when I edit photo's in Iphoto on my ipad2, it decreases the resolution. Why does this happen and does this also happen on a macbook air?

I have made pictures on high resolution with a Canon 100D camera, which means the pictures are 5-6 MB.

But when I edit them on my Ipad2 in Iphoto it decreases the size and resolution of the pictures to about 0.5MB

 

Does anyone know why Iphoto decreases the resolution of my pictures when I edit them?

And does this also happen with Iphoto on a macbook air?

 

Thank you.
