Hello t.wilsmann,

Are you see the watermark on localhost? Note that even with a license key, the watermark will still be displayed on localhost. Please also make sure you are using this package: [@pdftron/pdfjs-express - npm](https://www.npmjs.com/package/@pdftron/pdfjs-express)

Best Regards,

Darian
