Have you ever stored an image from the internet and noticed it appeared with a .jfif suffix in place of the standard .jpg, you are not alone. JFIF — short for JPEG File Interchange Format — is a specification defining how JPEG images is saved.
Simply put, a JFIF image is a JPEG file. The .jfif suffix shows up primarily when saving images from certain browsers, particularly when the image comes lacking a defined file type header.
JFIF files started showing to regular users because some older browsers — especially older versions of Microsoft Edge — store JPEG images with the correct .jfif extension if the server does not specify the download name.
The solution is easy: either rename the extension from .jfif to .jpg, or run it through a conversion tool to produce a standard JPG file. Either way, the image data remains unchanged.
The easiest method is a here direct file rename. On Windows, activate showing file extensions in File Explorer, right-click the .jfif image, choose Rename and change the extension to .jpg.
