Why iPhone Photos Are Large

Modern iPhones capture high-resolution images with advanced features like:

• HDR (High Dynamic Range)
• Deep Fusion processing
• Live Photos
• 4K image capture

While these improve quality, they also increase file size—often between 2MB to 10MB per photo.

How Photo Compression Works

Photo compression reduces file size by:

• Lowering resolution (dimensions)
• Adjusting image quality
• Changing file formats (JPEG vs HEIF)
• Removing unnecessary metadata

The goal is to balance quality vs size, depending on your use case.
