If you have ever downloaded an picture from the online and noticed it appeared with a .jfif file extension rather than the expected .jpg, you are not alone. JFIF — which stands for JPEG File Interchange Format — is a format defining how JPEG image data is stored.
Essentially, a JFIF photo is a JPEG file. The .jfif suffix appears mostly when saving images from certain browsers, especially if the image was served with no a defined MIME type.
The .jfif extension started showing to everyday users as some browsers — mainly legacy versions of Microsoft Edge — download JPEG images with the correct .jfif file extension when the server fails to specify the download name.
The fix is simple: just rename the file check here extension from .jfif to .jpg, or use a conversion tool to produce a correctly named JPG photo. In both cases, the picture quality does not change.
The easiest method is a file extension change. On Windows, turn on file extension visibility in File Explorer, right-click the .jfif image, select Rename and change the extension to .jpg.
