how to merge pdfs in alphabetical order

  1. drop two or more pdf files on the box, or click it to choose them. you can add more files later.
  2. check the page thumbnails. drag pages to reorder them, even between files, and press the cross to drop any page you do not want.
  3. use sort files by name or reverse pages if you want a quick bulk order.
  4. press merge and download merged.pdf.

most scanners and exporters number their files, like invoice-1.pdf up to invoice-12.pdf. plain alphabetical sorting puts invoice-10 before invoice-2. this page sorts names in natural order, so the merged pdf follows the numbering you expect.

files are sorted when you add them. if the order is almost right, move a single file with the arrows, or open the pages view for page-level changes. adding files later re-sorts the whole list by name.

frequently asked questions

does it sort by date too?

no, only by file name. rename files with a date in front, like 2024-03-invoice.pdf, and they will sort by date.

what is natural order?

numbers inside names are compared as numbers, so page2.pdf comes before page10.pdf instead of after it.

can i change the order afterwards?

yes. use the arrows in the files list, or switch to pages view and drag individual pages.
