I’d love to be able to load PDF data in too. I guess you’d need a PDF reader that could generate bitmap data for a texture at runtime. It’s definitely possible to load in a folder of JPGs etc and use those dynamically. I wrote some C# functionality for that a while back using USharp to run the code in UE4. Adding the PDF conversion too would be a cool idea.

You can read directly pdf in cef, by recompiling source code for cef part.
I don’t have experience with specific plugin creation, but I used that procedure last year and works well.
or you can setup a small web server with pdfjs or js reader and setup that in web browser
​​​​​​First option is better of course.
It would be nice to create a small plugin with pdf reader (maybe starting from cef, like blui).

I found my old video on LinkedIn:

—EDIT—

Alternatively you can setup as said in this topic [Credits to user eray_ozr]:

I find a javascript which works perfectly with UE4 Native Web Browsers. Maybe you can look it.

Quick Instruction:

• Download “Viewer JS” ViewerJS Get ViewerJS
• Install Wamp (you can use another server)
• Create a folder in “www” with a name which you desire (mine is PDF_Viewer)
• copy “ViewerJS” folder and its contents from zip to created folder in www
• Create another folder in PDF_Viewer (or what you call your first created folder) (mine is PDFs)
• start wamp
• Point UE4 Web Browser Widget to “localhost/PDF_Viewer/ViewerJS/#…/PDFs/file.pdf”

NOTE:
With this JS, you can show “.pdf / .odt / .ods / .odp” files

ODT = Open source version of .docx. Word can export
ODS = Open source version of .xlsx. Excel can export
ODP = Open source version of .pptx. Power Point can export.

this JS does not require scr script html tags. But URL must contain “#…” after “ViewerJS” point. This syntax will load js and go to your document.
if you use it with “a href=”#" you need to write just URL with #…

License of this JS is Apache 2.0

Load time takes some seconds depends on your document.
