Deleting the photos from your iPhone can free up considerable space, especially if you have hundreds or even thousands of pictures on your device. Unlike iOS 6, iOS 7 doesn't include a mass-purge feature for photos, but you can make the task go more quickly by deleting the photos in groups rather than one-by-one. To really speed things up, connect your iPhone to your Windows or Mac computer, and then delete all the photos at once.

Delete From iPhone

Step 1

Open the "Photos" app, and then tap "Photos" at the bottom of the screen.

Step 2

Change the view to "Moments" if you see "Years" or "Collections" at the top of the screen. To change the view, tap one of the thumbnail groups on the screen until the screen header displays "Moments."

Step 3

Tap "Select" at the top of the screen to enter selection mode. The iPhone groups the photos based on the date and locations of the photos.

Step 4

Select all of the groups by tapping the word "Select" at the top of each group. Scroll down and continue selecting groups until you select them all. This may take a while if you have a lot of pictures to delete.

Step 5

Click the trash can icon to delete the photos.

Delete Using Windows

Step 1

Turn on the iPhone, and then connect it to a USB port on your Windows computer.

Step 2

Press "Windows-E" to open the Windows file browser.

Step 3

Double-click the listing for your iPhone in the left pane, and then navigate to the "\Internal Storage\DCIM\100APPLE" folder. Delete everything in the folder.

Step 4

Right-click the iPhone icon and select "Eject" before disconnecting the device from your computer.

Delete Using Mac OS X

Step 1

Turn on the iPhone, and then connect it to the Mac's USB port. Launch "Image Capture" from the "Applications" folder on the computer.

Step 2

Select your iPhone as the device in the left pane, and then press "Command-A" to select all the photos on the screen.

Step 3

Click the red button at the bottom of the screen to delete the pictures from your iPhone. Click "Delete" to confirm the action.
