The simplest and quickest way to reduce photo file size on iPhone is within its Settings app. With this method, you can choose the format for all of the photos you take with your iPhone camera. The thing with iPhones is that they are usually set in the most compatible format, which, in turn, will save photos taken in large sizes.

This kind of camera setting will not reduce the quality of the images, but it will save you lots of space on your iPhone.

您可以在“相机设置”中通过以下方法减小文件大小：

Step 1. On your iPhone, go to Settings, look for Camera, and choose Formats.

Step 2. At the top of the screen, choose High Efficiency. This format allows you to have the smallest photo size without reducing quality.

Step 3. To further shrink the size of your image files, tap Pro Default and choose HEIF Max up to 48 MP. This will limit your photo size to approximately 5 MB.
