Can not combine. Keeps saying converting to pdf all files are pdf.

Hi queensation​,

Is this the message that you saw when you tried to combine files?

Did you select non-PDF documents (e.g. Word, Excel, JPEG, PNG, etc.)?

As the message indicates, Acrobat can combine PDF documents only.  If you have non-PDF documents, you can use "Create PDF" to convert to PDF first.

Please let us know if you have additional questions.

Thank you.
