Your files stay on this device. They are never uploaded, not even to us. Check it yourself

Are my files uploaded?

No. The PDFs are read and combined inside this browser tab, and the page's security policy blocks it from sending data anywhere.

Does it keep links and bookmarks?

Page content, links on the page and form fields are kept. The combined file doesn't carry over each file's bookmarks outline yet.

Can I merge password-protected PDFs?

Yes. If a PDF needs a password to open, the tool asks for it and unlocks the file on your device. The password is not saved or sent anywhere. A PDF with only print or copy limits can have them removed for the job. Only do this for files you own or may change.
