About JFIF to JPG
If an image you saved from the web ended up with a .jfif extension, you're not alone. JFIF is the JPEG File Interchange Format, so these files are already JPEG images inside; Windows simply labels some of them with the older extension. Many upload forms and apps don't recognise .jfif, though. This converter re-saves each file as a .jpg, with optional resizing, a quality setting and the choice to keep or remove metadata such as camera details and location. Convert a batch in one go and download all the results in a ZIP.

Questions
Is a JFIF file the same as a JPG?
Essentially yes. Both contain JPEG-compressed image data. The difference is mostly the file extension, which is why some programs refuse a .jfif even though they could read it.
Could I just rename the file?
Often, yes. Renaming .jfif to .jpg works in many cases. This converter is useful when you have many files, also want to resize or compress them, or want a cleanly re-encoded file.
Does re-saving reduce quality?
Re-encoding a JPEG always loses a little detail. At 95-100% quality the change is very small. If you need the exact original pixels, renaming is the lossless option.
What does “Keep metadata” do?
When ticked, the EXIF block from the original file (camera, date and possibly GPS location) is copied into the new JPG. Leave it unticked to strip that information, which is the default.
