Is there a limit on how many PDFs I can merge?

No fixed limit — merge as many as your device’s memory allows. Dozens of typical documents combine without any trouble.

Will the quality of my PDFs change?

No. Pages are copied into the new file exactly as they are — text, images, and formatting are untouched.

Can I merge password-protected PDFs?

Not directly. Remove the password first (most PDF viewers can save an unlocked copy once you enter the password), then merge.

Are my documents uploaded to a server?

No. Merging runs entirely in your browser. Your PDFs never leave your device — a real advantage for contracts and private paperwork.
