What is the largest single PDF file with the most pages you have ever created?

The file transfer protocols, e.g. SSH/SCP or FTP, do not have a maximum size. HTTP, while not designed as a file transfer protocol, is often used to upload files. The protocol does not have a size limit, but most implementations do impose size limits. The content-length HTTP header field can be any number but most web browser and/or web server implementations treat it as a signed or unsigned 32 bit integer, limiting the HTTP POST content to 2 or 4GB. The underlying TCP protocol has a 32-bit sequence number space, but reusing (wrapping) numbers is allowed as long as it doesn’t happen too quickly. In cases where it might happen to quickly (e.g. 40Gb/s Ethernet), there is a TCP option to logically increase the size of the TCP sequence space which is used by modern TCP implementations, so TCP doesn’t impose a limit. But, let’s have some fun and find a practical maximum size. If you have 100Mb/s broadband, that’s a transfer rate of 10MB/s on an uncrowded Internet. You could transfer around 1 TB a day. 1 TB is probably close to the maximum practical limit and it would probably take most of a week because you’won’t actually get 120Mb/s across the Internet from your house.
