How to Change Resolution of a Picture on Android Online and Offline

Resolution is essential to improve picture quality. However, it does not mean that you always need the highest photo resolution. The higher the photo resolution, the larger the file size.  When it comes to Android phones, the photo resolution is usually determined by the camera technology. Some high-end smartphones, for example, can shoot photos with ultra-high resolution. The downside is that you cannot upload these photos to social media due to the large file size. This guide shows you how to change the resolution of a picture on Android devices.
