I submitted a PR adding mobile support and PDF.js integration to this component  
5+ weeks ago, but haven’t received any feedback yet. Since others might find it  
useful, I’m sharing my enhanced fork:

[https://github.com/shortmort37/discourse-pdf-previews](https://github.com/shortmort37/discourse-pdf-previews)

Key improvements:

- Mobile device support (removes the mobile block)
- PDF.js rendering with page navigation and zoom controls
- Thumbnail previews in “New Tab” mode
- Works with PDFs lacking .attachment class (great for migrations)
- Pinch-to-zoom on mobile

I’ve been running this on [59plymouth.net](https://59plymouth.net) for 2+ months with  
converted phpBB content - works great on both desktop and mobile.

Installation: Admin → Appearance → Themes → Install from Git → paste the URL above

PR is still open if the maintainers want to review: [Add PDF.js integration with mobile support by shortmort37 · Pull Request #49 · discourse/discourse-pdf-previews · GitHub](https://github.com/discourse/discourse-pdf-previews/pull/49)
