Merge PDF on Mac: built-in options vs this tool
In Preview, open the first PDF, show thumbnails (View → Thumbnails) and drag the other PDF files into the sidebar where they should go, then save. It works but gets fiddly with many files.
It works in Safari, Chrome and Firefox on any Mac with nothing to install, including Apple-silicon and older Intel Macs.
Private by design
Your file is processed by your own browser, in memory. It is never uploaded, stored or seen by anyone, and the page’s security policy blocks it from sending data to other servers.

Is there a limit on files or size?
