TeX Viewer Online in-browser

View your TeX documents in any browser, no software needed. Compiles locally with WebAssembly; nothing is uploaded.

1. Engine

XeLaTeX pdfLaTeX

Which one should I choose?

Not sure? Keep XeLaTeX (the default). In this in-browser engine it handles fonts most reliably.

XeLaTeX	Recommended default. Uses vector fonts directly, supports system or OpenType fonts (`fontspec`) and full Unicode.
pdfLaTeX	Slightly faster, but it can fail when a document needs a bitmap font it has to build on the fly, which is not possible here. If you get a font error, switch to XeLaTeX.

2. Files

Live edit with VS Code

Auto-compile when a file is saved

How the live workflow works

Click Open a folder and choose your project folder. Then open the same folder in VS Code (use the Open VS Code button, then File, Open Folder in vscode.dev).

Edit and save in VS Code. This tool watches the folder and rebuilds the PDF automatically on each save.

Idle. Add a .tex file to begin.

First compile loads the engine and a bundled TeX Live (about 125 MB), cached by your browser afterward, so later compiles are quick. Everything runs locally with no server. A desktop browser is recommended for the first load.
