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.

Can I use a password-protected PDF?

Unlock it first with the Unlock PDF tool, using its password. Protected files cannot be processed directly.

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

Save selected pages of a PDF as a new document.
