Math Expression to LaTeX
Convert standard math notation to LaTeX code, or paste LaTeX and preview it rendered — all client-side, no uploads.
Your Data Never Leaves Your Device
Every tool runs entirely in your browser. Nothing you type is uploaded, stored, or logged on our servers.
The Math to LaTeX Converter is a free, client-side tool for developers, students, and technical writers who need to move between standard math notation and LaTeX markup. Type a math expression using familiar syntax — exponents as ^, fractions as a/b, roots as sqrt(x) — and the tool instantly produces the corresponding LaTeX code powered by mathjs.
The LaTeX → Preview tab works in the opposite direction: paste any LaTeX math expression and see it rendered instantly using KaTeX. Toggle between inline and display (block) rendering modes to match how the formula will appear in your document. Both modes run entirely in your browser — no server round-trips, no file uploads, no signup.
FAQ
The converter uses mathjs under the hood and supports standard algebraic notation including arithmetic operators (+, -, *, /), exponents (^), functions like sqrt(), sin(), cos(), tan(), log(), exp(), sum(), integral(), and matrices written as [[a, b], [c, d]]. It follows the same syntax as most scientific calculators.
The converter relies on mathjs's parser which follows strict mathematical syntax. Make sure to use explicit multiplication (*) between terms (e.g. 2*x instead of 2x), and wrap function arguments in parentheses (e.g. sqrt(x+1) not sqrt x+1). Implicit multiplication is not always supported.
Inline mode renders the formula within a line of text at a smaller size — useful for expressions embedded in sentences. Block (Display) mode centers the formula on its own line at full size, which is standard for standalone equations. In LaTeX documents, these correspond to $...$ and \[...\] delimiters respectively.
Yes — the LaTeX → Preview tab lets you paste any LaTeX expression and instantly see it rendered using KaTeX. It supports most common LaTeX math commands including fractions (\frac), square roots (\sqrt), sums (\sum), integrals (\int), Greek letters, and matrices (\begin{pmatrix}...\end{pmatrix}).
No. All conversion and rendering happens entirely in your browser using mathjs and KaTeX. No data is sent to any server.
KaTeX covers the vast majority of math-mode LaTeX but does not support some advanced features like \align environments that require the amsmath package in certain configurations, or custom macros. See the KaTeX support table for a full list of supported functions.
