How to change resolution of photos in iPhone 6s+?

Hello, I know that we can change the resolution of videos by going to Settings. I cannot find such option for camera. Is there a way to change the resolution of the camera before taking the photos?

You can't. If you want smaller photo file sizes and dimensions, you need to open up the photo in an app like Pixelmator and then resize it. Keep both or delete the big one.

Thanks. This seems to be inconvenience and time consuming especially when I have thousands of photos. Can it be done automatically in batch? Let's say I put photos that I need to reduce the file size in a folder. Then, an app reduces the file size of all the photos in this specific folder.

That is possible.

I have an Applescript that calls GraphicConverter in the background and processes our company's editorial photos. Part of that process is resizing the images. It's a folder action and it executes any time an image is dropped into the folder.

But Applescript is Mac based so if you have a PC this won't help you. If that is the case, there may be an graphic app out there with a batch processing feature.
