To merge PDFs, open a browser-based merge tool, add two or more files, drag them into the order you want, and download the combined document. It runs on your device, so the files are never uploaded, and pages are copied as-is — no re-compression, no sign-up, no watermark, and no cap on how many you combine.
Merging — combining several PDFs into a single file — is how you assemble a signed contract from its pages, bundle receipts, or join scanned sections into one document. Here is how to do it privately, without sending your files to a server.
Everything happens on your device — the files are never uploaded, and there is no waiting for a transfer.
Pages are copied exactly, so merging never re-compresses or degrades a page. Two things to know: interactive form fields and bookmarks from the source files may be flattened in the combined document, and password-protected PDFs need to be unlocked before they can be merged.

There is no fixed file-count or size limit — merge as many as your device’s memory allows, because nothing is sent to a server. If you also need to reorder or rotate pages within the result, do it in the Organize tool before downloading.
