JFIF to JPG Comprehension and Changing This Format

If you have ever stored an photo from the online and discovered it appeared with a .jfif extension rather than the standard .jpg, you are not alone. JFIF — short for JPEG File Interchange Format — is a format that defines how JPEG photos is stored.

In practical terms, a JFIF image is a JPEG photo. The .jfif extension appears mainly after saving files from certain browsers, particularly if the image comes with no a proper content-type header.

This file extension appeared to most people as some older browsers — particularly older versions of Microsoft Edge — save JPEG images with the correct .jfif extension if the server fails to specify the file name.

The solution is easy: simply rename the extension from .jfif to .jpg, or use a online converter website to create a correctly named JPG image. Either way, the image data does not change.

The simplest approach is a direct file rename. On Windows, activate file extension display in File Explorer, click the .jfif image, select Rename and change the file extension to .jpg.
