Currently I only have my IPhone to take photos, and only an IPad to browse, no PC no more.
I am very pleased with the quality of photos the IPhone delivers but unfortunately the resizing possibility I have right now, is taking a lot away from the sharpness.
I am using an App called “Image Size”. With it I can go down to the maximum allowed size of 800 x 600 pixel, but the crisp, sharp appearance of the original photo is lost then.

Can anyone point out a way to keep the quality of the photos but get down to the required forum size?
I would very much appreciate any help.

Thank you!
