Facebook profiles have changed little since the social network launched Timeline in 2011, until now. Last week, Facebook announced a redesign of mobile profile pages that introduce looping profile videos, temporary profile pictures, new privacy controls and other design changes.\nProfile pages, though dwarfed by the popularity of news feed, still receive more than 4 billion views every day, the social network says. Coupled with the rise of video on the social network, Facebook says it was time for an update.\n\u201cThe world has changed since we first introduced profiles in 2004. On news feed and profiles, we\u2019re seeing people create and view more videos than ever before,\u201dit said in a blog post. \u201cWe believe these improvements to profile will give people more ways to connect and share with each other, and express themselves in meaningful ways.\u201d\nFacebook is launching these new features first in the U.K. and California, with more locations to follow. Here\u2019s what you need to know about what\u2019s new.\n1. Redesigned profile page\nFacebook is making your profile picture\u2014or looping profile picture\u2014bigger, and moving it front-and-center at the top of your profile, in place of its traditional left alignment.\nIt\u2019s also customizing which friends are highlighted based on who\u2019s viewing your profile: \u201cPeople love seeing photos and mutual friends when viewing the profiles of friends or someone they\u2019ve just met, so those are easier to see now on profile,\u201dFacebook says. These sections have moved to the top of the page.\nAlso visible at the top of profile pages are your work, location and education information. Moving this information to the top might persuade users to keep these details updated\u2014a win for Facebook advertisers, which can use it to better target ads.\n2. Looping profile videos \nThe most significant change Facebook announced is the ability to add short GIF-like videos in place of your profile picture. This feature is rolling out slowly, and only to iPhone users first.\nTo find the feature, open the Facebook app on your iPhone then tap the More button on the bottom-right of the screen. Tap your name to access your profile, then tap your current profile picture. In the menu that appears, you\u2019ll either see \u201cComing Soon: Profile Videos\u201d or \u201cTake a New Profile Video.\u201d If you have the feature, tap it to record a short video or upload one from your Camera Roll.\n3. Temporary profile pictures\nAlso new is the capability to set a particular profile picture for a period of time that reverts back to your previous one after time has expired. Facebook says this feature stemmed from its Celebrate Pride filter, which more than 26 million people used.\n\nUsers might choose this option if they want to support a sports team leading up to game time or commemorate a milestone like a birthday, Facebook says. When you receive this feature, you\u2019ll find editing tools in the profile picture uploader that lets you crop and add text and stickers to your new profile picture. You\u2019ll also have the option to set this picture as your default for a period of time.\n4. New profile privacy controls\nThe \u201cView As\u201dfeature, which you can find on the desktop version of your profile page, has traditionally been the only way to see what others see when they look at your profile. Facebook is introducing a new customizable space at the top of your profile that pulls information from your \u201cAbout Me\u201dpage and includes inline privacy settings.\n\nInformation you have set to public will appear automatically in this section, which you can change by editing the new, inline privacy settings. You can also craft a 100-character bio that supports emojis, which will appear below your profile picture. Finally, a new photo carousel will highlight up to five photos you choose to showcase at the top. This space is visible to anyone who visits your profile, but you control the information that appears there.
