FAQ
What commands are supported?+
KaTeX's range of commonly used commands — fractions, roots, integrals, sigma, matrices, Greek letters, and most common symbols.
How do I paste the result into Word or PPT?+
Save as PNG and insert as an image. Word 2016+ also supports LaTeX math mode if you paste the code directly.
I don't know LaTeX syntax. Where to start?+
Try the Formula Builder tool — clickable buttons let you create fractions, roots, integrals, etc. without learning LaTeX.
PNG or SVG — which is better?+
SVG (vector, infinite zoom) for PDF, print, and web. PNG (better compatibility) for KakaoTalk, SNS, and email.
Can I change formula color?+
Yes — use \color{red}{x^2} style commands. Useful for white-text formulas on dark-mode materials.
Long formulas look too small. Can I make them bigger?+
Adjust the scale when saving as PNG. SVG stays crisp at any size.
