Frequently asked

What is a JFIF file? +

JFIF (JPEG File Interchange Format) is the standard container most JPEGs use. The pixels are the same as a regular .jpg. Only the filename extension is different.

Will the result look identical? +

Yes. The original JPEG pixels are decoded once and saved losslessly to PNG, so nothing degrades further.
