There is no file count limit. You can merge 2, 10, or 50+ PDFs in a single operation. Simply add all the files you need, arrange them in order, and click Merge PDFs.
Drag any file row up or down in the list to instantly reposition it — pages from each source file are merged in the order they appear in the list, from top to bottom. You can also use the ↑ and ↓ arrow buttons for precise step-by-step movement.
