How to Merge Customs Declarations and Invoices into One PDF

Around every shipment you handle a pile of documents: customs declarations, commercial invoices, packing lists, contracts. Scattered PDFs are a pain to send to buyers and a pain to archive. Merging them into one book in the right order keeps things manageable.

Merging happens entirely in the browser, so sensitive documents with customer details never touch a server. If the result is too large, compress it once more.
