FAQ

Can I change the order of PDFs before merging?
Yes. Reorder files in the list before merging. Pages from each file are appended in that order.
Will merging reduce quality?
No. Merge combines existing page content without re-compressing images, so quality stays the same as your source files.
Do I need an account?
No. Merge is free and runs entirely in your browser with no sign-up required.
