How to Compress Photos on iPhone: Complete Guide (2025)

Running out of storage on your iPhone? Need to send multiple photos via email? Want to upload images faster? Compressing photos on your iPhone is the solution. This comprehensive guide shows you exactly how to compress photos on iPhone using the best methods available in 2025.

Why Compress Photos on iPhone?

Storage Space

Modern iPhones take incredible photos, but they come with a cost:

iPhone 15 Pro: 5-15MB per photo
iPhone 14: 4-8MB per photo
iPhone 13: 3-6MB per photo

With hundreds or thousands of photos, this adds up quickly. Compressing photos can free up gigabytes of storage space.

Faster Sharing

Email: Most providers limit attachments to 25MB total
Messaging: Large photos take longer to send and receive
Social media: Faster uploads mean less waiting
Cloud backup: Compressed photos backup faster and use less data

Website Requirements

Many websites have file size limits:

Job applications: 2-5MB per file
Profile pictures: 1-2MB maximum
Document uploads: Often 2MB limit
Form submissions: Strict size restrictions
