Hi there,

PDF.js Express does not support merging the XFDF into the document on the client. To do this, you would have to use the [PDF.js Express REST API.](https://pdfjs.express/documentation/utils)

Specifically, you would need to use the [merge endpoint](https://pdfjs.express/documentation/utils/merge).

You can find a full end to end example [here.](https://pdfjs.express/documentation/use-case/upload-download)

If you have any more questions, please feel free to open a new topic.

Thanks!  
Logan
