Can someone please help to show an example of how to use “insertBlankPages” to add a blank PDF page to the end of the current PDF document?

Hi there!

Unfortunately PDF.js Express does not support any document manipulation, so the `insertBlankPages` won’t actually work.

If you need to support this you can check out the our sister product, [PDFTron WebViewer](https://www.pdftron.com/webviewer). It supports adding pages as well as many other features.

PDFTron WebViewer actually shares the exact same API as PDF.js Express, so switching over is easy.

Thanks!
