What are you really trying to ask? I'm not sure whether to answer how to convert data to a PDF format or how to write an ajax request that will send data to the server and wait for a response.

The first things that come to mind for me are the ignore_user_abort and register_shutdown_function functions. I don't like the idea of having the users controlling the speed at which documents are processed though. It opens me up for denial of service attacks and bogged down performance.

I would rather use something that requested a "ticket" or UUID from the server, then uploaded the data using that ticket, ending that request right there. The data wouldn't be processed immediately though, it would just return a successful upload message and tell the browser it was ok to start sending ajax requests including that ticket requested earlier to see if the document had been processed yet.

Depending on which OS is processing requests, an automated task or a cron job would be used to process the data in batches.

When the AJAX request was made, it would either be answered with a link to download the resulting file, or some statistics about how many files are ahead of them to be processed and an estimated time until comletion based on the batch size and time frame of the cron/AT which will probably be in 60 second intervals.
