How to reduce photo size on iPhone

Reducing the size of a photo taken on your iPhone is pretty simple. We’ve outlined two methods that you can use to compress a photo. The first involves the use of a built-in iOS feature, while the second one uses a third-party app.

Change camera output format

iOS offers an easy option that lets you adjust the camera format for efficiency. The format is known as HEIC, or High-Efficiency Image Container, and is Apple’s alternative to JPEG. Using this format for the iPhone camera will result in high-quality images that are smaller in size when compared to JPEG files. Here’s how to enable this format on your iPhone.

1) Launch the Settings app.

2) Navigate to the Camera options.

3) Tap on Formats and choose High Efficiency.
