Two Files, One Clean Document
Plenty of everyday tasks come down to stitching two PDFs together: a cover letter and a CV, a form and its attachment, a quote and its terms, two halves of a scanned document. Merging them into one file means a single thing to send, sign or file β and it always opens in the right order, which loose attachments often don't.
Add the files, drag to set the order, and download. There is no limit imposed and no quality loss: the pages are copied across exactly as they are into one new document.

The files are combined on your device with pdf-lib β page for page, into a single PDF. Nothing is uploaded, so even sensitive paperwork stays private.
