If you have ever downloaded an photo from the web and found it downloaded with a .jfif extension in place of the standard .jpg, this happens often. JFIF — short for JPEG File Interchange Format — is a specification that defines the way JPEG photos is saved.
Simply put, a JFIF file is a JPEG photo. The .jfif file type shows up primarily while saving photos from some web browsers, particularly when files are is delivered without a specific MIME type.
This file extension became visible to most people since some browsers — mainly legacy versions of Microsoft Edge — download JPEG photos with the proper .jfif file extension when the server omits the file name.
The fix is simple: simply rename the file extension from .jfif to .jpg, or process it with a converter tool to generate a properly labelled JPG photo. Either way, the photo content remains unchanged.
The quickest fix is a simple rename. For Windows users, turn on file extension visibility in File Explorer, right-click the .jfif image, select Rename and update the extension to .jpg.
