Explore the benefits of Document Engine

PSPDFKit Server has been deprecated and replaced by Document Engine. To migrate to Document Engine and unlock advanced document processing capabilities, refer to our migration guide. Learn more about these enhancements on our blog.

After you create a document via upload or URL, you can annotate it via the Web Viewer, Web SDK, or Server APIs. Annotations are automatically persisted in the PostgreSQL database.

1. PSPDFKit for Web sends new annotation data to PSPDFKit Server, which stores it in the database.

2. PSPDFKit Server returns the annotation ID to the Web SDK.
