About the Merge PDF
PDF has no native concept of combining separate files into one — every PDF is a self-contained object structure, so merging means actually parsing each document's page tree and reassembling them into a single new file, not just concatenating bytes. This is why a scanned contract, a signed cover page, and a set of exhibits usually arrive as three separate PDFs even though they belong together for filing or emailing.
This tool lets you drag in up to 20 PDFs, reorder them into the sequence you want before merging, and combine them into one document — the common case being assembling a multi-part application packet, stitching scanned pages back into one file, or combining several reports into a single document for a client or reviewer.
