SwiftLaTeX compiles the PdfTeX and XeTeX LaTeX engines to WebAssembly so LaTeX documents can be compiled entirely in the browser, exposed as a JavaScript library you embed via a script tag. It also provides an optional WYSIWYG browser-based LaTeX editor that lets users edit PDF output directly, though that part is still a work in progress.

Use cases

• compile latex documents in the browser without a server
• wysiwyg latex editor that edits pdf output directly
• embed pdftex or xetex in my own web page
• generate pdf from latex source in javascript client-side
• online latex editor that runs offline with local computation
• run xetex in webassembly for chinese japanese documents

When to choose

• You need LaTeX compilation to happen fully client-side with no server round-trips
• You want to drop a TeX engine into any webpage with a single script tag and a simple async API
• You need output identical to TeX Live or MiKTeX inside a browser app, including CJK and TrueType font support via XeTeX

When to avoid

• You need a complete native TeX Live/MiKTeX toolchain with shell-escape, packages installation, or full ICU locale-aware line breaking
• You require a fully polished WYSIWYG LaTeX editing experience, which is still marked as work in progress
• Your users are on constrained devices, since the wasm engine runs roughly 2x slower than native binaries and template downloads can take minutes
