Order, and what carries over
Files are merged in the order shown, and dragging them changes it. Within each file the pages keep their own order — to interleave two documents you need to split them first.
Page content, embedded fonts and images all carry across intact. What does not: form fields lose their interactivity, and links pointing to pages inside their own file may end up pointing at the wrong page once everything is renumbered. Bookmarks from the individual files are not merged into one outline.
Why the result is roughly the sum
Merging copies the page content across; it does not re-compress anything. So a 4 MB and a 6 MB file give roughly a 10 MB result, occasionally a little less where the same font was embedded in both and can be shared.
If the total is too large for an email, compress the images before merging rather than after — there is more to work with.
Frequently asked questions
Can I change the order?
Yes — drag the files into the order you want before merging. Pages inside each file keep their own order.
Do form fields still work afterwards?
No. Fillable fields lose their interactivity when pages are copied into a new document. Fill the form first, then merge.
Is there a file size or page limit?
No. Nothing is uploaded, so the constraint is your machine’s memory rather than an upload cap.
Are my documents uploaded?
No — which matters, since the documents people merge are usually contracts, invoices and scans of identification.
