Are my PDF files uploaded?

No. The document is opened and rewritten inside your browser. It is never sent to a server, and closing the tab discards it.

No. The text is turned into a single readable column. Images, columns and tables are not reproduced.

Why is the result empty?

Scanned PDFs contain pictures of text. Run OCR on them first.

JavaScript is turned off. InspireTools processes files in your browser, so the tools need JavaScript to run.
