Hi there!

Are you talking about the PDF.js Express watermark, or an existing watermark in the document?

Hi,

To remove the watermark you must [purchase a license](https://pdfjs.express/pricing) and provide it to the WebViewer constructor.

```javascript
import WebViewer from '@pdftron/pdfjs-express'

WebViewer({
   licenseKey: "YOUR_KEY_HERE",
   ...
})

```

Thanks!  
Logan
