Have you ever stored an picture from the online and noticed it appeared with a .jfif suffix in place of the usual .jpg, this is common. JFIF — short for JPEG File Interchange Format — is a specification defining how JPEG image data is encoded.
Essentially, a JFIF photo is a JPEG file. The .jfif suffix appears mostly while saving files from some web browsers, particularly if the image comes without a defined file type header.
This file extension appeared to convert jfif to jpg regular users since some older browsers — particularly older versions of Microsoft Edge — store JPEG files with the correct .jfif file extension when the server fails to specify the filename.
The fix is simple: simply rename the extension from .jfif to .jpg, or use a converter tool to generate a properly labelled JPG file. In each case, the photo content remains unchanged.
The simplest approach is a file extension change. On Windows, enable file extension display in File Explorer, right-click the .jfif image, select Rename and modify the file extension to .jpg.
