Join PDF Files on Mac

macOS Preview can merge PDFs, but the workflow is fiddly — you have to open a file in thumbnail view and drag pages from the second file across, which often causes confusion. This browser tool offers a simpler approach: drop your PDFs, click Merge, download.

It works in Safari, Chrome, and Firefox on macOS without installing any software. Since everything runs in the browser, it also works on Intel and Apple Silicon Macs equally, and does not require Rosetta or any compatibility layer.

For users who frequently need to combine PDFs on a Mac, this tool avoids the Preview sidebar workflow entirely. You can also bookmark it for quick access — there is no account or login screen to navigate.

The resulting file is a standard PDF that opens in Preview, Acrobat, and any other PDF reader without issues.
