Markdown to LaTeX

Paste your Markdown and get a compilable LaTeX .tex file back — headings, bold/italic, lists, tables, links, and code blocks all map to real LaTeX commands, inline $...$ and display $$...$$ math pass through untouched, and reserved characters are escaped automatically.

Runs entirely in your browser — files never leave your device.

How it works

  1. 01Paste or upload your Markdown, or click Sample to try a realistic math note.
  2. 02LaTeX source updates automatically as you type. Choose Full document for a standalone file that compiles on its own, or Fragment to paste into an existing .tex file.
  3. 03In Full document mode, optionally set a Title — it fills in \title{} and adds \maketitle.
  4. 04Copy the result or download it as output.tex.
  5. 05Compile with pdflatex, or paste into an Overleaf project.

Frequently asked questions

Is this Markdown to LaTeX converter free?

Yes, with no account or limits. The transformer is a small token walker built for this site, running entirely client-side.

Does my Markdown get uploaded anywhere?

No. Conversion happens entirely in your browser's JavaScript engine — the text never leaves your device, and nothing is sent to a server (unless you use "Open from URL" to fetch a remote file, which is a direct browser request, not a server relay).

Will the downloaded .tex file actually compile?

Yes for standard content — Full document mode wraps it with \documentclass{article} and a minimal preamble (hyperref, graphicx, ulem, listings, plus amsmath whenever math is detected), so pdflatex or Overleaf can compile it as-is. Very unusual Markdown (custom HTML, exotic extensions) may need manual touch-up.

Does it support math formulas?

Yes. Inline math written as $...$ and display math written as $$...$$ pass straight through to the LaTeX output untouched — the underscores, carets, and backslashes inside a formula are never escaped, so \alpha, x^2, and a_i all come out correctly. amsmath is added to the preamble automatically whenever a formula is found. A lone, unpaired $ (like a price, e.g. $5) is treated as ordinary text and escaped to \$ as expected.

What's the difference between Full document and Fragment mode?

Full document wraps the output with \documentclass{article}, the preamble, and \begin{document}/\end{document}, so it compiles standalone with pdflatex or Overleaf — this is the default. Fragment mode returns just the body content with no document wrapper, meant for pasting into a section of an existing .tex file you already maintain.

How are special LaTeX characters handled?

Characters LaTeX treats as syntax — & % $ # _ { } ~ ^ and backslash — are escaped automatically wherever they appear in ordinary text, so they render as literal characters instead of breaking compilation. Characters inside a $...$/$$...$$ math span are the one exception — those pass through unescaped, since they're meant to be read as LaTeX math syntax.

What Markdown formatting is supported?

Headings (H1-H3 as \section/\subsection/\subsubsection, H4-H6 as \paragraph/\subparagraph), bold, italic, strikethrough, inline code, fenced code blocks (as verbatim, or lstlisting when a language hint is present), bullet and numbered lists (including nesting), tables (with column alignment from :---/:--:/---: carried over to the tabular environment), links, images, blockquotes, and inline/display math.

What are the known limitations?

Table columns don't get explicit width control (just l/c/r alignment), strikethrough requires the ulem package (already included in the preamble), and math support covers the $...$/$$...$$ delimiters only — \(...\)/\[...\] aren't recognized as math.
