How can I merge PDF files in the correct order?

Our PDF merger gives you full control over page order with an intuitive drag-and-drop interface. After uploading your PDFs, you'll see thumbnail previews of each file. Simply drag the thumbnails vertically to arrange them in your desired sequence — the file at the top becomes page one of your merged document. This prevents the common error of accidentally placing appendices before the main document. You can also remove unwanted files by clicking the delete icon on any thumbnail. Once you're satisfied with the order, click 'Merge' and download your combined PDF. No more renaming files with numbers or hoping alphabetical sorting works.
