Annotate a Document

Information

PSPDFKit Server has been deprecated and replaced by PSPDFKit Document Engine. All PSPDFKit Server and PSPDFKit for Web Server-Backed licenses will work as before and be supported until 15 May 2024 (we will contact you about license migration). To start using Document Engine, refer to the migration guide. With Document Engine, you’ll have access to robust new capabilities (read the blog for more information).

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.

PSPDFKit for Web sends new annotation data to PSPDFKit Server, which saves it in the 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.
