Merge PDF files
Choose two or more PDFs, arrange their order and create one combined PDF.
At a glance: Input: 2–50 PDFs · Output: 1 PDF · Order follows the list · Original files unchanged
Files stay on this device.
You can also drop PDFs here.
The file list controls the page order
Choose between two and 50 PDFs. Use the move buttons to put the files in the required order; every page from the first listed file is written before every page from the second, and so on.
The selected files are read together in this browser tab. SnackPDF can stop before processing when their estimated memory use is unsafe for the device.
The combined file is a rewrite
Merge creates one new PDF rather than attaching the originals unchanged. Document-level bookmarks, forms, annotations, links, metadata and other structures may change or disappear, so check the result as well as its page order.
