Will this generate PDF files on server and take space?

I saw the video WooCommerce PDF Builder for Invoices – Packing Slips – Delivery Notes – Shipping Labels – YouTube

Looks great and exactly what I need.
I just want to make sure that it will not keep these PDF on my end all the time.
I just prefer to regenerate them in worse case. customer already should have them stored in their email, and it is also stored on my email provider. no need to include these files also on wordpress
