Hi Birkir!

PDF.js parses a PDF using the HTML5 Canvas element. It does not look at the tag structure of the PDF (probably for security purposes). I believe that if you also download the PDF from the browser, it is the same as 'printing' it from the browser, so it's not the same file that was properly tagged.

Here's an article that goes into better detail about how pdf.js works:

HTH!
