How Many Photos Can 1 TB Hold?
This page answers how many photos a terabyte holds and lets you recalculate with your own camera's average file size.
Quick answer: At the common 8 MB per photo (24 MP JPEG), 1 TB holds about 125,000 photos. Phone HEIC photos at 1.8 MB reach roughly 555,000; 45 MP RAW files at 55 MB drop it to about 18,000.

| Capacity | How many photos |
|---|---|
| 32 GB | 17,777 |
| 64 GB | 35,555 |
| 128 GB | 71,111 |
| 256 GB | 142,222 |
| 512 GB | 284,444 |
| 1 TB | 555,555 |
| 2 TB | 1,111,111 |
| 4 TB | 2,222,222 |
| 1 TB decimal | 1,000 GB = 1,000,000,000,000 bytes |
|---|---|
| Phone (HEIC ~1.8 MB) | ≈ 555,000 photos |
| 12 MP JPEG (~4 MB) | ≈ 250,000 photos |
| 24 MP JPEG (~8 MB) | ≈ 125,000 photos |
| 45 MP RAW (~55 MB) | ≈ 18,000 photos |
| In Windows | The same drive reports 931 GiB, so counts are ~7% lower |
Why the answer varies by 30×
A photo's size is decided by resolution, format and how much detail the scene contains: a phone HEIC at 12 MP lands near 1.8 MB, a camera JPEG at the same resolution near 4 MB, double the resolution near 8 MB, and a 45 MP RAW file around 55 MB. Compression differs too — a high-ISO concert shot compresses worse than a clean landscape at identical settings.
Where a 1 TB photo library actually lands
Most people who ask this question are consolidating a decade of phone photos plus a camera library. A realistic mix — 60,000 phone HEICs (108 GB), 20,000 camera JPEGs (160 GB) and 3,000 RAW keepers (165 GB) — totals about 433 GB, so 1 TB holds the whole archive with room for several more years at the same pace.
Budgeting for backups, not just storage
A photo library should exist in three places: the working drive, a local backup and an off-site copy. That triples the raw requirement — a 400 GB library wants a 1 TB working drive, a 1 TB backup drive and a matching cloud tier. Cloud services count decimal GB, so a 1 TB plan stores the 400 GB library comfortably, while “1 TB free” in a binary display is 931 GiB.

- Deciding whether a 1 TB drive can absorb an existing photo library.
- Comparing cloud plans against a real photo count.
- Explaining the storage difference between phone and camera libraries.
- Planning how many photos a wedding or event archive will add.
- Estimating how long a 1 TB drive lasts at your shooting rate.
