About

This tool transforms raw LaTeX code into W3C-standard MathML, the native XML markup for displaying mathematics on the web. Unlike image-based solutions, MathML is scalable, accessible to screen readers, and selectable.

The converter uses a custom recursive descent parser to handle complex nesting, including frac (fractions), sqrt (roots), and matrices. It automatically resolves operator precedence for superscripts x² and subscripts x_i, generating clean msubsup tags where necessary.

Formulas

The core parsing logic maps LaTeX structures to the MathML tree.

ParserInput: \frac{a}{b}↓AST: { type: "frac", children: [a, b] }↓Output: <mfrac><mi>a</mi><mi>b</mi></mfrac>

Subscripts and superscripts rely on stack manipulation: PreviousNode + ^ → Wrap(PreviousNode, msup).

Frequently Asked Questions

MathML is semantic text, not pixels. It scales infinitely without blurring, allows users to copy/paste the formula, and is readable by accessibility tools (screen readers) for visually impaired users.

No. This is a standard math-mode parser. It supports standard commands (fractions, roots, sums, integrals, Greek letters, matrices) but does not support text-formatting packages like tikz or bibtex.

Use the standard environment: \begin{matrix} a & b \\ c & d \end{matrix}. Supported variants include pmatrix (parentheses) and bmatrix (brackets).

A red outline indicates a syntax error, usually unbalanced curly braces { } or an unrecognized command. Check your closing brackets.
