Merge PDFs into a single file.
Pick 2-5 PDFs, drag to reorder them and download the merged file. The total page limit covers book-sized documents; if you pass it, the message names the limit.
Frequently asked questions
How many PDFs can I merge at once?
Between 2 and 5 files. The page ceiling is high enough to take a whole book; if the total goes past it, or past the size limit, the job is refused with a clear error code rather than half-done — and the message names the limit, in pages or in MB.
Is the order of the files kept?
Yes. Pages are added in list order, and you can drag the list into the order you want. Nothing is dropped along the way, images included.
Do I need an account to merge?
No. Merging is one of the free tools: no sign-up, no credits. Whatever you upload is deleted within an hour.
