JFIF to JPG Converter

JFIF files are ordinary JPEG images with an unusual file extension – yet many websites and programs refuse them. Convert any number of .jfif files to .jpg at once, or stop Windows from creating them in the first place.

Choose JFIF files – or drop or paste them hereAs many files as you like · converted in your browser, nothing is uploaded

Photos are turned the right way up, and metadata such as the GPS location is not copied into the converted files.

    How to convert JFIF to JPG

    1. Choose your .jfif files or drop them on the page.
    2. Keep the default quality of 90 % or adjust it.
    3. Download the .jpg files one by one, or all at once as a ZIP.

    What is a JFIF file?

    JFIF (JPEG File Interchange Format) is the standard way JPEG images are stored – almost every .jpg file is a JFIF file inside. A .jfif extension therefore does not mean a different format, only a different name. For a single file, renaming it from .jfif to .jpg is enough. The converter is quicker for many files: it saves each image again as JPG (at 90 % quality by default), turns photos the right way up and leaves out metadata such as the GPS location.

    Why Windows saves .jfif files – and how to stop it

    When you save a JPEG image from the web, Windows picks the file extension from a registry entry. Some programs change this entry to .jfif, and from then on browsers save JPEGs as .jfif. To change it back:

    1. Press Windows + R, type regedit and press Enter.
    2. Open HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/jpeg.
    3. Double-click Extension and change the value from .jfif to .jpg.
    4. Restart your browser.

    Editing the registry needs administrator rights. If you prefer not to, simply rename or convert the files.

    Frequently asked questions

    Is JFIF the same as JPG?

    Yes. Both contain JPEG image data; only the file extension differs.

    Can I just rename a .jfif file to .jpg?

    Yes – the file then opens everywhere, without any change to the image. The converter is handy when you have many files or want to remove metadata at the same time.

    Why do some websites reject JFIF files?

    Many upload forms only check the file extension and accept .jpg, .jpeg and .png, but not .jfif – even though the image data is the same.

    Are my files uploaded?

    No. The conversion runs in your browser, and your images never leave your device.
