Chrome extension for web equations

Copy web equations in the format you need

Nitrax Math Bridge detects equations rendered with KaTeX, MathJax, or MathML, then lets you copy or export them for your document, editor, or publishing workflow.

Works from rendered equations already visible on the page.

From rendered equation to practical format

A formula can look correct on a web page while being awkward to reuse in another application. Nitrax Math Bridge keeps the equation visible, then gives you a format that fits the next step.

Detect the equation

The extension recognizes equations displayed through KaTeX, MathJax, and native MathML markup.

Choose the output

Copy structured notation for an editor or export a rendered file when an image or document asset is the better fit.

Keep the source page open

The tool works beside the equation in Chrome, so you can continue reading while you move the result to the next app.

How it works

Open a page that contains a supported rendered equation. Point to the equation, then use the action bar to copy it in a selected format or export a file.

DetectChoose formatCopy or export

Supported copy and export formats

Use source formats when you want to continue editing notation elsewhere, or rendered formats when you need the equation as a visual asset.

Source and markup

LaTeX, Typst and MathML

Copy an equation into workflows that use TeX notation, Typst markup, or MathML structure.

Text-friendly formats

UnicodeMath and Markdown

Use UnicodeMath for compatible math-input workflows, or Markdown when your document keeps formulas in Markdown notation.

Rendered files

PNG, SVG, JPG and PDF

Export the rendered equation as a raster image, a scalable SVG, a JPG, or a PDF file.

Three steps on a supported page

Install Nitrax Math Bridge

Install the extension from the Chrome Web Store. Pin it if you want quick access to its settings.

Open a page with an equation

Look for equations rendered through KaTeX, MathJax, or MathML on the page you are reading.

Copy or export the result

Choose the format that suits the destination, from editable source notation to PNG, SVG, JPG, or PDF.

Privacy and permissions

Nitrax Math Bridge reads the equation markup needed for the copy or export action you choose. It processes the equation in the browser and does not collect analytics or transmit webpage content to Nitrax.

FAQ

Which equations can Nitrax Math Bridge detect?

It detects equations rendered with KaTeX, MathJax, and native MathML. A page may use another display method, so not every visual formula on the web is necessarily available to the extension.

Is the Word Online result editable?

Copy for Word (image) is intended for a reliable rendered result in Word Online. It pastes as an image rather than as an editable equation.

Can I keep editing the equation in another notation system?

Choose LaTeX, Typst, MathML, UnicodeMath, or Markdown when you want a notation-based result for the next editor or document workflow.

Move the equation, keep your momentum

When a web equation needs to become part of a document, note, or technical draft, Nitrax Math Bridge gives you a direct choice of output instead of rebuilding it by hand.
