The only way to prevent that is to make sure the image meets the recommended dimensions before you upload it. There is currently no way to prevent Facebook from cropping large profile pictures.
How do I make my Facebook profile picture not zoom in?
Facebook Profile Picture Resizer
When you upload a photo, Facebook shows you a thumbnail of the image. Roll the mouse pointer over the thumbnail and you’ll see a paintbrush icon with the caption, “Edit Photo.” Click the icon to bring up the Photo Editor. Slide the slider below your photo to enlarge or reduce it.
How do I get rid of the zoom profile picture?
On the page that opens, find the “Account Profile” bar and tap the downwards facing arrow next to it. From the menu that appears, choose “Profile.” Select the “Delete” option provided beneath the thumbnail of your current profile picture.
How do I make my whole profile picture fit on Facebook?
Click the “Scale to fit” check box to display the entire profile picture in the thumbnail. When you select this option, Facebook resizes the image to fit in the box.
Why does my profile picture zoom in on Facebook?
If your face is too large in the photograph to fit in the thumbnail square, check the box next to “Scale to fit.” Facebook reduces the size of your photo in the thumbnail square so that the entire photo fits.
How do I not Crop my profile picture on Facebook?
To skip cropping on mobile, go to m.facebook.com using mobile browser, then upload the image as a post on your timeline and use the “Make Profile Picture” option below the post, which will make the image as your Profile Picture without cropping.
