PNG-to-PNG batch conversion (preserving Alpha Ch.) - michele.bartolettistella - 10-19-2017
Dear Forum,
I need to halve the resolution of about sixty .png pictures, from 600dpi to 300dpi, preserving their Alpha Channel (transparent background).
I tried with XnView, which provides a very complete batch conversion/editing tool, but, ulnluckily, in the new 300dpi files Alpha is suppressed.
What can I do?
Can GIMP work on these several files this way, with a unique batch action?
Thank you.

The BIMP plugin will work https://alessandrofrancesconi.it/projects/bimp/
Just checked with a couple of (made up) 600 ppi png's with transparency.
Add your images, folder or individual, add the 2 procedures, resize and 'change format', set the output destination.

Just tried and verified: Alpha-Channel still is also in the new pictures.
It works!
