# iPhone Photo Size Estimator

Estimate the total storage a batch of iPhone photos will take based on format (HEIC, JPEG, or ProRAW) and count, and see what share of your iPhone it will consume.

## 1. Choose Your Photo Format

## 2. How Many Photos?

## 3. Your iPhone Storage (GB)

## Your Photo Storage Estimate

Shooting in HEIC instead of JPEG cuts your photo storage by roughly 25%. Shooting ProRAW is visually stunning but 8–25x larger. Use [Swype Photo Cleaner](https://apps.apple.com/us/app/clean-phone-storage/id6752439949) to quickly remove duplicates and blurry shots from your camera roll.

## Frequently Asked Questions

### How accurate is this photo size estimator?

The averages used (HEIC 3 MB, JPEG 4 MB, ProRAW 12MP 25 MB, ProRAW 48MP 75 MB) reflect typical iPhone captures of everyday scenes. Actual file sizes vary by subject complexity: a detailed landscape with lots of color can be 30–50% larger than a flat wall. Totals are accurate within about 15% for most real-world libraries.

### Why is ProRAW 48MP so much larger than HEIC?

ProRAW files preserve raw sensor data with Apple’s computational photography metadata layered on top, so they can be edited like a traditional RAW file. At 48MP on an iPhone 14 Pro or later, each file is roughly 75 MB — about 25 times bigger than a HEIC. Only shoot ProRAW for images you plan to edit seriously.

### Does the percentage reflect usable storage?

No — the percentage compares your photos to the total advertised iPhone storage (e.g., 128 GB). In practice, iOS and pre-installed apps take 10–15 GB, and iPhones report storage in base-10 gigabytes. For a more realistic breakdown that subtracts iOS and apps, use our [iPhone Storage Calculator](https://dblabsapps.com/tools/iphone-storage-calculator/).

### How can I reduce the storage my photos use?

Switch to HEIC in Settings > Camera > Formats > High Efficiency, only shoot ProRAW when you need it, delete blurry duplicates and screenshots regularly, and consider enabling iCloud Photos with “Optimize iPhone Storage” turned on.
