Question 1

What is a JFIF file?

Accepted Answer

JFIF stands for JPEG File Interchange Format. It is a specific implementation of the JPEG standard — essentially the same as JPG but with a standardized file structure for cross-platform interchange. JFIF files use the .jfif extension and are technically identical to .jpg files in terms of image data.

Question 2

How do I convert JFIF to JPG?

Accepted Answer

Upload your .jfif file using the converter above and click "Convert to JPG". The output is a standard .jpg file that opens in any app. Since JFIF is essentially JPEG, this conversion is a lossless extension rename — no image quality is lost.

Question 3

Why does my browser save images as JFIF instead of JPG?

Accepted Answer

Some browsers (particularly older versions of Edge and Internet Explorer) save downloaded JPEG images with the .jfif extension instead of .jpg. This happens because the JFIF header format is detected and the browser uses the corresponding extension. Converting to .jpg makes the file open in all applications.

Question 4

Can I open a JFIF file without converting it?

Accepted Answer

Many modern apps can open JFIF files directly. However, some apps (especially older ones or specialized software) only recognize .jpg or .jpeg extensions. If your app doesn't open JFIF, converting with our tool produces a .jpg that works everywhere.

Question 5

Is JFIF the same as JPEG?

Accepted Answer

Yes, essentially. JFIF is a specific subset of the JPEG standard that defines how JPEG data should be stored for interchange between applications. All JFIF files are JPEG files, and most JPEG files conform to the JFIF standard. The only practical difference is the file extension.
