Consistent features and rendering across mobile apps

Customers have two deployment options for mobile use cases: with an external server and on-device.

Native apps run on iOS and Android using the same engine as the web version, not a separate native port. Features and rendering stay consistent on both web and mobile. All files are bundled into the app, so it works fully offline: no external server calls, and no document ever leaves the device.

Encrypted Storage

External server

Run PDF Viewer on an external server and embed it into a mobile app

On-device

On-device

The app serves content locally on the device and shows it in a native view

Powerful PDF editing and annotations with PDF Viewer

Fully offline document access and processing

Fully air-gapped deployment can be practical when end users need to handle documents in low-connectivity environments. They can still view and edit PDFs when travelling, in a basement, in a secure facility, in a vault, on a construction site, or anywhere with weak or no connectivity.
