How To Fix Problems Viewing JFIF Files

Every now and then I like to save pictures, memes, and whatnot off the Internet. Usually, they are a standard format like JPG or PNG, and sometimes GIF. But then an odd thing came about– pictures ending with the extension JFIF. I would not have noticed except that my picture viewer of choice, XnView, doesn’t seem to handle the format very well. But the thing here, according to the documentation that came with XnView, it should support the JFIF format. A minor glitch in my system I suppose.

I have to use Windows Photos to open them but there is another option– renaming the extension. Since it seems to be a variation of JPG, renaming the extension from JFIF to JPG does the job.

To rename extensions, you’ll need to see them first so type in File Explorer Options in search, then click on it.


Then click on the View tab and scroll down to Hide extensions for known file types.


Uncheck the box. Then Apply and OK. Now you should see the extensions on your files. Right-click on a file to rename it or highlight it and press F2 and rename the JFIF file extension to JPG. Click on Yes in the warning prompt box that pops up afterward.
