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. If you are using PDF.js Express Viewer, you can get a free license key on the profile page.

Note that even with a license key, the watermark will still be displayed on localhost.

Thanks!
