How to Resize a Photo on iPhone: Complete Guide (2025)

Need to resize a photo on your iPhone? Whether you're reducing dimensions for social media, shrinking file size for email, or optimizing images for websites, this comprehensive guide shows you exactly how to resize photos on iPhone.

Understanding Photo Resizing

What Does "Resize" Mean?

Resizing a photo can mean two different things:

1. Changing Dimensions (Resolution)

What it is: Reducing pixel dimensions (e.g., 4032x3024 → 1920x1080)
Result: Smaller file size AND smaller image dimensions
Use case: Social media, web images, thumbnails

2. Reducing File Size (Compression)

What it is: Keeping dimensions but reducing file size
Result: Smaller file size, SAME dimensions
Use case: Email attachments, file size limits, storage
