Many users have stored an image from the web and discovered it saved with a .jfif file extension instead of the expected .jpg, this is common. JFIF — which stands for JPEG File Interchange Format — is a standard that defines how JPEG image data is encoded.
Essentially, a JFIF photo is a JPEG file. The .jfif suffix appears primarily when saving files from specific browsers, mainly if the image is delivered without a specific MIME type.
JFIF files appeared to everyday users because some older browsers — especially legacy versions of Microsoft Edge — download JPEG files with the correct .jfif extension when websites fails to specify the filename.
The fix is simple: just rename the file extension from .jfif to .jpg, or run it through a conversion tool to create a properly labelled JPG image. In both cases, the photo content remains unchanged.
The easiest method is a direct file rename. For Windows users, enable showing file extensions in File Explorer, click the .jfif file, select Rename and update the extension to .jpg.
