How to merge PDF files

Drop the PDFs in. They line up in the order you dropped them, every page visible. Add more at any point.
Check the pages. Drag a page or a run of pages anywhere, even into the middle of another file. Remove a blank or duplicate page with its ×. Rotate the sideways ones.
Merge and download. One PDF. The originals are untouched.

Merging, done properly

Order: The files go in the order you drop them; drag pages to change it. A cover page from one file can sit on top of another.
Pages, not just files: You can leave out a page or two while merging, instead of merging and cleaning up afterwards.
Mixed sources: Scans, photos of receipts and exported PDFs all go into one file. A photo becomes a page the shape of the photo, or A4 or Letter if you prefer.
Size: Nothing is re-rendered, so the merged file is about as big as the parts. For a smaller file, compress the images before adding them.
What carries over: Text, images and links inside the pages. Bookmarks and fillable form fields from the originals are not carried into the merged file.
