WHAT IT DOES

Build the equation, see it, then copy the exact source.

Write a LaTeX math expression with helpers for common structures and symbols, inspect a live local preview, and copy it bare or in the wrapper your document expects. The editor renders with KaTeX in your browser; it does not compile a TeX document or generate a PDF.

Why use it?

Use it to compose a mathematical expression and check its local rendering before pasting it into a document that supports LaTeX math.

How to use this tool

  1. Type an expression or use a structure helper. For example, use the fraction helper to place a numerator and denominator in separate braces.
  2. Check the preview for unsupported commands and choose the bare, inline, or display wrapper expected by your destination.
  3. Copy the LaTeX and verify it in that destination. This editor handles equations, not complete .tex documents, packages, or PDF compilation.

Details and limitations

  • Insertion helpers add fractions, roots, powers, subscripts, sums, integrals, matrices, cases, and frequently used symbols without making you remember every command.
  • The wrapper setting controls what Copy LaTeX returns: a bare expression, inline math, or display math. The preview follows the same inline or display choice.
  • Dropped or pasted .tex fragments are read locally. Full documents, packages, shell escapes, and custom compilation steps are outside this equation editor.
  • KaTeX supports a broad mathematical subset of LaTeX, but it is not a complete TeX engine; unsupported commands are reported beside the preview.

COMMON QUESTIONS

LaTeX Equations questions

Does this generate a PDF?
No. It edits and previews mathematical expressions. There is no server-side compiler, shell escape, package download, or PDF generation.
Can I paste a complete LaTeX document?
The editor is intended for equations and math fragments. Document classes, packages, page layout, references, and custom compilation are not interpreted by KaTeX.
Which wrapper should I copy?
Use bare source when another editor supplies the math context, inline for an equation inside a sentence, and display for an equation on its own line.
