Host a MathML file and share it as a link
Put mathematical markup at a public address — the standard for equations on the web.

Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site
Free to use. Your MML file is live at your-name.99helpers.site in about ten seconds.
What is a .mml file?
MathML is the W3C standard for describing mathematical notation as XML, so equations are real structured content rather than pictures — readable by screen readers, selectable, and scalable. Browser support was patchy for years but is now solid.
What people use MML files for
- Equations in academic and educational content
- Accessible mathematical notation
- Output from LaTeX conversion tools
- Formulas embedded in documentation
What opens a MML file
- Every modern browser, which renders MathML
- MathJax and KaTeX
- LaTeX conversion tools
- Assistive technology, which reads it aloud
How to host a MML file
- 1
Drop your MML file in
Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.
- 2
Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: equations.99helpers.site
- 3
Publish and share
Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.
The same three steps work for any file — see how file hosting works on 99helpers.com.
What happens when someone opens the link
The browser displays the markup. Embedded in an HTML page it renders as properly typeset mathematics.
Why host a MML file instead of emailing it?
Equations shared as images can't be selected, searched or read aloud. Hosting MathML keeps them as real content.
Worth knowing before you publish
- MathML renders properly inside an HTML page; on its own it displays as markup.
- Most people write LaTeX and convert to MathML rather than writing it by hand — it's extremely verbose.
- Browser rendering has improved a great deal; MathJax is no longer always necessary.
MML hosting questions
- Will the equation render?
- Inside an HTML page, yes — every modern browser renders MathML. Opened on its own, you see the markup.
- MathML or LaTeX?
- Write in LaTeX, which is far more pleasant, and convert to MathML for the web where accessibility and selectable text matter.
- Do screen readers handle it?
- Yes — that's a major reason to use MathML rather than images of equations.
