Hi!

You can export the annotations and the document for use on your server.

The flow is basically this:

[Save the document as a blob and send it to your server](https://pdfjs.express/documentation/basic-operations/save-document/blob)

[Save the annotations as XFDF](https://pdfjs.express/documentation/annotation/import-export) and save them to your database

The next time your user loads the document, grab the XFDF annotations from your database and [import them into the viewer](https://pdfjs.express/documentation/annotation/import-export)

Thanks!  
Logan
