It was brought to my attention that my previous answer was not complete.
WebViewer does support files greater than 2GB if it’s loading XOD files or WebViewer Server. You can use docpub (https://www.pdftron.com/documentation/cli/guides/docpub) to convert PDF to XOD files and you can read more about WebViewer Server here: https://www.pdftron.com/documentation/web/guides/wv-server-deployment.
In addition to that, just want to emphasize that we are also working on adding support WebViewer for arbitrary file size without the need for WebViewer Server or XOD optimization, but don’t have a timeline for it yet.
