To stop loading email pictures on an iPhone, open Settings, tap Apps, tap Mail, then tap Privacy Protection. Turn off Protect Mail Activity, then turn on Block All Remote Content, and Mail waits for you to ask before it downloads pictures stored on the internet.
These steps are for the built-in Mail app on iOS 27, and the same path works on iOS 26 and iOS 18. iOS 15 through iOS 17 skip the Apps step, older iPhones use a switch called Load Remote Images, and the Gmail and Outlook apps have their own settings. Each one is covered separately below.
What a Remote Image Is
Pictures arrive in email in two ways. An attached picture is sent as part of the message itself. A remote image is not in the message at all. The email only contains a web address, and your iPhone downloads the picture from that address when it shows the message. Store newsletters and marketing emails are built almost entirely from remote images.
Remote images matter for two reasons. Downloading them uses data, which counts against your plan when you are on a cellular connection. They can also tell the sender about you. Apple says that remote content can let a sender learn when you view a message, along with your IP address, which is the number that identifies your internet connection.
For a sender you never want to hear from again, you can also block the email sender on your iPhone.
Before You Change the Setting
Since iOS 15, the picture setting has been tied to a feature called Mail Privacy Protection. Its main switch is Protect Mail Activity. Apple’s Mail Privacy Protection privacy overview explains that when this switch is on, Mail downloads remote content in the background, whether or not you open the message, and routes it through two separate relays so the sender does not see your IP address.
That is good for privacy, but it means the pictures are still downloaded. To stop the downloads, you have to turn Protect Mail Activity off first. You are trading one kind of protection for another, so leave Hide IP Address turned on when the option appears. Hide IP Address keeps masking your IP address even when Protect Mail Activity is off.
How to Stop Loading Email Pictures in the Mail App
Apple’s guide to Mail Privacy Protection on iPhone covers this menu. On iOS 18 and later, including iOS 26 and iOS 27, Mail is inside the Apps section of Settings.
- Open the Settings app.
- Scroll to the bottom and tap Apps, then tap Mail. On iOS 15, 16, and 17, there is no Apps section. Scroll down the main Settings list and tap Mail instead.
- Tap Privacy Protection. It is in the Messages group of settings.
- Turn off Protect Mail Activity. Two more switches should appear below it: Hide IP Address and Block All Remote Content.
- Leave Hide IP Address turned on.
- Turn on Block All Remote Content. The switch turns green.
With Block All Remote Content on, Mail shows a banner when a message has remote content and waits for you to load it. The setting covers every account in the Mail app, and the iPad uses the same Settings > Apps > Mail > Privacy Protection path. On a Mac, the matching options are in Mail under Mail > Settings > Privacy.
How to Stop Loading Email Pictures on Older iPhones
Mail Privacy Protection arrived with iOS 15. Earlier versions use a single switch called Load Remote Images, and its location changed over the years.
- iOS 10 through iOS 14: open Settings, tap Mail, then turn off Load Remote Images in the Messages section.
- iOS 8 and iOS 9: open Settings, tap Mail, Contacts, Calendars, then turn off Load Remote Images.
The switch is off when it is no longer shaded green.
How to Check That It Worked and See Pictures When You Want Them
Open the Mail app and tap a newsletter or store email. The text should appear with empty spaces where the pictures would be, and a banner at the top should say the message contains remote content. Tap Load Content in that banner to download the pictures for that one message. Older versions label the button Load All Images.
Loading pictures in one email does not change the setting. The next email still opens without them.
To undo the change, go back to the Privacy Protection menu and turn Protect Mail Activity back on. On an older iPhone, turn Load Remote Images back on.
Gmail and Outlook Apps on iPhone
The Settings app only controls Apple’s Mail app. If you read email in a different app, change the setting inside that app.
For the Gmail app, Google’s instructions to turn images on or off in Gmail are: open the Gmail app, tap Menu at the top left, tap Settings, then under Inbox tap Email preferences, Images, and Ask before displaying external images. To see pictures in a message afterward, tap Display images. On a computer, you can also get Gmail to ask before displaying external images.
Outlook for iOS has a setting called Block external images. That setting does not block images that are embedded in the email as attachments. Look for it in the Outlook app’s settings for your email account.
Outlook also lets senders ask for a read receipt, and you can stop Outlook from sending read receipts in its settings.
Troubleshooting
- You do not see Block All Remote Content. It stays hidden while Protect Mail Activity is on. Turn that switch off and the extra options should appear.
- You cannot find Mail in Settings. On iOS 18 and later, tap Apps at the bottom of Settings first. You can also type Mail into the search field at the top of Settings.
- Pictures still appear in some emails. Pictures that the sender attached are part of the message, so this setting does not hide them. It only affects pictures stored on the internet.
- Pictures still load in every email. Check which app you are reading mail in. Gmail, Outlook, and other apps ignore the Mail setting.
- You see “Unable to load remote content privately.” This can happen with Protect Mail Activity on, for example when you use a VPN. Tapping Load Content loads the pictures without Mail Privacy Protection. More detail is on Apple’s If you see Unable to load remote content privately page.
- Pictures are missing and you want them back. For help, read why iPhone Mail isn’t showing any pictures.
Frequently Asked Questions
Does blocking remote images save cellular data?
It can. With remote content blocked, Mail does not download internet-hosted pictures until you ask for them, so image-heavy newsletters use less data. The text of each email and any attachments you open still use data.
Is Protect Mail Activity or Block All Remote Content better?
They do different jobs. Protect Mail Activity still downloads pictures, but privately and in the background, so emails look complete and the sender learns less about you. Block All Remote Content downloads nothing until you tap to load it. Choose the first if you mainly care about privacy and convenience, and the second if you want to limit downloads.
Will senders know I opened an email if pictures are blocked?
Tracking that depends on remote content cannot run while that content is not downloaded. Once you tap to load the pictures in a message, the sender may be able to tell that it was opened.
Does blocking pictures protect me from phishing emails?
No. It stops tracking pictures, but links in the message still work. If an email asks you to update your password, do not use its link. Change the password on your email provider’s website or app instead, then update the email password on your iPhone.
Does it change photos I send or receive as attachments?
No. The setting only controls remote content. Photos that someone attaches to an email, and photos that you attach, are handled as attachments.
Next Steps
If your goal is to use less of your data plan, email pictures are only one piece. Several other settings can reduce cellular data usage on an iPhone, and you can also turn off cellular data for a single app such as YouTube.
