Is there a native OS feature to compress images?

Question

Java

There is a bulletin board application on the webview. When publishing a new ad, you need to compress them to reduce loading time and speed up the application (why upload 2600 * 5000 pixels when hd resolution is enough?). How to do it in android studio? Is there something similar for ios?

Answer 1

what you are going to compress, all formats are already arranged so that you won’t compress them too much, a maximum of a couple of percent.
You can load and display small resolutions first, and then when large images are loaded, change to them.
