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.

Is the password saved in the recipe?

No. A recipe only records that a protection step exists; you type the password when you run it.

Any change to a signed PDF invalidates its digital signature. Treat the result as unsigned and keep the original.

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

Apply the same steps to many PDFs: rotate, delete pages, watermark, number, clean and protect.
