Equations for Microsoft Word

Write the equation here, in LaTeX or visually. Copy it as MathML, paste it into Word, and it arrives as one of Word's own equations — still editable, with no add-in to install.

Three steps

  1. Write the equation in the editor above — from the toolbar, or by typing its LaTeX. Both stay in step.
  2. Click Copy MathML. The equation goes onto the clipboard as MathML, the standard markup for mathematics.
  3. Paste into Word. Word converts MathML into its own equation format as it arrives, so the result can be edited in Word like any equation typed there.

Rearranged for the mass:

In Word: one of its own equations, editable there like any other.

The conversion is Word's own import doing the work, so it depends on the version you are running. If yours pastes the markup as text instead, insert the equation as a picture, below.

Or as a picture

For a document that will be shared widely, printed, or opened in something that is not Word, a picture is sometimes the safer choice.

PNG, at print resolution

Download PNG above gives a 300 DPI image with a transparent background. The full editor goes up to 600 DPI, with your choice of size and colour.

SVG, sharp at any size

Current versions of Word insert SVG images, which stay sharp however far you zoom in and however large you print.

Keep the LaTeX

Copy LaTeX gives you the source, to keep beside the document or open again in the editor later — a picture cannot be edited, but its LaTeX can.

SVG
\int_0^\infty e^{-x^2}\,dx = \frac{\sqrt{\pi}}{2}
A vector: drawn afresh at every size, so it stays sharp however far it is enlarged or however large it is printed.
PNG, 300 DPI
\int_0^\infty e^{-x^2}\,dx = \frac{\sqrt{\pi}}{2}
A bitmap: a fixed grid of pixels, 300 DPI unless you ask for another — sharp in print at its own size, soft if stretched beyond it. Every program takes one.

Both shown at the same size.

Inside Word, PowerPoint and Excel

fxEditor also comes as an Office add-in: the same editor in a pane beside your document, in Word, PowerPoint and Excel. Write the equation in LaTeX or visually and put it into the document; select one already there to edit it again. For spreadsheets, fxRender turns the formulas on a sheet into typeset equations.

Questions

Why not just use Word's own equation editor?

If you are happy in it, do. This is for people who think in LaTeX, who want suggestions as they type, or who need the same equation in Word and on the web — the MathML you paste into Word is the same MathML a web page can show.

Does it work with Google Docs?

Yes — there is a Google Docs and Slides add-on, in preview, that inserts equations as images.

Is it free?

Yes, for non-commercial use: coursework, teaching, research. Equations made for something you sell — a book, a course, a product — need a licence. How licensing works.

Try it on the real thing

The full editor is on the home page, with suggestions as you type, history and every export format. It is free for non-commercial use — study, teaching, research or a personal site. Building it into something you sell needs a commercial licence.
