Questions and answers
Are my PDFs uploaded?
No. The files are merged inside your browser and never sent to a server.
Can I merge password-protected PDFs?
Not while they are locked. Open the PDF with its password, save a copy without protection, then merge it.
Is there a watermark or a page limit?
No watermark and no fixed page limit. Very large files (hundreds of MB) can be slow on phones.
