UNique Issue

I am currently migrating our old website to drupal 8. We have over 1000 PDF’s that need to meed ADA strict standards for screen reader access.

SO we are going to convert our PDF into html first. The good converters break the converted file into numerous .CSS, .JS and image files and folders. Whats the best practice to import them into a page node as html???

Thanks Mitch
