Compress image with ci 4 library removes png transparency and Incorrect APP1 Exif

I am using compress image from codeigniter 4 library with below code :

Code:

\Config\Services::image()->withFile($this->request->getFile('storeimage'))->reorient()->save('images/store/test.png', 70)

But it removes transparency png image. Can i compress png image without losses the transparency in ci 4?

and also for some image i hit error below :
("exif_read_data(php3CBA.tmp):Incorrect APP1 Exif Identifier Code")
