Is JFIF actually a different image format from JPEG?

Not meaningfully — JFIF is essentially the same JPEG image data, just with a different file extension and minor header differences.

Will converting JFIF to JPEG change image quality?

No, since the underlying image data is nearly identical, there's no meaningful quality change.

Why did my downloaded image end up with a .jfif extension?

Some browsers save images with that extension automatically, even though the content is standard JPEG data.

Will renaming the file instead of converting it work just as well?

In many cases yes, but running it through a proper conversion ensures the file is fully normalized and compatible.

What is JFIF ?

JFIF, the JPEG File Interchange Format, is how JPEG-compressed pictures are stored in a file: the compressed image data plus a short header giving the version, resolution and an optional thumbnail. A .jfif file is a JPEG — the same bytes most software calls .jpg — under an older extension.

Why Convert JFIF to JPEG file?

JFIF (JPEG File Interchange Format) is, for practical purposes, the same underlying image data as a standard JPEG — the difference is mostly in file extension and a few header details. Some browsers and apps save downloaded images with a .jfif extension, which then confuses software that expects the more common .jpg or .jpeg.

Converting to JPEG simply relabels and normalizes the file so it opens without hesitation in any photo viewer, editor, or upload form that checks file extensions. There's no meaningful quality change involved, since the underlying image data is nearly identical between the two.
