PSE 2023 makes png-files opaque when processing multiple files

[Annette302622292qnj]

I have PSE 2023, when I use the menu option "Process multiple files something" under File, (I have the swedish version), it makes .png-files opaque when I only wanted to change size. So, it basically turns them into .jpg-files instead. I can do it in Paint shop pro, which is 15 years old software, but it can't resize items so for that I must use PSE 2023.  Am I doing something wrong to cause this?

The original png files have transparency, but Process Multiple Files removes the transparency

and they are still saved as png files, is that correct?

What operating system are you using?

Windows 11.

How are you displaying the png files?

I don't understand the question, I look at them in Windows explorer or PSE 2023...

Did you make sure you used the proper png format in the Process Multiple Files dialog?
