Current phones have a very high image size (in pixel dimensions). However, when you zoom in to 100%, you'll probably find that the actual image resolution is poor there (little contrast between neighboring pixels).
In addition, current standard camera apps do not allow to pick a reduced megapixel dimension (like my old Huawei Android 8.0 phone did).
So to reduce the waste of storage capacity, I'd like to down-scale camera shots mostly automatically.
The problem does not only apply to still images, but also to videos: For example when I record a few seconds of screencast to demonstrate some issue, the video is multiple MB, too large for an E-mail attachment in most cases.
Is there an app that can do that, or at least help doing that? The standard tools seem unable to do that.
