Hi there,

Thanks for contacting pdf.js forums,

Did you add the license key into the WebViewer constructor?

> **[PDF.js Express Viewer Download & Integration | Documentation](https://pdfjs.express/documentation/get-started-viewer/add-license-key)**

Can you provide a screenshot of the error message when the watermarks still show up?

Here is a relevant forum post regarding this issue:

> Hi there, To remove the watermark you must provide a valid license key. If you are using PDF.js Express Plus, you can purchase a license key [here](https://pdfjs.express/pricing). If you are using PDF.js Express Viewer, you can get a free license key on the [profile page](https://pdfjs.express/profile). Note that even with a license key, the watermark will still be displayed on localhost. Thanks! Logan
