pdftoexcelnow is a Progressive Web App (PWA). That means you can install it like a real app from the browser — no app store, no download — and use it on iPhone, Android, Windows, macOS and ChromeOS.
The converter UI loads even with no internet. If you pick a PDF while offline, it lands in a local upload queue stored in the browser's IndexedDB.
On Chrome, Edge, Brave and Android the queue uses the browser's Background Sync API, so the moment your device reconnects, queued uploads are sent automatically — you do not have to reopen the tab. On Firefox and iOS Safari (which don't yet ship Background Sync), the queue flushes the next time you open the app.
The PWA can also receive push notifications when long batches finish. Set up push notifications →
The PWA never reads your files until you select them. Files are uploaded over HTTPS to pdftoexcelnow.com and deleted after conversion. We do not access your camera, microphone or contacts.
