Why convert JFIF to JPG?
JFIF is really just a JPEG saved with a different extension, which is why Windows sometimes produces it and other programs then refuse to open it. This gives you a normal .jpg that behaves as expected everywhere.

JFIF is already a JPG
JFIF (JPEG File Interchange Format) is the standard way JPEG images have been stored since 1992. A .jfif file is a JPG with a different extension — the image data inside is the same. The extension usually appears when you save an image from a website in Chrome or Edge on Windows, because a Windows registry setting maps the image type to .jfif.
Some upload forms, editors and phones only accept files that literally end in .jpg, so they reject a perfectly good .jfif file.
Two ways to fix it
You can simply rename the file from photo.jfif to photo.jpg — it will open normally because the content is identical. Converting with Localvert does the same job for many files at once, and also removes hidden metadata from the image.
To stop Windows saving new images as .jfif, the fix is a registry change (the "Content Type" value under HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/jpeg should have the extension .jpg). Only do this if you're comfortable editing the registry.
Is it safe?
Yes. This conversion runs entirely inside your browser, and your JFIF file is never sent to a server. Metadata such as location is also removed automatically.

Frequently asked questions
Does converting lose quality?
Converting re-encodes the image, so choose the High preset to keep it visually identical. If you want zero change, renaming the extension is enough.
Why does my browser save images as .jfif?
It's a Windows setting rather than the website. Other people on other computers may get .jpg from the same image.
Is .jpeg different from .jpg?
No. .jpg, .jpeg, .jpe and .jfif are all the same format; .jpg became common because old versions of Windows only allowed three-letter extensions.
Is it really free?
Yes. Converting JFIF to JPG is free with no sign-up and no watermark. The free plan handles several files per batch; an optional premium licence removes ads and raises the limits.
Are my files uploaded anywhere?
No. Your JFIF files are read and converted by your browser on your own device. You can confirm it by opening your browser's developer tools and watching the Network tab while you convert: no file upload ever appears.
