I found this android image editor that can do it!
Code: Select all
https://play.google.com/store/apps/details?id=com.iudesk.android.photo.editor
First, I copied all the appropriate images to a separate folder.
Then I opened the app and selected one of the images to save the preselected task from, but not the image.
Then, I determined what I wanted done to all the images. I am still experimenting with this phase.
Then I backed out to the apps opening menu: Choose batch Let's save here.
