A PDF workspace you can keep on your device.
Install the PWA where supported, then explicitly prepare the local tool files for offline use.
Offline resources are not prepared yet. Initial preparation needs an internet connection and downloads the local PDF engines.
What works offline?
Once preparation completes, cached core PDF page tools, previews and editing resources can load without a connection. Processing still depends on device memory and supported input files. OCR and translation depend on language resources that must already be downloaded and on browser support. They are not included in the core offline-ready guarantee.
What still needs connectivity?
Sign-in, cloud documents, teams, signature requests, phone pairing and webpage rendering require a connection. Prepared but undeployed Office conversion is not enabled by installing the PWA.
Your documents are not part of the offline cache
The offline cache stores public application files, not uploaded documents, account API responses or private download blobs. Closing a tool clears its file references; save important results to your device before leaving. Clearing site data or browser storage can remove the offline application files.
Installation support
Use the browser’s install action where available. On browsers without an install prompt, use their supported Add to Home Screen or installation option. This is an installable website, not a separate native desktop application.
