The Pixel 9 starts at 128 GB with options up to 1 TB (Pro), uses JPEG by default (3-5 MB avg), and offers 15 GB free Google storage. iPhone photos are ~40% smaller per shot, but Pixel gives you 3x more free cloud storage.

Storage Tiers
| Model | Storage Options | Starting Price |
|---|---|---|
| iPhone 17 | 256 GB, 512 GB | $799 |
| iPhone 17 Pro | 256 GB, 512 GB, 1 TB | $1,099 |
| iPhone 17 Pro Max | 256 GB, 512 GB, 1 TB, 2 TB | $1,199 |

| Pixel 9 Pro XL | 128 GB, 256 GB, 512 GB, 1 TB | $1,099 |
The iPhone 17 has a significant edge at the base level — 256 GB vs. 128 GB at the same $799 price point. At the top end, the iPhone 17 Pro Max offers 2 TB, which no Pixel model matches.
Free Cloud Storage
This is where Pixel has a clear advantage. Google provides 15 GB free across Google Photos, Gmail, and Google Drive. Apple provides just 5 GB free for iCloud, which fills up almost immediately when photo backup is enabled.
| Plan | iCloud (iPhone) | Google One (Pixel) |
|---|---|---|
| Free | 5 GB | 15 GB |
| $0.99/mo | 50 GB | -- |
| $1.99/mo | -- | 100 GB |
| $2.99/mo | 200 GB | 200 GB |
| $9.99/mo | 2 TB | 2 TB |
| $29.99/mo | 6 TB | -- |
| $59.99/mo | 12 TB | -- |
Note: Google ended unlimited free photo storage in June 2021. Pixel 9 photos count against your 15 GB quota just like any other device. However, Google Photos offers a "Storage Saver" mode that slightly compresses photos to reduce space usage.
Photo File Sizes
iPhone uses HEIC by default, which is roughly 40-50% smaller than JPEG at equivalent quality. Pixel defaults to JPEG, though it can be switched to HEIC in settings.
- iPhone 17 standard photo: 2-3 MB (HEIC, 48MP binned to 24MP)
- Pixel 9 standard photo: 3-5 MB (JPEG, 50MP binned to 12.5MP)
- iPhone 17 Pro ProRAW: 50-75 MB per photo
- Pixel 9 Pro RAW: 12-25 MB per photo
For everyday photography, iPhones store roughly 40-50% more photos per GB. In RAW mode, Pixel files are actually smaller because of the lower-resolution sensor output, but RAW is a niche use case for most users.
Video Storage and Codecs
Both phones shoot 4K video, but codec choices differ significantly:
- iPhone 17: HEVC (H.265) by default — ~60 MB/min for 4K 30fps. ProRes available on Pro models (~1.7 GB/min for 4K 30fps ProRes LT).
- Pixel 9: H.264 by default — ~120 MB/min for 4K 30fps. HEVC available in settings. No ProRes equivalent.
iPhone's default HEVC codec produces video files roughly half the size of Pixel's default H.264. For heavy video shooters, this means significantly more recording time per GB on iPhone. The iPhone 17 Pro's Apple Log and ProRes options are also storage-intensive but offer professional-grade footage.
