High-resolution versions of your Instagram photos are saved to your device after you upload the photo to Instagram. This means that you are the only one with access to high-resolution versions of your photos.

We will always save images in the highest resolution size possible. The maximum resolution on both Android and iOS is 2048x2048, but your device’s resolution capabilities may be lower than that.

On Android devices, image resolution capabilities vary widely by device.

For iOS devices, the resolutions of photos taken with the Instagram camera (not the Camera application) and saved to your device are:

• 2048x2048 on the iPhone 4s
• 1936x1936 on the iPhone 4
• 1536x1536 on the iPhone 3GS

Please note that photos imported from your iOS device (not taken with the Instagram camera) and then uploaded to Instagram will save at a much lower resolution (612x612). Apple has recently updated their API to allow high resolution importing to applications, and while this feature will be available in the future, we have no estimate for its release.

You must turn on your save photo settings to make sure filtered photos save to your phone.
