LaTeX equation to PNG and SVG

Type a LaTeX equation, pick a colour and size, and download it as a transparent PNG (with its DPI recorded) or as a vector SVG. The equation is typeset by MathJax in your browser, supports AMS environments and chemical equations with \ce{…}, and works in PowerPoint, Google Slides, Word, Keynote and figure editors.

What it does: Converts a LaTeX equation into a transparent PNG (150–1200 dpi, DPI recorded in the file) or a vector SVG you can paste into slides, Word or figures.
Formula: MathJax 3 TeX input (AMS math, mhchem \ce{…}) rendered to SVG paths; PNG pixels = size at 96 dpi × DPI ÷ 96.
Example: An equation 400 px wide at 96 dpi is 400 ÷ 96 = 4.17 inches wide; exported at 300 dpi the PNG is 400 × 300 ÷ 96 = 1250 px wide and still prints 4.17 inches wide.

How to use the LaTeX equation to PNG

Type or pick an equationWrite LaTeX math without dollar signs, or insert an example such as Michaelis–Menten or the Nernst equation.
Set the styleChoose display or inline style, the colour, the size and a transparent or white background.
DownloadSave a PNG at the resolution you need, or an SVG for slides and vector figures. You can also copy the SVG code.

How it works

The tool uses MathJax 3 with its full TeX input (AMS math, mhchem for chemistry, physics, cancel, color and more) and SVG output with every glyph written as a path, so the SVG needs no fonts. The PNG is drawn from that SVG at your chosen resolution: the size you pick is the size at 96 dpi, and higher DPI adds pixels without changing the physical size. A pHYs chunk records the DPI in the PNG, so Word and PowerPoint place it at the intended size.

Worked examples: from LaTeX to PNG and SVG

Three equations from start to finish. Type each one without dollar signs; the preview updates as you type.

Michaelis–Menten, for a slide. Type v = \frac{V_{\max}[S]}{K_m + [S]}, keep display style and a transparent background, and download SVG. In PowerPoint (Microsoft 365 or 2019 and later) use Insert → Pictures; the SVG stays sharp at any size and can be recoloured.
A reaction, for a figure. Type \ce{6CO2 + 6H2O ->[h\nu] C6H12O6 + 6O2}. The \ce{} command (mhchem) sets subscripts, charges and arrows correctly without extra markup; text above an arrow goes in square brackets.
Two aligned lines, for a document. Type \begin{aligned} \Delta G &= \Delta H - T\Delta S \\ \Delta G^\circ &= -RT\ln K \end{aligned}; the & marks the point the lines line up on and \\ starts a new line. Download a PNG at 300 dpi for Word or Google Docs.

How big is the PNG? The size you choose is the size at 96 dpi; the DPI only adds pixels. An equation 400 px wide at 96 dpi is $400 / 96 = 4.17$ inches wide; at 300 dpi the PNG is $400 \times 300 / 96 = 1250$ px wide and still prints 4.17 inches wide, because the DPI is written into the file.

Frequently asked questions

How do I convert a LaTeX equation to PNG?

Type the equation without dollar signs, choose the size, colour and background, then click Download PNG and pick a resolution: 300 dpi for slides and documents, 600 dpi for journal figures. The PNG records its DPI, so it is placed at the intended size.

How do I put a LaTeX equation in Word or Google Docs?

Download a 300 dpi PNG (or SVG for Word in Microsoft 365) and insert it as a picture. In Google Docs use Insert → Image → Upload from computer. To edit the equation later, keep the LaTeX: paste it back into the tool and download again.

How do I write a chemical equation in LaTeX?

Use the mhchem command: \ce{2H2 + O2 -> 2H2O}. Numbers after an element become subscripts, charges go after the formula (\ce{SO4^2-}), <=> gives an equilibrium arrow and text in square brackets after an arrow is written above it.

How do I insert a LaTeX equation into PowerPoint or Google Slides?

Download the equation as SVG (PowerPoint 2019 and Microsoft 365 insert SVG as a sharp, recolourable picture) or as a 300–600 dpi PNG with a transparent background for Google Slides and older versions, then insert it as a picture.

Is the PNG background transparent?

Yes by default. Switch the background to white if the slide or document needs it.

Which LaTeX commands are supported?

Standard LaTeX math plus AMS environments (aligned, cases, pmatrix…), chemistry with \ce{…} from mhchem, and most MathJax extensions. Text-mode document commands such as \section are not, because this is an equation renderer.

What resolution should I use?

300 dpi is enough for slides and most documents; 600 dpi suits journal figures; 1200 dpi is for line art at very small sizes. SVG avoids the question entirely because it is vector.

Is it free and private?

Yes. It runs entirely in your browser, needs no account, and your equations are not sent anywhere.

Put this equation on a figure, poster or slide

The LabCanvas editor has the same LaTeX equation tool built in: equations stay editable vector outlines next to your plots, structures and labels. Your equation from this page opens in it.
