LaTeX to MathML Source Converter
Runs one nonempty LaTeX expression through KaTeX in MathML output mode and returns the source text in a read-only field. It does not render a visual formula or create SVG.
About this latex to mathml source converter
Runs one nonempty LaTeX expression through KaTeX in MathML output mode and returns the source text in a read-only field. It does not render a visual formula or create SVG Applies Unicode-compliant text transformations and parsing directly in the browser tab without data leakage.
Text processing & transformation mechanics
Compiles and renders Markdown content in strict conformance with CommonMark 0.31 and GitHub Flavored Markdown (GFM) specifications. The AST parser transforms Markdown syntax trees (headings, emphasis, tables, task lists, blockquotes, fenced code blocks) into semantic HTML5 or plain text. LaTeX mathematical expressions enclosed in $...$ or $$...$$ are parsed into MathML / KaTeX elements, and table alignment markers (:---, :---:, ---:) are mapped to proper HTML column alignments.
Worked text manipulation example
Scenario: Convert a pasted LaTeX expression into the MathML source returned by KaTeX.
Sample input:
Processing: Run the nonempty expression through KaTeX with `output: "mathml"`; the result is source text in Output.
Illustrative output:
Character encoding & string length boundaries
Empty input and unsupported KaTeX syntax report an error. Display mode is used only for input containing `\begin{` or `\displaystyle`; no TeX document execution, visual rendering, or SVG export is provided.
Text formatting and transformations in LaTeX to MathML Source Converter preserve character integrity. Check edge cases such as multi-line inputs and special characters before downstream use.
In-memory text processing boundary
String operations and Unicode manipulations in LaTeX to MathML Source Converter execute entirely in local browser memory without transmitting input text.
Unicode Consortium & text formatting standards
Unicode Consortium standard annexes (UAX) and character encoding specifications:
- KaTeX options documentation: https://katex.org/docs/options.html (`output: "mathml"`)
- KaTeX MathML serialization used by this implementation; not TeX-document execution

How to use it
- Paste one LaTeX expression.
- Choose Run locally to return the KaTeX MathML source string.
- Read or copy the source text from Output.
Frequently asked questions
What does LaTeX Math Renderer return?+
It removes whitespace at the start and end of one LaTeX expression and calls KaTeX with `output: "mathml"`. The result is a text string returned to the read-only output area, not a visual formula or SVG.
Can you show an input and its result?+
After Run locally, `x^2` returns markup containing `<math` and `<msup>` in the output text. The page shows that returned source as text.
Does it act as a full TeX engine or solve an equation?+
No. It formats one expression through KaTeX; it does not create a downloadable image, execute TeX documents, solve the expression, or judge mathematical correctness.
What happens with empty or unsupported LaTeX?+
An empty expression reports `Enter a LaTeX expression.` KaTeX parse errors are returned instead of silently producing a different formula. Display mode is enabled only when the input contains `\begin{` or `\displaystyle`.
