**Which product are you using?**

PDF.js Express Viewer

**PDF.js Express Version**

v8.7.5

**Detailed description of issue**  
I obtained a free license using my company email address, but during development on localhost, a watermark labeled “[pdfjs.express](http://pdfjs.express)” appears.  
Does the free license always include a watermark? If so, I only need the following features. Could you issue a custom license enabling just these functions? Please also inform me of the license fee in that case.

Required features:  
・Page-by-page thumbnail display  
・Page zoom in/out  
・Full-screen display mode  
・Page panning  
・Language (Japanese only)

Thank you for your assistance.

**Expected behaviour**  
(I’d like to remove ‘[pdfjs.express](http://pdfjs.express)’ watarmarks)

**Does your issue happen with every document, or just one?**  
every document

**Link to document**  
n/a

**Code snippet**

Hi there,

The demo license will always include the watermark. To remove it, you will need a valid license.
