Merge PDF combines several documents into a single file in the order you choose. Bring together invoices, chapters or scanned pages without installing anything — the whole merge runs in your browser with pdf-lib, so your documents are never uploaded.

Rearrange the files with the up and down controls until the sequence is correct.
Export to combine everything into one PDF and download it.

No. This tool runs entirely in your browser — your file is processed on your own device and never leaves it. The only network request is an anonymous usage counter.
