignment: :-- for left, --: for right, :-: for centered. Long tables that span page breaks repeat their headers on each printed page automatically.
Checkbox syntax with print-friendly rendering.
Write - [ ] for an unchecked task or - [x] for a checked one. They render as actual checkboxes in the preview, and they print as filled or empty squares so the document reads correctly on paper. Task lists work inside nested bullet lists, so you can build hierarchical to-dos.
Reference-style notes that survive page breaks.
Add a footnote marker with [^1] in the text, then define the content elsewhere with [^1]: footnote text. Footnotes are collected at the end of the document with back-references to where they appear. The footnotes section is styled distinctively and uses smaller type, the way you'd expect in a printed paper.
190+ languages via highlight.js with auto-detection.
Fenced code blocks get syntax-highlighted automatically. Specify the language right after the opening backticks (```python, ```typescript, ```rust) for accurate parsing, or omit it and let highlight.js detect the language from the content. Inline code with single backticks gets a subtle monospace background. Code blocks are formatted to avoid page breaks in the middle when printed.
Inline and display equations with print-quality typesetting.
Inline math uses single dollar signs ($E = mc^2$). Block math uses double dollar signs on their own lines. mdprint renders both with KaTeX, which is faster than MathJax and produces print-quality output that survives PDF export at full crispness. All standard LaTeX math commands are supported: fractions, integrals, summations, matrices, Greek letters, and the full AMS-math symbol set.
Flowcharts, sequence, gantt, class, and state diagrams.
Write a fenced code block with the language tag mermaid and mdprint renders it as a crisp SVG diagram. Flowcharts with graph LR or graph TD, sequence diagrams between actors, gantt charts with dates, class diagrams with relationships, state machines - all the diagram types Mermaid supports work. SVG rendering means diagrams stay sharp at any print resolution.
Generated from your heading structure.
Insert ${toc} (or [[toc]]) anywhere in your document to get an automatic table of contents generated from the H2 and H3 headings that follow. The TOC is a list of links in the preview and a nested outline in the printed PDF. Useful for long documents where readers want to jump to a section.
Page breaks, repeating headers, clean typography.
The print stylesheet is purpose-built. Page breaks are avoided in the middle of code blocks, tables, and diagrams. Table headers repeat at the top of each printed page. The page itself uses your settings - A4 or Letter, portrait or landscape, normal/narrow/wide margins. The UI chrome disappears: no toolbar, no editor, just the rendered document.
Light by default. Dark when you want it.
The landing pages stay light because long-form reading is easier on a white background. The editor is the part that's most often used after dark, so it has its own light/dark toggle independent of the page theme. Your preference is remembered locally.
Drag-and-drop or button. .md, .markdown, .txt.
Drop a Markdown file anywhere onto the editor and mdprint loads it. The Import button does the same thing via a file picker. Files are read with the browser's FileReader API - nothing is uploaded. The file's name is used as a suggestion for the PDF filename if your document doesn't start with an H1.
18 languages, RTL support, CJK fonts.
The interface itself is translated into 18 languages: English, Dutch, French, German, Spanish, Portuguese, Simplified Chinese, Traditional Chinese, Russian, Arabic, Vietnamese, Japanese, Korean, Italian, Thai, Indonesian, Turkish, and Hindi. Arabic flips the layout for right-to-left reading. CJK and Indic scripts have appropriate fallback fonts so they render correctly on every device.
A practical guide. Read top-to-bottom, or jump to the section you need.
The fastest way to try mdprint is to start typing in the editor on the home page. It loads with a sample document that exercises every feature - tables, code, math, diagrams - so you can see immediately what a finished page looks like. Delete the sample and type your own content, or paste it from wherever you wrote it.
If you already have a Markdown file on your computer, you have two ways to load it. The first is to drag it from your file manager and drop it on the editor pane. A highlight will appear around the drop zone while you're dragging. Release the file, and the editor fills with its contents. The second is to click the Import button in the toolbar and select the file from the file picker. Both methods read the file locally - nothing is uploaded.
mdprint accepts .md, .markdown, and .txt files. The .txt extension is useful for documents that were written as Markdown but saved with a generic extension by another tool. If you try to import a file with a different extension, mdprint will show an error and leave your current content untouched.
If you've never written Markdown before, the rules are small enough to learn in five minutes. You write plain text, and four characters do most of the work. The # symbol at the start of a line creates a heading - one # for the biggest heading, six ##### for the smallest. The * and _ symbols around a word make it italic with one on each side and bold with two. The - or * symbol at the start of a line creates a bullet point. Indent two spaces to nest one bullet under another.
Code is handled with backticks. One backtick on each side of a phrase formats it as `inline code`. Three backticks on a line by themselves start a code block, and three more end it. If you put a language name right after the opening three backticks (```python, ```typescript, ```sql), the code block gets syntax-highlighted in that language. Without a language hint, the highlighter tries to guess from the content, which usually works for popular languages.
Links and images both use square brackets and parentheses. A link is [the text you see](the URL). An image is the same thing with a leading exclamation mark: . When you print to PDF, image URLs that point to publicly-accessible servers will be fetched and embedded. Images on your local machine or behind authentication will not render - drop them directly into the editor as base64 data URLs if you need them inline.
Tables are the one piece of Markdown that looks fussy in the source but renders cleanly. A header row, a separator row of dashes, and one or more data rows, all separated by pipes. The columns don't have to be aligned in the source - the renderer handles the spacing. Add a colon to one or both ends of the dashes in the separator row to control alignment: :--- for left, ---: for right, :---: for centered.
Math equations use TeX syntax wrapped in dollar signs. A single dollar sign on each side gives you inline math: $a^2 + b^2 = c^2$. Two dollar signs on their own lines give you a display equation, centered on its own line and larger. All the LaTeX math commands you'd expect - \frac, \int, \sum, \sqrt, Greek letters, matrices, the AMS symbol set - work because mdprint uses KaTeX, which implements the same syntax.
Diagrams use Mermaid syntax inside a fenced code block tagged with the mermaid language. The simplest diagram is a flowchart: open with graph LR (left-to-right) or graph TD (top-down), then write nodes connected by arrows. Mermaid also supports sequence diagrams (showing message flow between actors over time), gantt charts (project timelines with dependencies), class diagrams (object relationships), and state diagrams (state machines). The Mermaid documentation has examples for every type.
Footnotes let you keep prose readable while attaching detailed citations or asides. Mark a footnote in your text with [^1] (the number can be anything - they're renumbered in output). Somewhere else in the document, define the footnote with [^1]: the footnote content. mdprint collects all footnotes at the end of the printed document and adds back-references that link each footnote to the place it appears in the text.
If your document is long, drop the literal text [[toc]] into the source where you want a table of contents to appear. mdprint replaces it with a nested list of links to every H2 and H3 in the document. In the printed PDF, the same table of contents becomes a navigation outline that PDF readers can use.
Open the Settings panel from the toolbar to control how your PDF is generated. Page size has two options: A4 (the standard outside North America) or Letter (the standard inside North America). Orientation toggles between portrait and landscape - landscape is useful for documents with wide tables or diagrams. Margins offers three presets: narrow gives you more usable area for dense content, normal is the conventional middle, and wide leaves room for handwritten annotations on a printed copy.
The editor has its own light and dark themes, independent of the rest of the page. The toggle in the toolbar switches between them. The preview and print output stay in light mode regardless, because light backgrounds are what print well on paper.
If you regularly use the same set of options, your last selection is remembered locally and applied automatically the next time you open mdprint on the same browser.
The Print button opens your browser's native print dialog. From there, every modern operating system offers Save as PDF as a destination - Chrome, Firefox, Safari, and Edge all support it on macOS, Windows, and Linux. Going through the print dialog gives you the most control: you can choose any printer, preview each page, change orientation per page if your driver supports it, and on some printers you can change paper trays or stapling.
The Download PDF button skips the print dialog and generates a PDF file directly in the browser, then triggers a download. It uses your current Settings (page size, orientation, margins) to format the output. This route is faster when you know exactly what you want and don't need the print dialog's flexibility. The generated PDF is identical in structure to what the browser would produce via Save as PDF.
Both routes use the same print stylesheet under the hood, so the output is consistent. If a document looks wrong in one, it'll look wrong in the other. The most common difference is rendering of complex diagrams or math: very rarely, browser-to-PDF can rasterize an SVG that the direct download keeps as vector. If you see this, use the Download PDF button - it tends to preserve vectors better.
Page breaks in awkward places. mdprint avoids breaking inside code blocks, tables, and diagrams, but it doesn't second-guess prose. If a heading lands at the bottom of a page with the section content on the next page, the easiest fix is to add a few sentences above or below to push the heading. There's no manual page-break syntax in V1 - adding one is on the V2 list.
Images don't appear in the PDF. The most common cause is an image URL that points to your local file system (file://) or to a server that doesn't allow cross-origin access. Either embed the image as a data URL directly in the Markdown source, or upload it to an image host that allows public read access. Imgur, GitHub's user-content servers, and most CDNs work.
Math doesn't render. Check the source for unescaped dollar signs in regular text - a stray $ can start a math span that swallows the rest of the paragraph. If you need a literal dollar sign in prose, escape it: \$. If the math syntax is correct but the equation still doesn't render, the LaTeX command might not be in KaTeX's supported list - the KaTeX documentation has a complete reference.
The diagram is blank. Mermaid is strict about syntax. The most common errors are a missing space after graph LR, a node ID that contains a space (use camelCase or underscores), or an arrow that points to an undefined node. Open your browser's developer console - Mermaid logs a specific error message when parsing fails.
Tables wrap strangely. If a table is wider than the page, mdprint will scale it down to fit. For very wide tables, switch to landscape orientation in Settings, or restructure the table into a list. PDF doesn't handle horizontal scroll the way the web does.
Use the keyboard shortcuts. Cmd+P (or Ctrl+P on Windows and Linux) opens the print dialog. Cmd+S (Ctrl+S) triggers Download PDF. The browser's own keyboard shortcuts for find (Cmd+F), reload (Cmd+R), and zoom (Cmd+plus/minus) all work normally - they don't conflict with mdprint.
Start every document with an H1. The first H1 becomes the suggested PDF filename, the document title for accessibility, and the prominent heading at the top of the printed page. If you start with H2 or lower, the filename falls back to 'document.pdf' and you'll need to rename it manually after download.
Embed images as data URLs when privacy matters. If you don't want a PDF reader to fetch images from a remote server when it opens your file, convert the image to a base64 data URL and embed it directly. Most operating systems have a built-in or single-purpose tool for this conversion. The resulting file is larger, but it's fully self-contained.
Use task lists for printed checklists. If you're producing a paper checklist - a packing list, a shipping checklist, a step-by-step procedure - use Markdown task list syntax with - [ ]. The boxes print as squares you can tick with a pen.
Combine mermaid and code in technical documentation. A common pattern is to show a flowchart of a process, followed by the actual code that implements it. Markdown lets you do both in the same file, and mdprint renders them in a way that prints cleanly side by side.
Cmd+P or Ctrl+P - open print dialog.
Cmd+S or Ctrl+S - download as PDF.
Cmd+B or Ctrl+B inside the editor - bold the selected text.
Cmd+I or Ctrl+I inside the editor - italicize the selected text.
Cmd+/ or Ctrl+/ inside the editor - toggle comment for the current line (HTML comment in Markdown context).
Esc inside the editor when fullscreen - exit fullscreen.
Markdown is a lightweight plain-text formatting syntax created by John Gruber in 2004. You write what you mean - # for headings, ** for bold, - for bullets - and a renderer turns it into clean HTML, PDF, or printed output. It became the default writing format on GitHub, Reddit, Discord, and most modern developer tools because it removes the cognitive overhead of formatting: you keep typing, and structure emerges.
GitHub Flavored Markdown (GFM) extends the original spec with tables, task lists, fenced code blocks, autolinking, and strikethrough. Most tools today implement GFM, plus a few common extensions: footnotes, math via KaTeX, diagrams via Mermaid, and definition lists. mdprint supports all of them out of the box.
Compared to writing in a word processor, Markdown gives you two advantages that matter for printing. First, the source is a plain text file you own - no proprietary format, no vendor lock-in, no surprise re-flowing when you open it on a different computer. Second, the same source produces consistent output every time: the same headings get the same style, the same code blocks get the same monospace font, the same tables get the same borders. That consistency is exactly what you need when you're printing notes, documentation, papers, or reports.
There are three common approaches. The first is command-line tools like Pandoc - powerful, but they require installation, a working LaTeX setup for serious typography, and a fair amount of trial and error before the output looks right. The second is online converters that ask you to upload your file to a server you don't control. That's fine for a draft, but it's a non-starter for anything confidential, and most of them inject watermarks or paywalls past the first page.
The third approach is what mdprint does: process everything in your browser. You paste or drop a Markdown file into an editor, a JavaScript Markdown parser turns it into HTML, the browser renders it with print-aware CSS, and you either trigger the native print dialog (Save as PDF works on every modern OS) or generate a PDF file directly with a client-side library. No upload, no server round-trip, no waiting.
Three reasons to prefer the in-browser route. First, privacy: a document about a hiring decision, a tax return, or a draft contract should not pass through someone else's server just to become a PDF. Second, speed: once the page is loaded, conversion is instant and you can iterate - tweak a heading, click print, tweak again. Third, offline: once mdprint has loaded once, you can use it on a plane or behind a corporate firewall without anything breaking.
Headings: # H1, ## H2, ### H3 up to ###### H6. Use exactly one H1 per document - that becomes the title in the printed output and the filename suggestion for PDF downloads.
Emphasis: *italic* or _italic_, **bold** or __bold__, ~~strikethrough~~. Combine with **_bold italic_** if you must.
Lists: unordered with -, *, or +; ordered with 1., 2., 3. (numbers don't have to be sequential - Markdown renumbers them). Indent two or four spaces for nesting. Task lists use - [ ] for unchecked and - [x] for checked.
Links and images: [text](https://example.com) for links,  for images. Reference-style links with [text][id] and a separate [id]: https://example.com line keep prose readable.
Code: backticks for inline `code`, triple backticks with an optional language tag for blocks. Specify the language (```python, ```typescript) so the syntax highlighter picks the right grammar.
Tables: pipe and dash syntax. | Column | Column | on one line, |---|---| on the next, then data rows. Alignment markers (:--, --:, :-:) control column alignment in the printed output.
Math: inline with $E = mc^2$, block with $$ \int_0^\infty e^{-x} dx = 1 $$. mdprint uses KaTeX, which renders fast and prints crisply.
Diagrams: a fenced code block with the language tag mermaid becomes a rendered SVG diagram. Flowcharts, sequence diagrams, gantt charts, state machines, class diagrams - all supported.
Every time a document leaves your device, you add risk you cannot fully audit. The receiving server might log the request body. The TLS proxy at the edge might cache it. The third-party analytics script on the upload page might capture the file name. The error monitoring service might pick up a stack trace that includes a snippet. Most of the time none of these things happens - but you can't know which time is the bad time, and you can't undo it after the fact.
Local processing removes the entire class of failure. mdprint downloads the JavaScript it needs once, then runs everything in the browser sandbox: the Markdown parser, the syntax highlighter, the math renderer, the diagram renderer, the PDF generator. Your file never travels. We don't run a server that could see it even if we wanted to.
The privacy guarantee is structural, not promised. There is no upload endpoint to misconfigure, no database where your draft could be retained by accident, no support agent who could be social-engineered into looking at your file. The thing that cannot leak is the thing that was never sent.
Pandoc is the gold standard for document conversion if you're comfortable on the command line and you're producing scientific or book-length output. It's the right tool for an author shipping a 300-page manuscript with custom LaTeX templates. It's overkill for printing a meeting note or a project README.
Typora and Obsidian are excellent Markdown editors with built-in PDF export. They're worth installing if Markdown is your daily writing surface. mdprint is meant for the other case: you have a file you need to print or share once, and you don't want to install anything to do it.
Browser extensions that convert Markdown to PDF generally work by sending the content to a remote service. That re-introduces the privacy issue mdprint exists to avoid. If you need conversion to happen on someone else's machine, you don't need mdprint - you need a hosted service. If you don't, you don't.
Google Docs, Microsoft Word, and Pages can open Markdown but render it inconsistently and don't preserve the source. The PDF output is fine, but every time you open the file you're locked back into the proprietary editor. mdprint keeps your source as plain text. Your file stays portable forever.

mdprint is a free, privacy-first tool for converting Markdown to PDF. It runs entirely in your browser - no upload, no account, no tracking of content.
Most online Markdown-to-PDF converters work by uploading your file to a server. That's a reasonable trade-off for a public README, and a non-starter for a draft contract, a tax document, or any working file. mdprint is the version of those converters that processes everything locally, so the trade-off goes away.
Fokuus is a small web studio based in Belgium. mdprint was built by Anton Pycarelle as a public utility - a tool we wanted ourselves, made available freely. Contact: anton@fokuus.be.
There are no ads, no upsells, no premium tier in V1. Hosting is essentially free (static files on Netlify), so there's nothing to recoup. If we add paid features later they will be additive - the core tool stays free.
V1 covers the full Markdown to PDF flow in 18 languages. The V2 list includes HTML export, DOCX export, a template gallery, and a custom theme editor. Open source is on the V2 list as well.
