How Many Photos Does 1GB Hold on iPhone?

By Jack Smith · Updated March 8, 2026

Photo Size by iPhone Model and Format

The number of photos that fit in 1GB varies significantly depending on your iPhone model and the file format it uses:

• iPhone 16 Pro / 15 Pro (48MP HEIC): ~4–6 MB per photo = ~170–250 photos per GB
• iPhone 16 Pro (48MP JPEG): ~10–15 MB per photo = ~70–100 photos per GB
• iPhone 14 / 13 (12MP HEIC): ~2–3 MB per photo = ~330–500 photos per GB
• iPhone 16 Pro (ProRAW): ~25–75 MB per photo = ~15–40 photos per GB

HEIC (High Efficiency Image Container) is Apple's default format since iOS 11 and uses roughly half the storage of JPEG at equivalent quality. If your iPhone is set to "Most Compatible" in Settings > Camera > Formats, it shoots JPEG and consumes about twice as much space.

How Much Storage Does Video Use?

Video dwarfs photos in storage consumption. Here's how much 1 GB of video gets you at common settings:

• 4K 30fps: ~2.5 minutes per GB
• 4K 60fps: ~1.5 minutes per GB
• 1080p 30fps: ~10 minutes per GB
• 4K ProRes (iPhone 15/16 Pro): ~1 GB per minute

If your camera roll is filling up fast, video clips are almost certainly the biggest culprit. See our 4K video storage guide for a full breakdown.

How Many Photos Can Each iPhone Model Hold?

Using the HEIC estimates above, here is roughly how many 48MP photos each storage tier holds:

• 128 GB iPhone: ~22,000 photos (accounting for OS overhead)
• 256 GB iPhone: ~45,000 photos
• 512 GB iPhone: ~90,000 photos
• 1 TB iPhone: ~180,000 photos

In practice, your phone also runs the OS, apps, and cached data, so available space for photos is roughly 10–20 GB less than the advertised storage. See How Many Photos Can an iPhone Hold? for model-by-model figures.

Tips for Getting More Photos Per Gigabyte

If you want to maximize how many photos fit on your iPhone, try these settings:

• Use HEIC format: Settings > Camera > Formats > High Efficiency (default on most iPhones)
• Enable Optimize iPhone Storage: Settings > Photos > Optimize iPhone Storage stores full-res in iCloud and keeps smaller previews locally
• Delete burst photos: A single burst contains 20–100 near-identical shots — keep only the best
• Review old videos: One video can equal hundreds of photos in file size

For help identifying and removing the biggest storage hogs quickly, Swype Photo Cleaner lets you swipe through photos one by one to keep or delete them in seconds.
