What the Math Formula Renderer does
- LaTeX to image: Render inline math
\( a^2 + b^2 = c^2 \)
or display math$$ \int_0^1 x^n\,dx = \frac{1}{n+1} $$
. - PNG or SVG export: Raster for quick sharing or vector for infinite sharpness. Set scale for slides and PDFs.
- Theme and background: Light or dark. Transparent background for clean overlays.
- Equation numbers: Auto number display equations to match academic style guides.
- Fonts and sizing: Pick a base size. Symbols, fractions, sums, and integrals scale consistently.
- Error feedback: Inline hints highlight the first LaTeX issue so you can fix fast (clean pasted text first with the Whitespace Cleaner).
- Quality of life: Live preview, Copy, Download, and quick shortcuts. Compare exported versions with the Code Diff Checker when collaborating.
Quick start
- Open the Math Formula Renderer.
- Paste a formula. Example:
\frac{1}{\sqrt{2\pi\sigma^2}} e^{-\frac{(x-\mu)^2}{2\sigma^2}}
. - Choose inline or display mode. Toggle numbering if needed.
- Select PNG or SVG and set scale. Pick transparent background for layered graphics.
- Click Download or Copy. Paste into Slides, PowerPoint, Notion, Markdown, or your CMS. Add references with the BibTeX Converter.
Popular LaTeX examples that render well
- Fractions and roots:
\displaystyle \frac{1}{\sqrt{2\pi\sigma^2}} e^{-\frac{(x-\mu)^2}{2\sigma^2}}
- Integrals and sums:
\displaystyle \int_{-\infty}^{\infty} e^{-x^2}\,dx = \sqrt{\pi}
and\displaystyle \sum_{k=1}^n k = \frac{n(n+1)}{2}
- Matrices:
\displaystyle \begin{bmatrix}1 & 0\\0 & 1\end{bmatrix}
- Aligned equations:
```
```\begin{aligned} E &= mc^2 \\ F &= ma \end{aligned}
- Piecewise:
```
```\displaystyle f(x)=\begin{cases} x^2 & x \ge 0 \\ -x & x < 0 \end{cases}
Before you export - clean surrounding text
For tidy posts and handouts, remove stray spaces with the Whitespace and Formatting Cleaner, strip extra blank lines with Remove Empty Lines, check caps with the Case Converter, and confirm length limits with the Word and Character Counter. If you embed data blocks or settings, format them with the JSON Formatter.
Accessibility and baseline tips
- Alt text: When you embed images, add brief alt text like integral from 0 to 1 of x to the n so screen readers have context.
- Baseline alignment: For inline PNG, set
vertical-align: middle
or use SVG for smoother alignment in browsers. - Theme contrast: Pick the theme that matches your site. Use transparent background over solid brand colors.
Why images instead of raw LaTeX
Many CMS and LMS editors strip TeX markup. Images preserve spacing, baselines, and line breaks across platforms. SVG keeps equations sharp at any size. PNG is ideal for quick sharing or platforms that require raster graphics.

Troubleshooting
- Formula does not render: Check unbalanced braces
{ }
and missing backslashes. The inline error points to the first issue (inspect odd glyphs with Symbol & Character Info). - Too small: Increase the scale slider or pick SVG for vector sharpness.
- Color mismatch: Switch theme or use a transparent background and let your slide theme color the canvas behind it.
- Odd characters after paste: If you pasted from a PDF, clean the text with the Whitespace and Formatting Cleaner or inspect glyphs with Symbol and Character Info.

Frequently asked questions
- Is the Math Formula Renderer free
- Yes. It is free for normal use and there is no sign in.
- Do you upload or store my formulas
- No. Rendering happens in your browser with MathJax. Your text stays on your device.
- PNG or SVG, which should I choose
- Use SVG for vector sharpness on web and slides. Use PNG for quick sharing or when a platform requires raster images.
- Does it support AMSMath environments
- Yes. Common environments like
aligned
,bmatrix
, andcases
work well. - Can I number equations
- Yes. Enable numbering for display equations and the tool will add sequential numbers.
- Will this help with academic posts
- Yes. Combine rendered equations with clean references from the BibTeX to Citation Converter and run a final check with the Plagiarism Checker.
