Every photo imported into Day One is converted to JPEG format and resized to a maximum resolution of 2100 x 2100 pixels. The aspect ratio is maintained. We resize photos for more efficient sync and storage. At this size the average photo is about 700KB which means you can store:
- Dropbox: 2,500+ photos using the free 2GB account
- iCloud: 6,000+ photos using the free 5GB account
- Day One Sync: Unlimited photos
Your actual amount may be lower depending on what other data you are storing in Dropbox or iCloud.
When you take a photo using Day One on your iPhone or iPad, by default the original, full-resolution image is saved to your Camera Roll. You can change this behavior in the Day One Settings panel.
