Your built-in Photos app lets you crop but not resize to exact pixel dimensions. For passport photos (600×600), visa photos (2×2 inches at 300 DPI), or social media specific sizes (1080×1350), you need precise control.
The tool handles aspect ratio locking automatically. If your photo is 4:3 and you need 4:5, it will crop or letterbox as needed.
iPhone photos are 3-8MB each. Sending 10 photos = 30-80MB attachment, which most email servers reject. Quick compression workflow on your phone:
10 photos at 5MB each (50MB total) → compressed to ~10MB total at 85% quality. Well within email limits.
Each platform needs different proportions. On your phone:
Your phone's built-in editor can crop freely but rarely supports locked aspect ratios or exact presets. The browser tool gives you precise control.
When you need to do multiple edits to a photo on your phone, follow this order:
This order minimizes processing time (crop reduces pixels first) and maximizes quality (compress only the final result, not intermediate steps).
