iPhone 6s changing camera resolution
I would like to reduce the size of my camera files by reducing the resolution for use on web sites.
iPhone 6s, iOS 10.3.2
If you want to do this without an app, you can email the photo to yourself, before sending it it will ask you if you want tosend the picture(s) as small, medium, large or actual size. Each option reduced the resolution more.
The other option is to use an app to reduce the size, for example: CropSize - Photo Resize & Crop to Exact Image Size on the App Store
