1. Choose PDFs
On this device · no upload
Choose the PDFs to combine.
2. Arrange files
Drag files or use the up/down buttons to order documents. Page order inside each file is preserved.
3. Merge PDFs
Select Create PDF. Original page sizes are retained, including mixed orientations.
4. Save the result
Download and check document order and the total page count.
Example: merge two documents in a chosen order
Select the two-page sample A and one-page sample B below. Move B to the top and merge: the result has three pages in the order B1 → A1 → A2. Different original page sizes are retained, so inspect each page.
Merging versus organizing pages
Merging changes file order while retaining the order inside each file. To move or remove individual pages afterwards, open the result in Organize pages. Originals are unchanged; keep them until you have checked the result.
