Image Server and Viewer

Document Engine offers developers a server-based image viewer that can be used by PSPDFKit’s Web, iOS, Android, Flutter, and React Native frontend SDKs. Its server-side rendering guarantees consistent performance for your users, no matter their device. It can also be used for synchronizing images and annotations to your server and across sessions, as well as managing authentication. It can be self-hosted on your own infrastructure.

How It Works

When using Document Engine, you can treat an image file the same as you would any PDF.

  1. Your server uploads the image file to Document Engine.

  2. Document Engine will convert the file to PDF and store it.

  3. You can display the document using the returned document ID.
