Merge PDFs without uploading them
Select two or more PDFs and Morph joins them into one, in the order you picked. Split works the other way round, one PDF per page.
How to do it
Select the PDFs
Two or more, in the order you want them.
Choose Merge PDFs
It's on the Tools wheel, or under Tools in the app on iPhone and Android.
Done
The merged PDF is saved next to the first file as Merged.pdf.

No limit is set by Morph; it's only bound by your device's memory.
