Can I reorder pages before merging?

Yes — drag files into order, rotate pages, and pick exactly which pages of each file to include.

Is there a file size limit?

No artificial limit — merging happens in your browser's memory, so very large jobs are bounded only by your device.

No — files are combined locally with pdf-lib. Nothing is transmitted, ever.
