Are my files uploaded to a server?

Never. Every conversion happens entirely inside your browser using WebAssembly and the pdf-lib library. Your Markdown files — and any confidential content in them — never leave your device. There is no signup, no watermark, and no per-file limit.

What Markdown features are supported?

GitHub-Flavored Markdown Support: full support for headings, bold, italics, strikethrough, inline code and fenced code, lists (ordered and unordered), GFM tables, task lists, blockquotes, horizontal rules and links. Code blocks are highlighted in the preview and in exported files. Math equations written in KaTeX language and Mermaid diagrams also render in the preview. Embedded images are also supported when they are base64 data URLs.

How do I add a cover page?

Put YAML front-matter at the top of your .md file with title, subtitle, author, and date, then turn on the "Cover page from front-matter" option. Example: --- title: Q3 Roadmap subtitle: Draft for review author: Alex Chen date: 2026-01-15 ---

Can I combine multiple Markdown files into one PDF?

Yes. In the Batch tab, you can combine all your files into one PDF. Each file becomes a chapter, and a page break appears between chapters. Also, the “Auto table of contents” feature will be enabled to generate a linked table of contents from all your H1 and H2 headings across all files in the set. This is especially powerful for exporting an Obsidian vault, a Notion export, or a docs folder as one big document.

Does it support KaTeX math and Mermaid diagrams?

Yes, in the live preview. Use single dollar signs for inline math ( $E=mc^2$ ) and double dollar signs for block math ( $$…$$ ). For Mermaid diagrams, use a ```mermaid code block. PDF export of the live preview does not necessarily render complex math and Mermaid diagrams well, so they are better exported separately.

Can I convert 100+ files at once?

Yes. In the Batch tab, you can add as many .md files as your browser can hold in memory (for example, 1000+ small files). Each file is converted to a PDF. All files are then packed into a ZIP file unless you disabled this in settings for this conversion.

Why does the PDF look different from GitHub?

GitHub uses web CSS to style the repository’s web pages. ConvertYard’s output, however, uses print-optimized typography for the themes you select (e.g., Modern with Helvetica font, Classic with Times font, or Mono with Courier font). Output such as headings, callouts, tables, and code blocks is styled for print-quality output, not for reading in a web browser tab.

What about GitHub-style callouts like [!NOTE] and [!WARNING]?

Supported. The notes are created with the same syntax as GitHub (e.g., > [!NOTE] This is a note ). The following types are recognized: NOTE, TIP, WARNING, DANGER, CAUTION, and IMPORTANT. Each renders as a colored callout box in both the preview and the PDF.

# Welcome to ConvertYard's Markdown Editor

Everything you write here stays in your browser. No uploads, no accounts, no watermark.

## What works out of the box

- **Full GFM**: tables, task lists, strikethrough
- Syntax-highlighted fenced code
- KaTeX math: $E = mc^2$ and block math:

$$
\int_0^\infty e^{-x^2}\,dx = \frac{\sqrt{\pi}}{2}
$$

- Mermaid diagrams
- Front-matter cover pages (see the top of this file)
- Auto table of contents
- GitHub-style callouts

> [!TIP]
> Drop a folder of .md files in the **Batch** tab to combine them into a single PDF.

Who uses this tool

Developers

Don't build a whole docs website just to send a single spec to a client. Convert your README, changelog, or API docs to a PDF format to send to your colleagues, boss, or client.

Consultants and freelancers

Maintain safety when working under an NDA by converting client notes and reports without sending them through a stranger's server. Your files will always remain on your computer.

Students

Export your class notes from Markdown format to produce a printable study guide. You can even add a cover page with your name, the class, and the date.

Writers

You likely write in Markdown in tools like iA Writer, Ulysses, or even in your own Obsidian notes. That means you can now easily export those to PDF as well, to get a proper print version of your notes without having to bother with copy-pasting them into Google Docs to get the formatting right.

Anyone with a folder of notes

Whether it is your meeting notes, your research, your favorite recipes, or even that first draft of your book, throw the whole folder at it and get a single PDF file back. We can even add a cover page and table of contents for you!

What people use it for

In simple terms, here are the most common ways that people use this tool.

GitHub README to PDF. Export your repository README to PDF to share with people who are not GitHub users.
Export a folder of Obsidian notes as one PDF. Drop the folder. Get one clean file. Read the full guide.
Save ChatGPT / Claude replies with formatting preserved. No more having to take screenshots of code tables and math. See how.
API documentation. Send PDF documentation to a client instead of linking to a docs site.
Convert a Markdown resume to PDF. Choose from a variety of themes and download a PDF ready for application. Learn more.
Convert meeting notes into a handoff document. Add a cover page and a table of contents in one click.
Save a research thread for future reference. Save your work in a PDF that you can open 10 years from now without any special software.
Create a study packet. Combine your notes from a semester into one printable file.

Convert in three steps

It only takes a few seconds.

1
Add your Markdown.
Use the Editor tab above to paste in or write your Markdown. You can see a live preview of your work to the right of the Editor tab. Alternatively, use the Batch tab above to add one or more files (or even a whole folder full of files).
2
Pick your options.
- Choose a theme: Modern (Helvetica), Classic (Times), or Mono (Courier).
- Choose a page size: A4 or Letter.
- You can add a cover page for your title page.
- Enable a table of contents to link together headings throughout your document.
- In Batch mode, enable Combine into one PDF to generate a single document from many files.
3
Download your PDF.
Click the download button to save the generated PDF file directly to your computer. Remember, the Markdown text is never uploaded to the server. Thus, it is never stored on our servers.

All documents — 1 or 500 — are processed the same way: 3 steps to generate your output.

What Markdown features work

Everything you need in a Markdown tool, plus a few sweet extras that the rest of the converters are missing.

The basics

Headings (H1 through H6)
Bold, italic, and strikethrough
Bullet lists and numbered lists
Blockquotes
Links and images
Horizontal rules

GitHub Flavored Markdown

Tables with column alignment
Task lists: - [x] done, - [ ] to do
Fenced code blocks with syntax highlighting
Autolinks (a plain URL becomes a clickable link)

The extras

Cover page from YAML front-matter at the top of the file — we generate the cover for you.
Table of contents. Built from your headings. Can be turned on/off.
GitHub-style callouts: > [!NOTE], > [!TIP], > [!WARNING], > [!DANGER] render as colored boxes.
Math. Inline $E = mc^2$ and block $$E = mc^2$$. Rendered with KaTeX.
Diagrams in the preview. Draw flow charts inside a mermaid code block.
Page breaks. Use  on a line by itself to force a new page in the PDF.
Three themes. Modern (Helvetica), Classic (Times), Mono (Courier).

Until it is actually implemented in the tool (and possibly not at all), every feature not listed here will simply export as plain text without trying to implement part of the feature for you.

Your files stay on your computer

All your files stay on your computer. We run the conversion fully in your web browser using WebAssembly. No files are uploaded. None of your files are stored on any servers. Even after the page has loaded, you can turn off your internet connection and it still works fine.

That is why we can offer things some other tools cannot:

No watermark. Unlike other free markdown to pdf tools (e.g. markdowntopdf.com) which add watermarks to exported PDFs unless you pay for a subscription (£5/24 hours, £19/year etc.) we do not apply watermarks on any conversion.
No signup required, ever.
No file-size or file-count limits. You can convert 1 file or 500 files. Same tool. Same price.
True batch mode. Simply throw one or more files into the folder on the left, then click the “Combine selected files” button on the top right. The resulting PDF will have a cover page and a table of contents. Most converters can only handle one file at a time.

You can easily test out the network claim above as well. Open up the developer tools (F12 in most browsers) for the browser you are testing from. Switch to the “Network” tab and then test out converting a file above. You will see no upload in the console.
