A free, private LaTeX editor that runs in your browser

TeX Editor Online is a free and open-source LaTeX editor and viewer. It compiles your document to PDF locally with WebAssembly, so your source and output stay on your device and are never uploaded. Use the full editor to write accessible, vector-graphics PDFs with best-practice linting, or switch to Quick View to turn an existing .tex file into a PDF in a few clicks.

What it does

Frequently asked questions

Is it really free, with no account?

Yes. It is free and open source under AGPL-3.0, with no sign-up and no installation.

Is my document private?

Yes. Compilation runs locally in your browser. Your TeX source and PDF are never sent to a server.

How do I get an accessible, tagged PDF?

Begin the document with \DocumentMetadata{pdfstandard=ua-2, lang=en-US, testphase={phase-III}}. The built-in templates already do this, producing structure tags for screen readers.

Why does it prefer vector images?

Vector formats (SVG, PDF, EPS) stay sharp at any size and print cleanly. The editor flags raster images such as PNG and JPEG and suggests a vector alternative.
