Why Merge PDFs Instead of Sending Multiple Files?
Sending 10 separate files is inconvenient for the recipient — they have to open each one, keep track of the order, and they're more likely to miss one. A single merged PDF is easier to email (stays under attachment limits), simpler to print, and looks more professional. Lawyers, accountants, and HR teams merge PDFs dozens of times a week for exactly this reason.
How to Reorder Pages Before Merging
After uploading, the Merge PDF tool shows a thumbnail preview of each document. You can drag them into any order before clicking Merge. If you want to reorder individual pages within a single PDF (not just the documents), use the Split PDF tool first to separate pages, then merge them back in the order you want.
