The App DOES NOT WORK as advertised!!!

This app downloads your files and keeps them THE EXACT SAME SIZE as the original. It will not downsize my PNG images from 300 dpi to 72 dpi. While I like this developer’s Image Size App (though DPI and Image Size should be merged into a single app) this one is completely useless!

Response from developer

Thank you for your feedback. The app only modifies the DPI value stored in the image metadata and does not change the image size.

На фиг

Это приложение останется с вами навсегда! Вы его не сможете удалить!

Darkened the original photo

I use both apps but upon paying £14.99 to remove ads I put in my photo only to find the image it threw out was darkened. This is not good. Unlike its pixel app it offers no delete initial photo.
