What is best format to use images (png,jpg) in iOS?

ios, uiimage, uiimageview, xcode

Solution

The format to use images is the `PNG-24` file format, since it provides the highest quality image per `pixel` in the lowest file size. Also, in ios development, png is favored because of the multiple formatting and optional editing.

Most importantly, PNG is a lossless compression formatt, that means it compresses images without losing any quality.

Problem

I'm using a background image, and I would like it to weigh little without losing quality. I found this option in Xcode. `Project-> Packaging -> Compress PNG Files` This would help me to improve file sizes?
