DB LabsHow Many Photos Can Each iPhone Hold?
Photo capacity varies dramatically by model. Older iPhones with 12MP cameras produce ~2 MB HEIF photos, so a 128 GB model holds roughly 40,000-50,000 photos. Newer models with 48MP cameras (iPhone 15 Pro and later) produce ~5-7 MB photos, fitting about 15,000-20,000 on 128 GB. The iPhone 17 Pro Max with 2 TB storage can hold over 300,000 photos at 48MP. Using HEIF format instead of JPEG roughly doubles capacity on any model.
Photo Capacity Table: Every iPhone Model
These estimates assume HEIF format, approximately 70% of storage available for photos after iOS and apps, and no video. Real-world capacity will be lower since everyone stores apps, videos, and other data.
| iPhone Model | Camera | Avg Photo Size | Storage Options | Est. Photo Capacity |
|---|---|---|---|---|
| iPhone SE (3rd gen) | 12MP | ~2 MB | 64/128/256 GB | 22K / 45K / 90K |
| iPhone 13 / 13 mini | 12MP dual | ~2.5 MB | 128/256/512 GB | 36K / 72K / 143K |
| iPhone 13 Pro / Pro Max | 12MP triple | ~3 MB | 128/256/512/1TB | 30K / 60K / 120K / 233K |
| iPhone 14 / 14 Plus | 12MP dual | ~2.5 MB | 128/256/512 GB | 36K / 72K / 143K |
| iPhone 14 Pro / Pro Max | 48MP triple | ~5 MB | 128/256/512/1TB | 18K / 36K / 72K / 140K |
| iPhone 15 / 15 Plus | 48MP dual | ~5 MB | 128/256/512 GB | 18K / 36K / 72K |
| iPhone 15 Pro / Pro Max | 48MP triple | ~6 MB | 128/256/512/1TB | 15K / 30K / 60K / 117K |
| iPhone 16 / 16 Plus | 48MP dual | ~5 MB | 128/256/512 GB | 18K / 36K / 72K |
| iPhone 16 Pro / Pro Max | 48MP triple | ~6 MB | 256/512/1TB | 30K / 60K / 117K |
| iPhone 17 | 48MP dual | ~5 MB | 256/512 GB | 36K / 72K |
| iPhone 17 Air | 48MP single | ~5 MB | 256 GB | 36K |
| iPhone 17 Pro / Pro Max | 48MP triple | ~7 MB | 256/512/1TB/2TB | 26K / 51K / 100K / 200K |
How Camera Resolution Affects Storage
The biggest factor in photo file size is camera resolution. Here is how the numbers break down per shot.
- 12MP (HEIF): 2-3 MB per photo. Found on iPhone SE, iPhone 13, iPhone 14 standard models.
- 24MP (HEIF): 3-4 MB per photo. The default output on 48MP iPhones (pixel-binned to 24MP for most shots).
- 48MP (HEIF): 5-7 MB per photo. Full resolution on Pro models and iPhone 15+, only used when shooting in 48MP mode or ProRAW.
- 48MP ProRAW: 50-75 MB per photo. Professional format available on Pro models. Dramatically increases storage consumption.
HEIF vs JPEG Impact
Switching from JPEG (Most Compatible) to HEIF (High Efficiency) in Settings > Camera > Formats roughly halves file sizes with no visible quality difference. On a 256 GB iPhone, this means the difference between storing 36,000 photos and 72,000 photos. Always use High Efficiency unless you have a specific reason to need JPEG files.
Which Storage Size Should You Choose?
128 GB: Light Users
Suitable if you take fewer than 50 photos per week, do not shoot much video, and use streaming services instead of downloading content. With a 48MP camera, 128 GB fills up faster than you might expect. Regular cleanup with Swype Photo Cleaner helps keep storage manageable.
256 GB: Most People
The sweet spot for most users. Enough room for 20,000-35,000 photos, several large apps, downloaded content, and years of messages. This is now the base storage on iPhone 16 Pro and iPhone 17 models.
512 GB - 1 TB: Heavy Shooters
Best for people who shoot lots of 4K video, use ProRAW photography, or want to keep years of photos on-device without relying on iCloud optimization. Content creators and photographers should start at 512 GB minimum.
2 TB: Professionals
New with iPhone 17 Pro Max, 2 TB is designed for professional video production, ProRAW workflows, and users who want everything stored locally. Most consumers do not need this much storage.

The Bottom Line
The number of photos your iPhone can hold depends primarily on three things: storage capacity, camera resolution, and file format. Newer iPhones with 48MP cameras produce significantly larger files, which is why Apple has been increasing base storage sizes. Use HEIF format, clean your library regularly, and choose a storage tier that matches your shooting habits. For most people, 256 GB with High Efficiency format provides ample room for years of photos.
