Markdown to PDF
Professional PDFs from Markdown.
HTML to PDF is a pain. You run a headless browser and keep print styles working after every update. legivel takes your Markdown and sends back a typeset PDF, from one API call, the editor or your AI agent. Nothing to install, 100 free documents a month.HTML to PDF is a pain to keep running. legivel typesets your Markdown instead, from one API call. 100 free documents a month.
Free for 100 documents a month, no card. Paid plans from $19 a month. No document storage.
Typeset, not printed
The same Markdown, two PDFs.
A common Markdown converter turned this file into a web page, and a browser printed it. legivel set the same file as a document. Below, page 1 of one file, both ways.
- The formula stays as source text.
- The diagram stays as code.
- The formula is set as math.
- The diagram is drawn as vector art.
- The command wraps inside the page.
What usually breaks
What goes wrong in a PDF, and what legivel does about it.

- Math
- Often goes wrong: Left as source text in a file printed as it is
- With legivel: Set as math, in vector glyphs
- Diagrams
- Often goes wrong: Mermaid left as a code block
- With legivel: Drawn as vector art where you wrote them
- Fonts
- Often goes wrong: Different fonts on every machine

Invoices and packing slips from your data, one call each.
An order has five line items or fifty. The template you fill today cannot take a varying number of line items.
Start from an invoice, a letter, a shipping label or a certificate, and put fields where the data goes. The editor shows the page the way the PDF prints it.
Then each document is one API call, or one tool call from your agent. JSON fills the fields, and a list or CSV fills the table, one row per item.
Templates you save, with their sample records, are stored encrypted until you delete them.

Developers

An agent writes Markdown well. legivel turns its answer, with tables, charts and diagrams, into a PDF a person can use.
Features

Questions
Something else? support@legivel.com
Do I need an account?
Not to try it. The playground on this page and the Convert page make a watermarked PDF without an account. A free account gives you 100 documents a month without a watermark, no card.
What Markdown does legivel support?
CommonMark plus the GitHub extensions: tables, task lists, footnotes, definition lists, alerts and strikethrough. Beyond that, a [TOC] marker that renders with real page numbers, front matter that becomes the PDF's document information, code colored in 23 languages and color emoji.
Do Mermaid diagrams and LaTeX math really render?
Yes, as vector drawings, not as screenshots. Thirty-three kinds of Mermaid diagram and chart are drawn directly, where they are written in the text; on request, each diagram gets a page of its own, sized to fit and linked from the text. LaTeX math is drawn the same way, inline and on its own line.
Why does this look different from other converters?
A common converter turns your Markdown into a web page, and a browser prints that page. The printout has no contents page with page numbers. A diagram can be split across two pages. legivel typesets the document instead. You get a contents page with page numbers. On request, each diagram gets a page of its own.
Can I automate it, or use it from an AI agent?
Yes. Send your Markdown in one request and the finished PDF comes back, so it fits any script or build step. AI agents use legivel the same way through its MCP server. The editor on this page is that same converter with a preview in front of it.
What happens with my images?
Your images work out of the box. Images embedded in the document always render. Images linked from the web are loaded too, for signed in accounts, over a secure connection, each time you convert. We keep none of them: the images, your document and the finished PDF leave our server the moment the PDF is delivered. Images inside a template you save are stored with it, encrypted. How we load images.
What does it cost?
Free gives you 100 documents a month with no card and no watermark. Paid plans start at $19 a month for 1,000 documents. See plans.
