Is there a limit on how many PDFs I can merge?
No. Merge as many PDF files as you like. There are no daily limits or file count caps.
Can I reorder pages before merging?
You can control the order by choosing which files to upload first — the PDFs are merged in the order they appear in the file list. Remove and re-add files to reorder them.
