Questions
Why does this work offline?+
There is no server round trip. The PDF engine runs in your browser, so the network is only needed to load the page.
Are my files uploaded anywhere?+
No. Every PDFOnCall tool runs inside your browser, so the file never leaves your device. That is also why it finishes in seconds instead of waiting in an upload queue.
