I wrote before about my problems with opening .jfif files with XnView, my picture viewer of choice. It still has its fits when it comes to opening .jfif and .jpeg files.

Normally I just rename the .jfif extension to .jpg since it is a .jpg file. I was searching for a solution to a commentator’s problem with ending up with black pictures while converting from HEIC to JPG. Read here:
Apparently, this .jfif extension came about because of a Microsoft update. Who would have guessed – a Microsoft update screwing up the system. 🙂
If I saved a picture on Twitter, for example, it usually always defaulted to the .jfif extension. So I had to remember to change it while downloading or change it after the download; both ways were a nuisance. But I found a Registry tweak that fixes this problem.
Standard warnings, be careful editing the registry. One wrong snip … I’ll let your imagination fill in the rest. 🙂
In the search bar, type regedit
In the editor, in the Address bar, copy and paste (or type) the following and hit enter:
Double click on the word Extension in the right-hand pane. In the Value data box Where it says .jfif, erase that and type in .jpg
Click on OK and close the editor.
It should take effect right away, no restart is required. If you don’t want to edit the registry this way, then you can download a ready-made Registry file here:
Right-click on it. Then Save as… and Double-click on the downloaded file. Accept all prompts.
Adding information warning … click Yes
Keys added successfully … click OK
Allow any other security prompts.
