Offline batch conversion for Windows is in development. Leave your email and you'll be the first to know when the installer is ready — one email, nothing else.
Convert whole folders with no connection at all — the engines ship inside the app.
Queue hundreds of files, use every CPU core and auto-save results to a folder you choose.
Files stay on your machine. No uploads, no accounts, no telemetry on your documents.
Need conversions right now? Use the browser converter — it already does everything privately, in your browser.
