Hi there,

Thank you for contacting pdf.js express forums,

For the hyperlinks in the PDF, you can see them as an annotation, for example in the demo site: [PDF.js Viewer Demo | PDF.js Express](https://pdfjs.express/demo)

And these are types of link annotations we support:

> **[Create Annotations in JavaScript PDF Viewer | PDF.js Express SDK](https://pdfjs.express/documentation/annotation/add-link-to-annotation.8#programmatically-add-hyperlink-to-existing-annotation)**

Please note that the above guide is for express Pro, and the Viewer does not support link annotations: [Internal links don't work in PDF.js Express viewer - #3 by system](https://pdfjs.community/t/internal-links-dont-work-in-pdf-js-express-viewer/1168/3)

Best regards,  
Kevin Kim
