Frequently asked questions
Can I still change the order?
Yes. You arrange the files in the order you want before creating the result.
Are my files uploaded?
No, merging happens in the app on your computer.
Do I need Word to add a Word file?
Word, Excel and PowerPoint files need Microsoft Office. PDFs and images do not.
