FAQ
Are my PDFs uploaded?
No. Files stay in browser memory only—check the Network tab; no PDF payload is sent.
Will merge change my invoice content?
Flat PDFs keep page content. Document-level bookmarks/forms may drop—verify the download before deleting originals.
Password-protected PDFs?
Usually not supported—you'll see an error. Unlock the PDF first.
