Frequently asked questions

Is there a limit on how many PDFs I can merge?
No artificial limit — merge as many files as your browser's memory can hold. Everything runs locally, so there's no server-side file cap.
Will merging add a watermark or require an account?
No. Merging is completely free, with no watermark and no sign up, because the file never touches our servers in the first place.
Can I change the order of the pages before merging?
Yes — drag any file up or down in the list before you merge. Pages are combined in exactly that order.
