It is delivered as a Docker container that you deploy on your own infrastructure. Your PSPDFKit-powered apps then connect to it.
The server requires a PostgreSQL database as well as dedicated file storage, using either a local Docker volume or any S3-compatible object storage.
PSPDFKit for Web
PSPDFKit Server pre-processes uploaded documents into a format that PSPDFKit for Web can render and stores annotations. PSPDFKit for Web intelligently downloads pages on demand so even large documents can be browsed quickly.
More information can be found in the PSPDFKit for Web guides.
As with PSPDFKit for Web, PSPDFKit Server stores uploaded documents and annotations. PSPDFKit for Android, iOS and Web connect to PSPDFKit Server to synchronize annotations and download documents.
More information can be found in the guides for each platform.
Users upload documents to your backend, which simply forwards the uploaded PDF file to PSPDFKit Server and receives a document identifier. In your server, you only have to store this identifier - we store the PDF document, its annotations and meta information.
