VisualMathEditor review
A free, open-source equation editor for web use, embedding or local hosting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
VisualMathEditor is a JavaScript and HTML equation editor for creating and editing mathematical notation. It is suited to individuals and small teams who want a free tool in a browser, or prefer to download and run an editor locally or host it on their own site. Its open-source GNU GPL version 3 licensing also fits users who want to inspect or adapt the software within that license's terms.
The editor's main strength is its support for several equation syntaxes: LaTeX, AsciiMath, MathML and HTML. Symbol menus include more than 730 LaTeX symbols and 210 AsciiMath symbols, while equation samples cover science, chemistry and commutative diagrams. Finished equations can be exported as PNG or SVG images. These capabilities make it useful where equation authoring and image output matter more than a broader document workflow. The editor can be embedded in a website and configured through URL parameters, giving site owners an integration path without requiring a hosted-only deployment.
VisualMathEditor is available for browser use and can also be downloaded for local use or self-hosting. Users can customize editor style and language, and preferences are saved in a browser cookie. The product is focused on equation editing rather than AI-assisted authoring, and its listed support channel is documentation. Choose it for free equation editing, multiple syntax options, image export or control over hosting; consider another tool if your priority is broader support or capabilities beyond editing mathematical notation.
