How to blur, pixelate or black out images on iPhone?

The photos and pictures may contain sensitive information, such as name, address, phone number, etc. When you post images, photos, screenshots on Facebook, Twitter and other social networks, you may need to hide the private information. You don’t need a third-party app on iPhone to blur, black out or pixelate images if you want to hide a certain area of the image due to privacy or security. Some messaging apps have already support photo editing before sending them, such as WhatsApp, WeChat. In fact, this ability has also been added to iPhone iPad since iOS 10. It is known as the built-in Markup image editor for iOS. It does not come as a separate app though. You can find and access it from Photos, Mail, Messages and Notes app on iPhone or iPad.
