JFIF to JPG ConverterSaved a picture from the web and got a .jfif file instead of a .jpg? Many upload forms, apps and editors refuse the .jfif extension even though the image inside is a normal JPEG. Convert it here and you get a standard .jpg file that is accepted everywhere.
JFIF vs JPG: what changes
JFIF (JPEG File Interchange Format) is simply the standard way JPEG images are stored, so a .jfif file and a .jpg file contain the same kind of picture. The only practical difference is the name: software and websites check the extension, and many do not recognise .jfif. Converting gives the image the .jpg name and a clean, standard file.
When to convert JFIF to JPG
Use it when a job portal, exam form, marketplace or social app says the file type is not allowed, when Photoshop or a phone app will not open the file, or when you are tidying a folder of images saved from Chrome or Edge on Windows.
Before you convert
The picture is re-saved as a high-quality JPG, which can change it very slightly. If you want a byte-for-byte identical file, you can also rename the extension from .jfif to .jpg yourself in File Explorer (turn on ‘File name extensions’ under View). Both methods produce a valid JPG.
Tips for converting JFIF to JPG
To stop getting .jfif files, type the file name with .jpg at the end when you save an image from your browser. For a whole folder, convert the files one after another here.
Convert JFIF to JPG on any device
On Windows, open File Explorer, find the .jfif file (often in Downloads) and drag it onto the upload box. On phones, tap the box and choose the file from Files or Downloads.
Common problems and fixes
Why do my downloads save as .jfif?
Windows sometimes labels JPEG images as JFIF when you save them from a browser. It is a JPEG inside with a different extension.
A form rejects my .jfif photo
Upload forms often check the extension and only allow .jpg. The converted file has the .jpg ending they expect.
Can I just rename the file?
Often yes, because the content is already JPEG. Converting is the safe option when renaming does not work or you cannot change extensions on your device.

Frequently asked questions
Why does Windows save images as .jfif?
On some Windows computers a registry setting maps JPEG images to the .jfif extension, so Chrome and Edge suggest .jfif when you save a picture. The image is a JPEG either way.
Can I stop Windows saving JFIF files?
Yes. When saving, type the name with .jpg at the end, or change the Extension value for image/jpeg in the Windows registry to .jpg. Converting existing files here is the quicker option for most people.
Is converting JFIF to JPG safe for quality?
Yes. The image is saved at high JPG quality, and the change is not visible in normal use.
