How merging works
Each file is read in the browser and its pages are copied into a new PDF in list order. The original files on your device are not changed.

Questions
Can I change the order before merging?
Yes. Use Up and Down on each file. The merged PDF uses that list from top to bottom.
What happens to password-protected files?
They are rejected. SizeUply does not unlock encrypted PDFs.
Are PDF files uploaded?
No. SizeUply reads the PDF in your browser and creates the new file there. The PDF is not uploaded for processing.
