Convert Markdown to PDF in three steps
- Add Markdown. Paste it into the editor, open a
.mdfile, drop a file onto the file area, or load a template. - Review the paginated preview. Choose the page, typography, theme, and optional document controls, then check each page in the live preview.
- Save the PDF. Choose Download PDF, select Save as PDF in the browser dialog, confirm the suggested filename and paper settings, and save.
Supported Markdown and document syntax
| Feature | Syntax | PDF behaviour |
|---|---|---|
| GFM basics | Headings, links, images, tables, fenced code, task lists, autolinks, strikethrough | Styled, selectable text; links remain clickable where the browser supports them |
| Syntax highlighting | ```js, ```python, and other supported language tags | Highlighted code avoids page breaks when it fits on one page |
| Math | $E=mc^2$ or $$…$$ | Rendered with KaTeX; the accessible MathML is retained |
| Mermaid | ```mermaid fenced diagram | Rendered to vector SVG |
| Footnotes | Claim[^1] and [^1]: Source note | Linked note list at the end |
| GitHub alerts | > [!NOTE], TIP, IMPORTANT, WARNING, CAUTION | Labelled callout block |
| Table of contents | [[toc]] or the automatic TOC option | Linked heading list |
| Page break | <!-- pagebreak -->, \pagebreak, or ::: pagebreak on its own line | Starts a new page in preview and PDF |
Realistic input and output
This example exercises tables, a task list, code, math, a Mermaid diagram, a link, and an image. Load the technical report or academic template to try these features in the live preview.

PDF output
The PDF contains a checked and unchecked task, a bordered results table, highlighted code, typeset math, a vector flowchart, a clickable link, and the referenced image if its host allows the browser to load it. Text stays selectable because export does not use a screenshot canvas.
Download PDF versus Print to PDF
| Action | Best for | What happens |
|---|---|---|
| Download PDF | A clean save workflow and chosen filename | Opens an isolated copy of the paginated document, sets your output name as the suggested title, then opens the browser print dialog. |
| Print to PDF | Printing or saving directly from the current tab | Prints the same generated page DOM from this tab. Select your printer or Save as PDF. |
Both routes use the browser print engine. In the dialog, keep the page size and orientation aligned with the preview, use 100% scale, disable browser-added headers and footers, and select Save as PDF when you want a file.
Common uses
Technical documentation
Export README files, API notes, specifications, architecture diagrams, release notes, and client hand-offs with code and live links.
Academic and research notes
Combine headings, citations in footnotes, tables, equations, diagrams, page numbers, and an automatic table of contents.
Business documents
Turn meeting notes, reports, project plans, and Markdown resumes into consistently paged documents without creating an account.
Limitations and troubleshooting
- Missing images: use a data URL or public HTTPS URL. External images contact their host; authentication, Content Security Policy, hotlink protection, or an offline connection can prevent loading. The preview marks failures before export.
- CORS: browser-native PDF output does not need canvas access, but a host can still deny or replace the image request. If reliability matters, embed a small image as a data URL.
- Page breaks: use the explicit page-break syntax between sections. Tables, code, diagrams, images, and callouts avoid splitting when they fit on a page; an element taller than a whole printable page must split or overflow.
- Wide tables or code: choose landscape, reduce the base font, or shorten unbroken content. The converter wraps code, but dense tables can become cramped.
- Fonts: built-in font stacks work without uploads. Exact font embedding and glyph coverage depend on the browser, operating system, and font licence.
- Very long files: files are limited to 2 MiB and editor content to 250,000 characters. Pagination is debounced and may take several seconds near that ceiling; the export button waits for the latest render.
- Unavailable libraries: Markdown parsing, pagination, highlighting, KaTeX, and Mermaid come from jsDelivr. The status area identifies a failed dependency; ordinary Markdown falls back to a simpler page preview if pagination is unavailable.
- Browser support: use a current Chrome, Edge, Firefox, or Safari with JavaScript and printing enabled. Save-dialog controls, link preservation, outlines, and font embedding vary by browser and operating system.
Privacy details: Markdown text is not uploaded and is not stored by Starlight Tools. Optional recovery uses this browser's local storage. The page downloads its converter libraries from jsDelivr, and any external image in your Markdown is requested directly from that image host.
Markdown to PDF FAQ
Is this Markdown to PDF converter free?
Yes. The converter is free to use, requires no account, and adds no watermark.
Is my Markdown uploaded or stored on a server?
No. Markdown parsing and pagination happen in your browser. The optional recovery draft is stored only in your browser's local storage; Starlight Tools does not receive or store the document.
Does it support GitHub Flavored Markdown and README files?
Yes. It supports common GitHub Flavored Markdown used in README files, including tables, fenced code, task lists, autolinks, and strikethrough, plus GitHub-style alerts.
Are tables and code highlighting included in the PDF?
Yes. Tables and syntax-highlighted code use the same styled document in the preview and PDF. Very wide tables may still need landscape orientation or a smaller font.
Does it support math and Mermaid diagrams?
Yes. KaTeX renders inline and display math, and Mermaid fences render as vector SVG diagrams when those libraries can be downloaded. An unavailable dependency is reported in the status area.
What image sources work?
Data URLs and browser-readable HTTPS image URLs work best. An external image URL makes a request to that image host, and the host may block loading through access rules, authentication, hotlink protection, or browser security policy.
Do links remain clickable?
Yes in browsers whose Save as PDF feature preserves links, including current Chromium-based browsers. Links remain real HTML links rather than pixels in a screenshot.
How do I force a page break?
Put <!-- pagebreak -->, \pagebreak, or ::: pagebreak on its own line. The preview and exported document start a new page at that point.
Does the converter work on mobile?
Yes. Narrow screens use separate Editor and Preview tabs, fit the preview to the viewport, and keep Download PDF within thumb reach. The final save dialog depends on the mobile browser and operating system.
Which browsers are supported?
Use a current version of Chrome, Edge, Firefox, or Safari with JavaScript and printing enabled. Save as PDF controls and preservation of links or document outlines vary by browser and operating system.
Is the PDF text searchable and selectable?
Yes. Export uses the browser's native print engine instead of flattening pages into screenshots, so text remains searchable and selectable and Mermaid SVGs remain vector graphics. Exact font embedding depends on the browser and font license.
What is the difference between Download PDF and Print to PDF?
Download PDF opens an isolated copy of the paginated document and suggests your chosen filename before the browser dialog appears. Print to PDF prints the same paginated preview from the current tab. Both use the browser's native print engine for accessible text and links.
