How to Reduce Photo File Size on iPhone: 2025 Guide

The storage demands of modern iPhones are high, often going from 1–5MB per image, or even more if it's a Live Photo. It may be possible, though, to solve the problem, like iCloud storage or deleting photos, but the tradeoffs aren't ideal: you have to pay, and then you lose your great memories.

Reducing photo sizes without lowering quality is a better alternative than saving photo storage in the process. If you want to discover some ways to reduce photo file sizes on your iPhone, this guide will explore several methods (iPhone settings, online tools like insMind, and third-party apps) for reducing photo file sizes.

Part1: How to Reduce Photo File Size on iPhone with iPhone Settings

To control the size of photos taken by iPhones there is already a built-in way. Here's how you can do it effectively:

Access the Camera Settings

Here is the step-by-step guide on accessing and changing camera settings to save space:

Step 1: Camera Settings

Hit Settings on your iPhone and scroll down to Camera. From here, you will choose the format.

Step 2: Choose Format

Choose a High-Efficiency format to save space with new captures.

Change to High-Efficiency Format

Under Formats select High Efficiency. This allows the ability to use the HEIF/HEVC format, where photos and videos are compressed to smaller sizes while not losing recognizable quality. This, however, uses traditional JPEG and H.264 formats which are larger, but more compatible with more devices with the Most Compatible option.

Benefits of High Efficiency

If you’re taking Live Photos or 4K videos often, using High Efficiency saves you huge volumes of storage space. This is a long-term solution, not only achievable but optimal for keeping photo quality while keeping storage requirements down.

If you make these adjustments, you can be sure that every photo you capture on your iPhone saves less space, meaning you don't need an external tool in some cases.
