iCloud: Photo Stream limits
While there is no limit to the number of photos you can upload to Photo Stream over time, iCloud limits the number of photos that can be uploaded within a given hour, day, or month to prevent unintended or excessive use.
Photo Stream upload limits
The Photo Stream limits below are established based on anticipated upload patterns. Currently, Photo Stream upload limits are as follows:
- Uploads to My Photo Stream per hour: 1,000 photos
- Uploads to My Photo Stream per day: 10,000 photos
- Uploads to My Photo Stream per month: 25,000 photos
If you exceed one of these limits, your uploads to Photo Stream will be paused temporarily and you may see a notification message on your device. Your uploads will resume automatically once you no longer exceed one of the limits (such as the following hour or day).
Shared Photo Stream limits
The current Shared Photo Stream hourly and daily limits are as follows:
- Maximum number of photos to share per hour: 1,000
- Maximum number of photos to share per day: 10,000
These sharing limits are separate from the upload limits above. For example, in the same day you could upload 10,000 photos to My Photo Stream and then share those 10,000 photos, or 10,000 other photos.
Some additional limits for Shared Photo Stream usage:
- Maximum shared streams an owner can share: 100
- Maximum shared streams a user can subscribe to: 100
- Maximum subscribers per shared stream: 100 (the number of subscribers on each shared stream)
- Maximum number of photos per shared stream: 1,000
- Maximum number of comments per shared stream photo: 200 (a comment can be either a like or a text entry)
- Maximum characters per comment: 200
- Maximum number of invites a shared stream owner may send per day: 200
- There is no limit to the amount of photos you can upload to Photo Stream over longer periods (such as several months or years). Photos uploaded to Photo Stream are not counted against your iCloud Storage.
- The following image file types are supported for Photo Stream: JPEG, TIFF, PNG, and RAW.
- When importing photos to an iPad using the Camera Connection Kit, photos are stored directly to Camera Roll. Thus, if Photo Stream is enabled and you are connected to a wireless network, you could potentially reach any of the limits listed above. To avoid this, disable Photo Stream when importing photos to iPad when using the Camera Connection Kit.
- When importing large numbers of photos to either iPhoto or Aperture, you could potentially reach any of the limits listed above if you have selected Automatic Upload in the Photo Stream preferences. Note that both iPhoto and Aperture will pause uploading to Photo Stream once the maximum has been reached. Uploading will automatically restart at the next hour, day, or month, depending on which limit was reached.
