Frequently asked questions
How is the merge order chosen?
Files are merged in the order presented by the file selection. Check their listed names and select them again if the order is wrong.
Are encrypted PDFs supported?
No. Use valid, unencrypted source PDFs. Keep originals because document rewriting can alter features and invalidate digital signatures.
