How to use
- Type LaTeX math in the input box; the preview below updates immediately.
- Use the symbol palette to insert fractions, roots, integrals and Greek letters at the cursor.
- Toggle display mode to switch between block and inline rendering.
- If KaTeX cannot parse the input, the error is shown in red instead of a broken preview.
Notes
Rendering is done by KaTeX entirely in your browser; nothing is sent to a server. Your input is auto-saved to this device's localStorage. KaTeX implements a subset of TeX: commands that need extra packages, and environments such as tikz, are not supported.
FAQ
- Can I export the formula as an image or code?
- There is no export button. Copy the LaTeX source you typed and paste it into your document or another tool.
- Do multi-line environments such as align work?
- KaTeX supports some environments such as align, but it is not full LaTeX, so complex formulas may render imperfectly or produce an error.
